Introduction

Although it is quite possible to turn on the Flytec 5030 GPS and go flying straight away, we
recommend that you study these operating instructions and make yourself familiar with the
various functions. ( the latest changes are marked in grey )

We have kept the operating instructions as brief as possible. For people who would like to
freshen up on the basics, or those who want to learn the individual functions and their uses,
we have included in-depth explanations in the appendix. These are referred to within the
basic instructions.

As with all the other operating instructions for our flight instruments, this manual will be
posted on our homepage under Service/Download on the internet. Only the latest version
posted provides the most up-to-date information, any new innovations, or technical
alterations. It is, therefore, highly recommended that you check back on our web site from
time to time.

The software program of the Flytec 5030 GPS is stored in a 'flash' memory. Upgrading your
unit's software to the most recent version can be done with the help of a PC and does not
necessitate outside service. The cable required is included.

As with any electrical unit, you should protect your Flytec 5030 GPS from excessive heat,
hard impacts, dirt or moisture. To ensure the best possible performance, try and keep the
instrument as far away as possible from where the radio antenna is attached.

Please look first at the pictures of the Flytec 5030 GPS (see page 2), then study the
descriptions so that after scanning the index briefly, you will have an overview of the unit's
functions.

For the first time with flight instruments, we have included two 'software' keys on the Flytec
5030 GPS. These are the F1 and F2 keys; their function depends on the display mode. For
example, after switching on, F1 means “next function” and F2 “adopt 1013 hPa or GPS

Altitude”. However, in the Set Mode for the waypoints, F1 stands for “Insert WP” and F2
“Delete WP”. In each case the meaning of the keys is shown on the display.

The Flytec 5030 GPS has a simulation mode feature which helps you get a better
understanding of the numerous possibilities which the Flytec 5030 GPS offers as well as the
theory of gliding flight. With this feature you can simulate just about any situation
encountered during flight. The user can change many settings, from descent and ascent, to
airspeed or groundspeed as well as the flight direction, or also the altitude and can observe
the effects of these on other indicators, such as Best Speed to Fly, McCready ring , arrival
altitude at destination, and distance from the destination etc. The acoustics are also
simulated.

Turning the Unit On and Off

The unit is switched on by pressing the ' /ESC' key. You must confirm the switch on by
pressing the “Enter” key.
To switch it off you need to press the same key for three seconds. The unit will then display
the question 'Really switch off?' Confirm by pressing “Enter”. After a long flight with short
record intervals the calculation of the digital signature can take up to one or two minutes.
Please wait until this process is finished. Press

/ESC key again to turn off the unit.

1 Flight Functions

1.1 Analogue Vario

The most important instrument for any kind of glider is,
without a doubt, the vario. It displays the vertical speed
in metres/sec. (ft/min) and informs the pilot whether
he/she is climbing or sinking. It is only by using the vario
(and its accompanying acoustics) that a pilot can
discover the most efficient climb, and in the opposite
situation, to recognize when they are sinking too rapidly
in descending air which must be avoided.

The scale of the analogue display is 0.2 m/s (or 40
ft/min).
The first full-scale range is from 0to+/-4m/s (800 ft/m),
after which the display switches automatically to a range
from 4 to 8 m/s (800 to 1600 ft/m). The time delay of the
analogue vario is factory set at 1.2 seconds. This can be
changed to any value between 0.6 sec and 4 sec,in the
Set Mode/Basic-Settings/Vario-Speed response delay. If
the time delay is too short, the vario is very twitchy; if too
long, it's rather sluggish.

1.2 Altimeter and Air Pressure

The Flytec 5030 GPS has 4 altitude displays.

Alt1 is always the absolute altitude altimeter above sea level (QNH).
Alt2 in the user selectable fields is a relative reference height altimeter and can be changed

with the arrow keys  . The Next Func/F1 must be set to Mod A2, to perform this setting;
Alt2 can be zeroed at any time by prolonged pressing on F2/Clr A2.
Alt3 Shows the total height gained during a flight. With thermal flights this is dependent
on the flight time. If several pilots complete exactly same flight task, then the one who
climbed the least would have flown most efficiently.
Alt2 and Alt3 are among the user selectable fields
As well there is another altimeter called “Flight-Level” FL (ft) ; It cannot be adjusted by the
user and is based on an air pressure of 1013 hPa at mean sea level.

Altimeter Alt1 should be adjusted to display the correct height above sea level. It is originally
set by the manufacturer to a sea level pressure of 1013hPa. Since this is seldom the case,
the correct altitude should be set before commencing each flight by using the arrow keys,

increases altitude,  decreases altitude. The Info line is telling Mod Alt1  By means of
this adjustment the air pressure display changes too. This air pressure (QNH) always refers
to sea level.
During flight recording Alt1 adjusting is blocked.
The user can obtain the altitude of a location even if this is unknown by setting the sea level
air pressure (QNH) (rec. from the radio) in the set up menu. Or he/she can press the F2
key. If the unit receives satellites the GPS altitude is taken over to Alt1. If there is no
Satellite reception the 1013 hPa altitude will be used. (Same as FL (ft))

A2, A3, FL (ft) and QNH can be displayed within the user selectable fields. (See A7 )
If Alt2 is set to zero for any planned landing area, then the height above this location will

always be indicated after starting. The associated air pressure (QFE) is the actual air
pressure in hPa at this spot, which deviates from QNH, the pressure at sea level, according
to the difference in altitude.

1.3 Digital Vario and Netto Vario

The digital vario has a scale of 10 cm/s (20 ft/m) and a very wide measuring range of +/- 70
m/s. It is therefore also ideal for displaying extreme vertical speeds, such as parachute
jumping.

The digital vario can be set to function as an averager (also called integrated vario), with an
average time delay between 1 and 30 seconds. This is very useful in determining the actual
strength of a rough thermal. The digital vario can also serve as a net or air-mass vario, which
shows the vertical motion of the surrounding air. (Please read section 5.2 Net Vario.)
Additionally, it is possible to set the digital vario to serve as an averager during climbing and
as an air mass vario during gliding. (Set-Mode/Basic Settings/Digital Vario Mode)

1.4 Speed

Airspeed is one of the most significant pieces of information besides vertical speed and
altitude. Increased safety is not the only result of having an exact ASI;( Air Speed Indicator )
it also increases performance during distance flights. The Best Glide, the best McCready
Speed, as well as the Net Vario can function with gliders only when the exact airspeed is
known.

The Flytec 5030 GPS has two independent speed sensor connections.

1. For paragliders the wind wheel sensor is still present. Advantage: it shows the true
air speed and begins to make correct measurements above 1km/h; it is also well­suited in determining the wind strength at take-off.
Enter Basic Settings/Speedmode ,here it's possible to adjust a lower ( - 10 km/h )
speed range for paragliders ( 20 … 60 km/h.)

2. For hang glider pilots there is a built-in, pitot pressure indicator which is capable of

showing speeds of up to 150 km/h (94 mph); however, it only begins to work
at 30 km/h. If necessary, the pitot tube can be lengthened by a flexible hose to
a turbulence-free spot on the glider.
All “rigid-wing” pilots will appreciate the new analogue speed scale with the precise
distance between stall-speed and actual speed! ( see front picture )

Both speed sensors can be adjusted with a correction factor. The factory adjustment is
always 100% in each case. (Setmode/Basics Settings/ Airspeed correct)

With 2.24 it is possible to set a constant offset onto the pitot tube speed. This Offset in will
be added or subtracted (Depending on the sign) to the actual speed value. This offset is to
compensate for the slower air stream under the airfoil. We recommend to keep the “Airspeed
correct pitot” on 100% if you enter an offset value

The wind wheel sensor measures the true air speed. True air speed = TAS.
The pitot pressure sensor, however, measures the indicated airspeed = IAS
Should you be unfamiliar with the difference in these concepts, please refer to: 5.3 - True
and Indicated Airspeed in the appendix.

Speed readings are in both analogue and digital displays. The user can choose whether
he/she wants to view this as a True or Indicated airspeed in the Set-Up Menu. It does not
matter which sensor is used as internally both speeds (TAS and IAS) are always present.
For pilots, who are flying both, hang glider and paragliders the pitot-speed-sensor can be
switched off in the Setup menu Basic Settings/Airspeed correct, pitot. ( the pitot-sensor

7/53

Flytec 5030 GPS

cannot be used with a paraglider ).
The Flytec 5030 GPS is offered in two different versions:
For hanggliders with a built in pitot sensor
For paragliders without this sensor
If you plug into a Flytec 5030 GPS with pitot sensor the wind vane sensor , only the speed of
the wind vane will be displayed.

1.5 Speed without speed sensor

Many paraglider pilots fly without any speed sensor. In this case, a user selectable field can
display a Calculated Air Speed. This issue is calculated by a vector operation of ground
speed and wind.
Note: The wind vector only is available after flying some full circles and it is updated with
every following circle during the flight. The duration for one circle should be longer than 12s.
The calculated air speed always is a true air speed.

1.6 Stall Alarm

The speed for activating the stall alarm can be adjusted in the Basic Settings, and likewise,
the altitude can be set to the point from where up the alarm is active. If the stall alarm is set
at the lowest adjustable value of 0 km/h (mph), it is turned off. The trigger point for the stall
alarm is always linked to the indicated airspeed. At greater altitudes i.e. in thinner air, the
alarm will be activated earlier (i.e. at a higher flying speed) than at sea level. The new
analogue scale allows to test this effect very easy by adjusting the height Alt1 at some 1000
m higher.
(Please refer to: 5.1 Stall Alarm in the appendix).

1.7 Acoustics and Volume Level

Each time the key /Menu is pressed briefly, the volume level is increased by 25%. The
adjustable sound levels are: 0- 25% - 50% - 75% - 100% - 0. The value of the chosen
volume level is displayed on the status line.
Automatic volume control: The basic setting levels 25%, 50%, and 75% will be slowly
increased automatically once the airspeed exceeds 40 km/h (25 mph). It is impossible for the
volume to exceed 100%.

The following settings can be made in the menu under 'Basic Settings /Vario tone'.
Ascent Freq: The ascent acoustics start at a climb rate of 0.1m/s at a 'frequency modulated
interval' tone (peep, peep, peep,) whereby the pitch and frequency increase rhythmically the
faster one climbs. The pulse/pause ratio is 1:1.

AscentF

Beep frequency The basic frequency will be heard when the vario is at 0m/s, except

when it is suppressed at the starting point.

8/53

Flytec 5030 GPS

Modul

Modulation (see graphic below)

SinktoneF

Sink tone/alarm The basic tone deepens when sink increases.
Frequency base you can choose the pitch of the sink tone (or sink alarm) under

‘Sinkton Freq’. (factory setting = 700 Hz ) The sink tone is continuous
and decreases in frequency as the sink speed increases and
increases in frequency when approaching rising air. The descent tone
can be turned off by pressing the button /Route briefly. If you turn it
back on, you would then hear the start frequency and the analogue
vario display would show the starting point of the decent. Under
‘Basic Settings/Sink tone threshold’ you can choose the point at which
the sink tone will start. It cannot be set to a higher frequency than the

climb acoustic frequency. The basic tone acoustic may be set lower.

damp

Dampening The vario value is re-calculated every 0.2s. Rapid vario changes may

result in wide variations in tone frequency (pitch). The ear registers it

as a fast piano effect. In order to change this, a damping may be

added. Damping the rapid tone and frequency results in the vario

being more settled.

Beepch

Beepchose From Vers.2.21 on, it is possible to choose two different acoustic

settings under „Beepchoose“ in the Basic Settings. 0 is the old setting,

and 1 allows you to choose, that the acoustic increases or decreases

during a beep.

9/53

Flytec 5030 GPS

Pitch

Pitch, broken tone interval (see graphic below). The broken tone intervals increase in pitch
with height

In the basic settings it is possible to set the following thresholds

Sink tone thres.

Threshold The starting point can be chosen as in climb acoustic.

Audio thresh.

Threshold To avoid the climb acoustic starting on the ground or during very slow

climbs in flight, the starting point can be set from 0.02m/s to 0.2 m/s.
The warning sound for the stall alarm is a pitch tone of medium height with a very fast

interval rate and is always at full volume (100%). (Please, read 5.1 Stall Alarm)
McCready tone: When gliding with McCready sound activated, a tone is heard that

corresponds to the McCready ring value. This tone cannot be confused with the normal
ascent tone, as it has a pulse pause ratio of 1:4. (Please read 5.5 McCready Theory.)
The warning tone for a negative McCready Ring value is a deeper tone with a rapid
interval sequence, which tells the pilot to fly faster immediately.

All of the sound effects described here can be heard in the simulation mode.

1.8 User selectable fields

In the lower part of the display beside the compass rose are 7 user selectable fields which
can be used as the pilot desires. In total, there are about 22 measurement options available.
In order to assign a field, press the

display is highlighted by a black bar. Repeatedly pressing the

1.8.1 Temperature

The unit needs a temperature sensor, not only for compensation of the pressure sensors but
also for automatically regulating the contrast of the display. The temperature reading can be
in either Celsius or Fahrenheit. (Set-Up Menu/Basic Settings/Units)
Note: The sensor measures the circuit board temperature. The inside temperature of the
casing can be slightly higher than the ambient air temperature, especially when in direct
sunlight.

1.8.2 Time and Date

Note: Time does not need to be adjusted as it is automatically set by the GPS receiver.
However, to set the unit to local time, any time zone difference from UTC (World time) will
need to be entered, which corresponds to a positive value if the time zone is east of
Greenwich or a negative if west. It is also possible to enter half hour time zones by adding a

0.5h shift to the set time zone
Note: After entering day, month, and year, it is essential to ensure that the data is correctly
received by the internal RTC (Real Time Clock) which can be executed only when the GPS
receiver is active and receives satellites. Otherwise the date will not be accepted. Please
note, that internally all times and dates are calculated with UTC

1.8.3 Flight time

The take off time is automatically recorded. Recording of data and the clock for the flight
time start as soon as the speed over the ground or through the air reaches a reasonable
flight speed and altitude difference. The condition for starting the record is a ground speed of
more than 10km/h for at least 60seconds or an altitude difference of 30m within 60 seconds.
The GPS receiver must be active and must have satellite reception. If the GPS receiver is
switched off, only the 30m altitude difference are necessary. Only flights with a duration of
more than 3 minutes will be recorded in the log book.

The flight time can be displayed in the user selectable fields. The unit will also recognize the
end of the flight. The end of a flight is reached if the speed is lower than 10km/H and the
vario is lower than 0.1m/s for 60s. In basic settings you can choose between manual and
automatic start and ending of flight recordings. (Also see 3.2 - Flight Memory.)

1.8.4 Track and Bearing

As is the convention with GPS receivers, the Track is defined as the route of the aircraft
over ground. Geographic true North is always 0 or 360 degrees (East 90, South 180, West
270 degrees). The bearing is the direction to a specific destination or waypoint from the
aircraft, expressed in the same way as above.
Note: A Tracklog is the result of recording many different position points during a flight.

1.8.5 Distance to Waypoint

The horizontal distance is displayed for the viewer to the chosen waypoint as long as the
destination has been input automatically or manually with the Goto function. For distances
under 10km the resolution is 10m, if farther it is 0.1km. (Please read – 2.7 Goto-Function)

The distance to a WP is always measured to the centre of a WP cylinder an not tits circum­ference.

1.8.6 Glide Ratio (=L/D Ratio)

By definition, the glide ratio is calculated by taking the horizontal distance travelled and
dividing it by the height lost

Attainable glide ratios in calm air for the following glider types:

Following different types of Glide ratio can be selected within the user-selectable fields.

Glide ratio through the air:
L/D air =TAS / Sink True airspeed divided by sink

Glide ratio over the ground:
L/D gnd = GS/Sink Ground speed divided by sink

Required glide ratio in order to reach the chosen destination from the present position.
L/D req. = Distance to the waypoint divided by the height difference to the waypoint.

1.8.8 Alt ab.Goal

This Userfield shows the calculated altitude above goal ( = the last WP of a route) with
taking in account all the remaining sectors of a route in front of the pilot. For all sectors the
belonging wind component is taken into account. Particularly useful is this function when a
competition pilot gets the information when to leave a good thermal even he has to pass by
further waypoints. This calculation is based on the speed of best glide.

1.8.9 Distance to cylinder of a waypoint in a competition route

This user defined field shows the distance from the actual position to the radius of the actual
waypoint in a route or chosen. This is true from the inside in case of a start cylinder with
EXIT or from the outside in case of a waypoint in a route. This helps to decide how far the
next turnpoint is.

1.8.10 Userfield L/D req to goal

This Userfield shows the necessary lift/drag ratio above ground to the goal over several
Waypoint. This Userfield is indicated only if a route is active. Thus it can be decided whether
one can fly directly over several waypoints to the goal, or whether one must gain height
before heading to goal. The calculation does not take into account, if there is a waypoint
higher than the direct line of the current height into the goal. The distance is calculated as in

The accuracy of the indicated value depends on the length of the active leg. Largest
inaccuracy arises in the centre between start and a goal, if one is very close at the track (the
angles become very flat). With 50 km distance between start and a goal the inaccuracy can
reach up to. Positive values are indicated, if one is on the right of the track, negative values
on the left of the track. Even if one flew over the next waypoint the distance from the straight

1.9 Speed to Fly (For best Glide)

Please look at the Analogue Speed scale. On the right hand side of it there is a thick arrow
which informs the pilot of the speed for best glide. This will show the optimal glide speed,
which is dependent on the polar of the glider, the wind strength and direction and the
rising/sinking of the surrounding air. In competition, a pilot will always fly faster than this
speed indicator is recommending except when every meter of height is essential.
(Please see also 5.4 – Polar curves and required speeds.)
It does not matter whether the pilot has chosen to set true or indicated airspeed, as
Flytec 5030 GPS compensates for this. However, the true value of the best glide speed will
increase with increased altitude. (See also 5.3 - True or Indicated Airspeed.)

1.10 McCready Ring

The single pointer at the climb range of the analogue vario, shows the value of the
McCready ring.(See title photo)
The position of this arrow is dependent on the polar of the glider, the wind, the rising or
sinking air and, above all, the flight speed. If a pilot wants to complete a competition task in
the shortest time possible, then he/she needs to strive continuously to keep the McCready
pointer as close as possible to the average climb rates achieved in thermals. Due to the fact
that the indicator is dependent on many conditions, we call it an active McCready pointer.
(Please refer to: 5.5 McCready Theory.)
By pressing the key McCr /Mark it is possible to turn the McCready sound on or off. The
pitch of the tone is linked to the pointer. That means that the zero point of the McCready
acoustic is set to this value where the McCready pointer actually points to. Adjust your speed

16/53

Flytec 5030 GPS

so that the McCready arrow points to the day specific climb rate and then briefly press the
McCr /Mark key. The McCready acoustic zero point is now set to this desired McCready
position and you can fly purely with the acoustic, optimal for distance travel, and removing
the need to glance at the instrument continuously. If the McCready acoustic is switched on,
the daytypical climb shows in black, the toneless gap is shaded. If the tone lowers, then you
need to speed up and vice versa; you should keep the pointer and the tone at the same
position.
In order to offer the pilot additional help it is possible to set an acoustic dead band around
the chosen McCready ring value (this is that position of the McCrdy pointer when the user is
activating the McCrdy sound by pressing the key McCr /Mark ) This means, the pilot flies
correct according the McCrdy theory when the instrument is quiet. In the Setup menu Basic
Settings/McCready one can adjust the wideness of this dead band. (Factory setting = + - 30
cm/s) With the same key, you can set a delay in seconds for the restarting of the McCready
sound after leaving a thermal. (Factory setting = 7 seconds)

1.11 Average Thermal Climb

There are good and not so good thermal days. The average climb even varies throughout
the day. Climbing is generally better at midday than in the morning or the evening. The
Flytec 5030 GPS has, for this reason, a grey area in the double edge of the analogue vario
display which indicates the average thermal climb and is necessary for the McCready theory.
We can call this pointer average thermal climb display for a selectable time. ( See title
photo ) It is solely influenced by the climb and shows the average thermal strength for the
last 1 … 10 minutes of climbing. (adjustable at Basic Settings/Average thermal climb )
The pilot flies optimally, when the active McCready pointer, covers the end of the average
thermal climb area. (See also 5.5 – McCready Theory)

1.12 Battery Management

The Flytec 5030 GPS has a high performance NiMh (nickel metal hydride) accumulator. This
rechargeable battery can be charged with a plug-in charger (230/110 V AC), by using a
vehicle battery (10 –18 V) or by means of a solar panel. The accumulator is built into the
casing and requires no maintenance. A charging cycle (for empty batteries) is approximately
4 to 6 hrs. An intelligent charging unit in the Flytec 5030 GPS recognizes when the battery is
full and stops charging. It is therefore impossible to overcharge the battery if you forget to
unplug the charger. Nevertheless we recommend that you unplug the charger for safety
reasons when charging is complete.

A fully charged battery should last for 22 hours with both vario and GPS receiver switched
on. The battery life will be more than doubled if only the vario is used. Please bear in mind
that the battery's capacity decreases at very low temperatures. When the battery capacity
has dropped to about 10 %, an alarm tone sounds and the message “Low bat GPS off” will
appear on the display. The GPS receiver, which consumes over half of the energy, will be
shut off, and the remaining energy will be sufficient for using the vario for another 2 to 4
hours. However, if a pilot definitely wants to keep recording the GPS position, he/she can
turn the GPS receiver on again (within 30 seconds); flight recording will then continue
uninterrupted.
If a critically low voltage threshold is exceeded, the unit switches itself off. Although the
battery life indicator is temperature compensated, we recommend that you start with at least
50% of the battery capacity for longer flights. A bar graph scale shows the battery charge
level. In addition, its voltage is also measured and the remaining battery life is calculated in
hours. The indicated battery life will appear too high direct after charging.

17/53

Flytec 5030 GPS

The Flytec 5030 GPS comes complete with an adaptor, a cable with a cigarette lighter plug
for your personal vehicle and a computer data cable.
The battery's nominal voltage is 3.6 Volts. During charging the voltage rises to 4.4 volts; in
place of the bar scale the word “charging” appears. During normal operation the voltage is
between 3.5 and 4.1 Volts.

The yellow light diode will blink several times after plugging the unit in (to test the battery's
condition) and stays lit until the recharging is complete. If you leave the unit plugged in to
the charger for a few hours after the diode's light has gone out, it will switch to trickle mode
allowing the stored energy in the battery to increase by a few percent.

Note: The outside temperature should be between 10 and 30 degrees Celsius when
recharging the battery. You can check the battery voltage during charging, but normally the
unit should be turned off during this process.

Bat. 3.57V 12h

After the battery has been permanently built into the unit, the user should not try in any way
to replace it himself. In the event that a replacement should be necessary, the unit should be
sent to FLYTEC AG for testing. We will also take care that the battery is properly disposed
of if necessary.

2 GPS Functions

The use of GPS receivers has become indispensable for navigation today. A chain of
satellites circles the Earth. Their orbit takes approximately 30 minutes. Already more than
30 satellites have been sent into orbit by the USA. Fortunately, these may be used for
navigation free of charge. Some of them do not function any more. Nonetheless, it is
possible to determine your position very precisely anywhere in the world by receiving several
satellites at the same time.

2.1 Assessment of Reception Quality

Flytec 5030 GPS's GPS receiver can be turned on and off by prolonged pressing of the Fl
button. It can follow up to 16 satellites at the same time. After turning on the unit it is
necessary to receive at least 4 satellites to fix position for the first time. Once logged on, 3
satellites (for 2D positioning) are sufficient for further navigation. However, if you want to
record altitude too (3D positioning), then four satellites are required. There is a table in the
receiver, The Satellite Almanac, in which the path, place, and time of all satellites are kept
with reference to the receiver. The Almanac is continuously updated during signal reception.
However, if the signal to the Almanac memory is disrupted completely or the unit is taken
200 km or more from the last reception point, then the Almanac has to be re-established; it
can take 10 minutes to determine the new position. Power is still supplied to the almanac's
memory even when the unit is turned off.

When the receiver has been moved a great distance, you can help facilitate the connection
with the Almanac by putting in the approximate new position (whole number coordinates
suffice) in the Set Up mode under ‘Basic settings/GPS Init’. With the antenna unobstructed
the unit will normally recognize its position after a few minutes.

If the receiver is turned off for only a short period of time (less than 2 hours), it takes less
18/53

Flytec 5030 GPS

than a minute to determine the location. Buildings, mountains or thick forest affect reception
quality. Therefore, you should always look for the best possible visibility around you and the
antenna under the Flytec 5030 GPS label should point upwards. When the units is fastened,
it should not have more than 45° deviation from a horizontal position.
Because the receiving strength of the satellite signal is only 1/1000 of mobile radios, these
radio receivers and other disruptive factors (like notebooks) should be kept as far away as
possible from the Flytec 5030 GPS.

Together with the navigation signal, information about the number of received satellites is
shown on the right side of the bar scale. The value for the reception quality is determined by
the length of the bar. The longer the bar, the more precise is the reception.

2.2 Compass and Flight Direction

In contrast to a normal magnetic compass which is oriented to magnetic north, the GPS
compass can show direction only when the user moves about. However, it has the
advantage that it is not subject to any grid deviation and does not show any deviation as a
result of iron or any magnetic material either. Its zero point always corresponds with true
geographic north (0 or 360 degrees). The course that is the flight direction (= Track), is
calculated from your movements.
If the user remains stationary at the same location, then the course and compass needles
are inoperative. The exact course (that is the direction in which the user travels over ground)
is always at the top of the compass, but can also be read in the display “Track”. When
circling in a thermal the compass rose appears to turn; in reality the needle does not move;
the unit along with the aircraft, moves around the rose.

2.3 Ground-Speed

The GPS receiver fixes its position once every second. Speed over ground is derived from
the distance between these positions. Only from the difference between airspeed and
groundspeed can one make conclusions about the wind's influence, and ultimately these are
the most important pieces of information a pilot needs during flight. The ground speed
should appear at all times in an user selected field.
With a paraglider Flytec 5030 GPS (without a pitot sensor), the GPS speed is shown
automatically in the large analogue and digital scales if no vane sensor is plugged in. The
same applies when in the Basic Settings /Air Speed correct pitot, the function of the pitot has
been deactivated. (Use sensor? = No )
In this case it is possible to use a calculated airspeed in a user selectable field. This issue is
calculated by a vector operation of ground speed and wind.

Flytec 5030 GPS

2.4 Head, Cross and Tail Winds; the Wind Component

During a goal flight or in calculating a final glide, it is the wind component (i.e. the difference
between Ground speed and Air speed) that is important. In most cases the wind does not
blow directly from the front or from behind, but from the side. If the wind component “Spd­Diff' (in the user defined fields) is positive, then the pilot will fly with a tail wind and the glide
ratio over the ground will improve. If it is negative the glide ratio will worsen. The Flytec 5030
GPS takes the wind into consideration when calculating the best speed to fly and with final
glide calculations. (In order to find the correct angle between the destination and the wind
when a strong cross wind is present, please refer to the section 2.7 Goto function.)
Press several times at F1 until the info: HT wind = auto sh
this automatic calculated
windcomponent can be overwritten by
a manual input of a head-wind (with
negative sign) or a tailwind. Please
refer to 5.6 Final glide calculation.
But be careful with this manual win
input. The results will be wrong when
changing your flight direction. Anyway
the field SPD-Diff always displays th
real and actual difference between
Ground and Air speed and could be used for a check or a required correction.

.5 Wind Direction and Windspeed

2

is very important to know the wind direction and speed before an out landing.

It
The wind speed can be selected within the user defined fields. It is necessary to
two complete circles as steadily as possible. Whilst circling, the Flytec 5030 GPS
determines the wind direction and speed. Wind direction is shown in the compass
small windsock. During the landing approach this symbol must always be at the top.

.6 Waypoints and Coordinates

2

waypoint is any single point on the earth's surface that you would like to go to. The Flytec

A
5030 GPS can save up to 200 different waypoints. Each waypoint can have up to 17
characters, e.g. “Laber Airfield”. In determining the waypoint, it is also necessary to e
the altitude, i.e. “1865” meters above sea level. We still need the waypoint co-ordinates.
(Please also refer to 3.3 Waypoints – Alter, Delete or Add.)
For this the Flytec 5030 GPS utilizes the most international a
geographical maps with the name WGS84 (World Geodetic System 1984). This
system assumes that latitude is measured from the equator (0 degrees) to the North Pole,
90 degrees North, and to the South Pole, 90 degrees South. Longitude is measured from
the Greenwich meridian (London 0 degrees). East is positive (up to 180 degrees). West is
negative (-180 degrees

Example: M.22.04 11:16:49 for 22 April 11 hrs.16 minutes 49 seconds. (UTC). Of course
this WP name can be changed later into a more meaningful name, i.e. “Aunt Renate”. (For

by flying at the best glide speed. Every meter above that means a greater safety margin. As
soon as Alt above WP or Alt above BG are showing positive, both fields will change to
inverse display (see photo above)
With a good thermal, it makes sense to begin the final glide if Alt a WP shows

zero.
The Alt a. BG then shows him/her how much height he/she will have available as se
to use if necessary, to compensate for unexpected sink. Under no circumstances should
one go ahead and fly towards goal if the Alt a BG (Height) shows zero or negative numbers
reaching goal would be impossible without lift on the way.

.8 Flying Routes

route is an arrangement of various waypoints. Of course, the waypoints used on a route

have to be saved in the unit's memory. The pilot should optimize his/her time flying from WP
to WP in a similar manner used with the Goto Function; this means that he/she can
complete a task in the shortest possible time with the help of the McCready theory.

o choose a route, you press the button / Route for a few seconds. Each route should

T
also be assigned a route name, such as “Karwendel Triangle”. It makes sense to store
many well-known thermal sources as waypoints along a route. The pilot does not have to
feel compelled to reach these waypoints; at times he/she may be high enough to jump a
waypoint on a route, and another time he/she has already found the thermal several
kilometres before reaching the waypoint. Of course there is still the option of looking
other, possibly closer, waypoints without leaving the route one is on by using the Goto

2.9 The Competition Route -

For Record Flights, Perform

In

contrast to the routes described above, the Comp. Route has waypoints which are man­datory and have to be reached; for example turning points in competition or on Comp.
performance flights. The regulation, which only recently came into effect in documenting
distances flown, replaces the detailed and often difficult to interpret photographic
documentation with photo sectors; it is now totally dependent on the recording of GPS
receiver position data (Tracklog points).
When flying Comp.-routes the pilot will be
circumference of a turnpoint cylinder or when entering /
leaving the start cylinder and the unit switches automatically
to the next WP. The Competition route can be called up by
prolonged pressing of the 
by pressing Enter. (Please refer to 3.5 to set and change
routes.) Here any of the WPs can be defined to be the Start
WP.

In

place of the previous photo sectors, the pilot must enter
the radius of the cylinder. This cylinder radius can be set
separately for every WP , between 20m and 200km,. The
customary factory setting is a radius of 400m. Please note
that different radii for start/landing cylinders can be changed

U
setting or changing the route, the McC/Mrk key is pressed, an “S” for Start-Cylinder
appears behind the waypoint's name and the cylinder radius. (The “S” disappears if the
same key is pressed again) Only if a WP is marked with “S” it is necessary to set also a
Start time and a Startmode : Enter or Exit. By confirming Enter or Exit he/she defines if th
race begins by flying in or out of the circumference. If no Start-Cylinder is determined the
pilots can launch whenever they want; the automatic switch over to the next WP occurs as
soon the pilot is inside the cylinder .
During a flight with defined starttime t
seconds/minutes are left before the opening of the Start line. The time counter show
decreasing negative numbers Only when the time counter has reached 0 and star
count forward ( now with positive numbers) the pilot can make up his mind to cross the
circumference of the start cylinder from outside to inside if the start mode was set to ENT
and the other way round if the mode was EXIT. An unmistakable bleeping sound occurs and
the Flytec 5030 GPS switches automatically to the next WP.
The Dist.to WP always counts the distance from the present pilots po

2.10 Relocating Thermals

With weak or widely dispersed thermals this function helps to relocate any lost thermals. A
small arrow pointing up in the double ring of the compass rose shows the direction to the last
thermal with at least a 1 m/s climb. If this arrow is displayed at the top in the ring then you
are flying towards the thermal. However, if the arrow is below in the compass rose, you are
going away from the thermal. (See title photo ) If you want to take advantage of this
function, then the indicator “Dist. to ^ ” should be activated in one of the user defined fields.
This value indicates the distance from the last thermal (with a climb rate of 1 m/s ) to the
pilot.

2.11 Restricted areas CTRs

The structure of the restricted areas inside the memory has changed from version 2.19a to

2.21. You can not use the old CTR's, but it is possible to transfer them from the old structure
to the new structure. Due to this change it is also not possible too use the well known
“Maxpunkte” to transfer CTR data to the instrument.
The advantage of the new structure is, that you can use now unlimited corner points (Only
limited by memory capacity). You can use also radii and circle segments. After updating the
instrument to version 2.21 you will find one CTR in the list , the CTR “Innsbruck”. You can
edit this CTR to your needs, or set a new CTR with Flychart, but it is only possible to use
one CTR. As an option with costs you can have a release code for the optional SW­packages from Flytec. This is possible for 20 CTR's or with additional EEPROM memory up
to 300 CTR's. It is possible to retrofit a bigger EEPROM in older instruments with only 128kB
of memory. The memory size is displayed in the lower part of the startup screen.

When entering these corner points or waypoints , pay attention that the list of waypoints
follow one after another, the same way as the lines of the polygon should be drawn. For the
last WP it is not necessary to repeat the first one. To close the polygon, the program
automatically connects the first and the last WP with a line.
The transfer of the waypoint list of a CTR to the Flytec 5030 GPS could be done, either
manually in Setup mode / restricted areas or, with less afford, with a PC program, i. e.
Flychart which will is available at our website:

A new field Dist.to CTR was created among the user defined fields. It displays the closest
distance to the next CTR so long as this distance is less than 50 km. To increase accuracy
the distance between two Waypoints of a CTR should not be too long. We recommend to set
some free waypoints in the middle of longer straight lines.
Setting up a CTR, one can choose and alter a warning limit. In flight, the graphic as well the
normal display will show an additional distance information in the info field CTR 0.75 km

It is possible to enter a comment of maximum 17 characters to each CTR beneath the name.
You can show the 5 next CTR’s with a brief press onto the right arrow key, if you are in the
map screen. The left key shows the comments of the five next CTR’s The comment can be
used to enter as an example the max or minimum altitude of this CTR or the RF frequency of
the tower. The list is sorted in the shortest distance of the next 5 CTR’s

Since Flytec 5030 GPSs market introduction we constantly have made remarkable
improvements with many software updates with a lot of benefits for our users. Please
appreciate that for the first time we are asking a little fee for a release code to open the
option: Restricted areas

Pilots who want to use the CTRs should call us up via phone, fax or e-mail and give us the
serial number of the instrument. In return we will send them the Release Code, depending
on the units serial number.

3.2 Flight Memory and Flight Analysis

In contrast to previous flight instruments the recording mode does not need to be specially
activated as each flight is automatically saved.
The flight logging system used in the Flytec 5030 GPS registers not only the flight altitude
and speed, but also logs, with the GPS receiver switched on, the time, position of the pilot in
the WGS84 coordinate system, the GPS altitude and flight speed (= air speed).
The value set in the Basic Settings/ record interval determines the time interval in seconds
after a new data record is written in the Flytec 5030 GPS's memory.
A scan rate of 2 second is advisable for tests or aerobatic flights. The factory setting is 10
seconds. In order that such a flight is logged in the flight memory, it has to be at least 3
minutes long . For the beginning of a flight the following rule applies:
The start is recognized as soon as the groundspeed reaches at least 10 km/h or if the
instrument recognizes an altitude difference of at least 30m. In each case however, the

31/53

Flytec 5030 GPS

previous flight history with up to 30 recording points is logged in the Flytec 5030 GPS's
memory.
Even the last 3 minutes before the start of the logged
flight can be recognized as they are recorded with a
10 second recording interval. An end of flight is
recognized if there is no movement for 60 seconds,
and no change in altitude occurs. Then the Flight
analysis is displayed. The digital signature is
calculated from this moment on and a notice in the
user defined field draws attention to it. Please wait
until the calculation is completed. You can return to
standard mode by pressing the Menu key briefly. Or
you perform a recalculation of the Digital Signature
by briefly pressing F2.

If however, manual recording was chosen, recording
starts 1 minute after the instrument is switched on
and continues until the Esc key is pressed for 3
seconds. The unit asks you:
“Do really switch off” and you confirm with “ Enter”

Now starts the generation of the digital signature
which can last 1 or 2 minutes. Wait until this is done
and press any key to turn off.

Bear in mind that modifying of Alt1 cannot be done
after the start of a record. The user field Flight time
starts to count up with the beginning of a record.

Flight Memory is situated in the second position of
the Main Setup Menu. If you press the Enter key, the
list of flights, stored according to date, appears. The
most recent flights are in the first positions. The
length of the flight is also shown. With the
key you can move through the list and choose the
desired flight with the Enter key. The flight, with its
benchmark figures, is indicated in the Flight analysis.
Individual flights can be deleted from the list by
pressing F2 Del. Flight.

Note: Before starting a flight make sure that the GPS
receiver shows at least 4 receiving satellites to get a
valid recording.

Remark 1: In the flight recording the values are
recorded, which appeared on the display. Because the display is renewed each second, thus
the 1 seconds - values are stored in the flight recording. If one downloads such flight
afterwards with a program such as Flychart, SeeYou, CompeGPS, Maxpunkte etc. on the
PC, these programs can analyze only the flight recording in the IGC format. In the IGC file
the position, the barometric height, the GPS height and the True airspeed with impeller
sensor or pitot tube sensor are recorded. The programs calculate now the rate of climb
values by the altitude values. If the pilot chooses for example a recording Interval of 10s, and
in these 10 seconds an altitude difference of 5m occurred, a climb rate of 0.5m/s is
calculated. In this10 seconds it is possible that however a climb rate of of 1m/s occurred.

Remark 2: Even if the instrument is able to store up to 100 flights, we recommend, to store
the flights on a PC and format the memory afterwards with „basic Settings -> Erase all
records “. This procedure offers security to your valuable flights, and the equipment can
record with a “refreshed” memory..

3.2.1 Graphic Display of Flights in Map Format

The flight route of saved flights can also be shown on the display and viewed. Flight Analysis
is reached by pressing F1 to display the function Show Map. The screen-optimized flight
route is shown on the display. (North is located at the top)
Additionally, stored way-points are plotted with a cross and
name. The map scale is displayed too.
The graph can now be changed as follows:

F2: Zoom in: The map scale is gradually increased to approx.

0.4 km. Thus, individual circles during a climbing period are
clearly recognisable
(This is dependent on the set recording interval).

Fl: Zoom out: The map scale is gradually decreased until the
screen display is optimised. The maximum is 47.7km

Arrow keys: Pan: With these the plotted area can be shifted up,
down, left and right.

Enter: From each graph back again to the screen
optimized graph.

ESC: Back to the main setup menu. All other keys cause the track in the current selection
to be redrawn.

Note: As the picture takes a few seconds to appear, depending on the amount of data, Wait
and Ready appear on the status line as user information; if a zoom or pan key is touched
during the process then it will be broken off and will start over again with new values. You
can thus obtain the desired graph quickly. Even past flights can be graphed as long as they
are still saved.

During flight, touching the ESC key briefly will bring you a real-time track and map display.
Vario, height and speed appear digitally under the map. For FAI routes, the cylinder of the
active waypoint, WP names, and a thin dotted line to the next WP are also displayed. During
the flight the Zoom In/Out functions are accessible.
From Version 2.21 on, the end of the actual track (That means the actual position of the
pilot) is marked with an arrow. The zoom out range is increased 4 times to show the whole
route and the nearby restricted areas. The waypoints of a competition route are marked as
cylinders with their radius and all waypoints of a competition route are connected with a
dashed line

3.3 Waypoints - Alter, Delete, or Add

Waypoints can be managed at this location of the
Main Setup Menu.
After briefly pressing the Enter key the display
shows the list of logged waypoints (WPs).
All WPs are arranged in alphabetical order.
Waypoints WP
If this list contains more than 8 visible WPs, a down
arrow at the right lower edge of the list shows that
additional pages follow. To scroll down to the next
page, press the
shown, and so on. You can select an individual WP
with the
Enter key.
The first letter of the WP name will blink; again with
the
desired letter. There are numbers and letters, as
well as a set of special symbols to choose from. By
pressing the
next letter. With the F1 key you can switch between
capital and small letters and numbers. You can enter up to a maximum of 17 characters.
Once the name has been entered correctly, confirm by pressing Enter. Now the waypoint
altitude blinks, asking for any alterations. Again you confirm by pressing Enter. The WP
position comes next. First the latitude is entered in degrees and minutes, and is confirmed
by pressing Enter. Next are the decimals of the minutes. (Depending on the Coordinate­Format set in the Basic Settings) The same occurs with the longitude. Holding the key down
longer changes the values to be set faster.

Deletion of Waypoints:

Selecting the waypoint to be deleted is done with the
key (Del WP) activates the delete function. To be on the safe side, the Flytec 5030 GPS
asks once again, “Delete Waypoint?” Yes or No are the choices available. It is possible,
however, to stop the deletion process by pressing Esc and returning to a previous level.

Insertion of Waypoints

Pressing the F1 key (Ins WP) activates this function. Entering WP names, altitude, and
position happens in the same way as described above. After confirming all entries with the
Enter key, the new WP is inserted alphabetically in the list.
Altogether 200 WPs can be stored by the Flytec 5030 GPS.

Note: After entering the new waypoints (for example, for inputting them into a route) these
can be used only after you have switched back to the normal flight mode by briefly pressing
the /Menu key. In addition, the route into which the new waypoint should be inserted must
not be active. Therefore, first change into route selection by prolonged pressing of the

3.4 Routes Set - Delete - Alter

You reach any stored routes by marking the menu point Routes in the Main Setup Menu.
Routes saved in the Flytec 5030 GPS appear after pressing the Enter key again. (Maximum
of 20 routes) From these you can select one of the routes to be deleted by using the

 and

 keys; press F2 (DeI.-Route) to delete or Enter key to alter. However, by pressing the Fl

key (Ins. Route) a new route can be created.
A route is a string of waypoints. (Of course the WPs have to be already in the Flytec 5030
GPS's memory). If a WP is used in a route, then it can no longer be deleted.

Setting a New Route

After pressing the F1 key (lns.Route), first a name has to be entered for the route. The
cursor will blink on the first letter of the word “Xxxxx”. By using the
alter each to the desired letter. By using the
change it, and so forth. By pressing the Enter key you conclude the entry of the route name.
At this time the individual WPs need to be added. The list of the available WPs appears in a
alphabetical order in the bottom half of the screen after pressing the F1 button (lns.Wayp). At
the same time you see the request: Select Waypoint No1. Again by using the
keys you search for the first WP and it is added to the route by pressing Enter. This is
indicated in the upper half of the screen. Press the F1 key (Ins.Wayp) again. Once more the
waypoint list appears and you can select the second point. Press Enter to add this to the
route, and so on. The highlighted waypoint (offset in black) in the route is always the last
one entered, which means that the function “lns.WP” will set the next WP to be entered after
the one highlighted in black. If you want to insert an additional waypoint after WP1, then you
highlight WP1, press the Fl key (lns.WP); the reference Select Waypoint No 2 appears.

If you determine, for example, that Waypoint No. 4 must be changed, then you select it and
delete it( with F2 ) and insert a new one by pressing F1 . Note: The marked WP before
pressing F1 must be WP3. Again the list of available waypoints appears and the prompt
Select Waypoint No 4. After selecting and pressing Enter, the old waypoint is replaced by
the newly chosen one.
If you want to delete a waypoint from the route, then you select it and press the F2 key (Del.
Wayp) The WP is deleted from the list without any additional prompt.

Altering a Route:

You select a route to be changed with the
name is changed first. If this is not what you want, then it is sufficient to press Enter again in
order to get to the waypoints. As described in the last paragraph, the additional WP can be
added or deleted now.

Deleting a Route:

You select the route to be deleted with the
on the safe side the Flytec 5030 GPS enquires once again: Delete Route? that can be
answered with Yes or No. However, it is not possible to delete the FAI-route.

Changing a route into Competition Route:

You select the route you want to be the Competition Route with the   keys and press
McC /Mrk. The display asks “copy to Competition route?” confirm with “yes”. Please note:
Start cylinder, cylinder radii and start time have to be set separately. As default all cylinder

3.5 Competition - Route Set - Alter - Delete

Even when a Competition route, called up during flight, is treated differently from a usual
route, there is only few difference when setting or changing it. The route can be set up with
the help of the key board similar to a normal route or can be transferred from the PC.
The FAI route can be altered, WPs in it can be erased, but its name, however, cannot be
deleted.
Each one of the other routes can be copied to replace a Comp.-route with the McC
key. The same key is used to assign the status “Start Cylinder” to one of the waypoints. For
the Start-cylinder the user chooses if the race begins by “Enter or Exit” the cylinder
circumference. To each of the WPs in the Comp-route a different cylinder-radius can be
assigned. There is also a count down timer linked with the Start-cylinder . With its help the
pilot knows exactly how many min. and sec. will pass until the window is open.

A CTR is defined by the end points of lines and arc segments or by the center and radius of
a circle. The end points must be entered exactly in sequential order (clockwise or counter
clockwise). The instrument will automatically connect the last point entered to the first point
so it is unnecessary to repeat the first point at the end of the string. For mathematical
reasons the distance between two end points in a CTR should not lie too far apart. The
accuracy of the distance calculation will be increased if an intermediate point is inserted
between two distant end points.

CTR's can be entered into the instrument manually in the Setup menu>Restricted areas, or
more easily with Flychart. The procedure for manually entering CTRs is below and the
procedure for using Flychart is in the FC help files.

The distance to the nearest CTR can be seen with the user-selectable field "Dist. to CTR".
The display is limited to distances of 50 km. If you fly within the warning limit (default =
2000m) as defined in the CTR a warning comment will be given in the Information Display.
The warning will be given with the distance to the CTR (e.g., CTR 0.75 km). If you enter the
CTR the “Dist. To CTR” will display 0.

If you define the points of a CTR the GPS coordinates (lat and Lon) of the point must be
entered as well as the Type of point from the list below:

3.7 Simulation

After choosing the Simulation mode in the Setup menu and pressing the Enter button, you
reach this very interesting function. With the arrow keys and Enter you turn the Simulation to
Yes. Now the simulation starts at the last known GPS position. With the  and arrow keys
you can adjust the air and ground speed; the  and  arrow keys change the sink or the
climb. If the stall alarm sounds, please increase the airspeed by a few Km/h. Depending
upon the polar entered, you will now recognize the relationships between required speed,
McCready indicator and acoustics.

The softkey F1 is used to change different functions:

Next Func. Mod Alt2  Modify Alt2

Likewise, the Goto function can be called up to select a waypoint. If the direction arrow in
the middle of the compass points upwards, the pilot is moving towards his goal and the
distance to WP becomes smaller while at the same time the altitude naturally decreases. If
you now initiate a climb with the  key, the Flytec 5030 GPS simulates circling up in a
thermal; the compass rose turns and the distance to goal continuously changes between
somewhat closer and somewhat farther away.
Under simulation you also can test the different acoustic adjustments as frequency, pitch
and modulation during a virtual climbing. ( Basic Settings/Vario tone )

Please change back again to a sink flight. If on your display there is a user field named Dist

while in the compass rose the symbol
thermal has been.
You can also retrace a route flown. If you select the route as the Comp.-route, you will hear
the characteristic tone upon approaching within 400 metres of the waypoint, which tells you,
that you are inside the cylinder. You see the automatic switchover to the next WP too. If a
starttime was set, take care that the count down timer shows positive values. By pressing
the ESC key you can switch to map display and observe the approach to the waypoint
cylinder. The second transparent pointer in the centre of the compass rose helps to minimize
the flight path; no need to cross the circumference of the cylinder right angled.
Unfortunately, wind direction cannot be set; only a difference between Ground- and airspeed
simulates head or tailwind influence. Press F1 until the function: wind ▲▼ trk ►◄appears

3.8 Factory Settings, Unit Specific Parameters

Beyond this set up level, which is not accessible to the pilot, all basic factory settings are
stored. In particular, both the sensor specific parameters the serial number and all the
calibration data are located here. This data is not lost even when the power supply is cut off.

3.9 Optional Software Packages

With the help of a password code obtainable from the manufacturer, additional special
functions can be activated. For example, restricted areas CTRs are displayed and CTRs
itself will be graphically drawn in the map mode.

To Enter a release code

• :Chose the appropriate SW package in the Main Setup Menu

• Press Enter. A Code -29XXX appears

• With the down arrow key the code goes directly to 30000 and begins to count down

• Stop if you see the correct code and adjust with the up and down arrow keys

• Press Enter

• The instruments says “Package released”

If you enter a wrong code, the instruments block for 5minutes or longer!

3.10 NMEA data output

The permanent output (1 per sec) of NMEA data via the serial port is now activated, which is
sending three NMEA sentences to an attached receiver. (9600 baud; 8 bit; no Par ;1

4 Data Transfer

All data entered by the pilot, including waypoints, routes, pilots names, etc. as well as the
automatically recorded track log points of the flights undertaken by him/her are in the
memory of the Flytec 5030 GPS. Each track log point contains the time, position, GPS
altitude, barometric altitude as well as the flight speed. In this way, it is possible to graph the
Barogramm, variogramm, speed gram and course of the flight on a map for later evaluation.
Recently, the FLYCHART Programme with Google Earth Interface is now able to depict the
flight in its appropriate landscape on a computer screen in 3D.

4.1 Data Exchange Via PC

Among the items belonging to the Flytec 5030 GPS's basic equipment is a data cable for a
serial PC interface (9 pol Sub D plug). In this way data transfer can occur in both directions.
The connection occurs with: 57.600 baud; 1 startbit; 8 databit; 1 stopbit; no parity, Xon/Xoff

The following can be read and write via this RS232 interface:

Instrument Configuration (User Setup)
Waypoint list
Route list; CTRs

flight (tracks)
Or can be written to the Flytec 5030 GPS:
Waypoints, routes, CTRs, and Instrument Configuration (User Setup)

Important, the unit must already be switched on for transferring the above mentioned
data. Only then can the connection cable be hooked up to the PC.

The unit needs to be switched to the Main Setup Menu for transfer. There are a number of
PC programs on the market which allow communication with the Flytec 5030 GPS. The data
transfer for the On Line Contest for the DHV is, however, only possible with the full version
of FLYCHART, or by using one of the programmes listed below;

For Laptops without serial interface COM1 you need to use a Serial to USB Adapter. Flytec
can only support the USB Adapter from Flytec. It works fine with Flychart 4.50 and higher.
Please don’t forget to install the Adapter Driver delivered on the CD.

Note: This adapter works only with Flychart. It is not possible to use a USB Adapter to
update the firmware.

Additional programs which permit data transfer with our unit:

4.2 Transferring New Software to the Flytec 5030 GPS

As is the case with many other new developments, improvements or add-ons come
afterwards. The FLYTEC Company will place programme updates from time to time on our
FLYTEC homepage on the internet, which can be downloaded by the user free of charge,
saved and then transferred to the Flytec 5030 GPS. ( actual now is Version 2.16 )
In order to be able to write to Flytec 5030 GPS's flash memory at all with one's own PC, a
software tool is necessary, which is a compressed file named “Flash 5030.zip” (approx.
1MB). In addition, the actual firmware programme to be transferred must be obtained from
the home page. It is called “5030v221.hec” (approx. 400 KB) which corresponds to the
version 2.21.

We recommend that you store all the related files in one separate subdirectory. After
decompressing the ZIP file a number of files are created. Double clicking on the file
“uploader. exe” starts the program. Under “Setup” the serial port (COM1 or COM2) can be
chosen. Under File / Open upload file you select the file to be transferred with the extension
“.hec” . Now it is time to plug in the cable into the switched off Flytec 5030 GPS. By
pressing on the “Open” or the “Upload” key the data transfer starts automatically.

Important: Contrary to the data transfer of waypoints or routes be sure that the 5030
GPS is turned off when plugging the cable into the computer.

Note: Never leave the PC cable hooked up to the instrument when it is turned off.
If this is done, the Instrument resumes in programming mode energy and the battery
can be drained unnoticed.

It can occur, that the 5030 switches on during plugging in the cable. In this case please
remove the cable, wait until the unit is switched off and connect again.

For Laptops without serial interface COM1 it is not possible to load new firmware into the

5030. Please use a desktop with the appropriate serial interface COM.

5 Appendix

5.1 Stall alarm

If a pilot gradually slows down his/her glider, he/she will cause a stall when falling below a
certain speed, which has different consequences depending on the type of aircraft. If the air
current is suddenly cut off from the entire surface, then a completely unforeseeable crash is
inevitable. For this reason manufacturers are building a so-called cross-setting (washout)
into the support areas of the wings; this means during flight that the wing tips, will always
have a smaller angle of incidence than the middle of the wing. If the air flow stalls in the
middle area of the surface when falling below a minimum speed, then lift still remains on the
wing tips. The aircraft does not enter a deep stall or incipient spin. Because the wing tips are
situated behind the aircraft's centre of gravity, the wing will drop nose downwards and will try
to recover by gaining speed. It is not advisable to stay long in this flight situation, as the
glider will react very sensitively to even small air turbulence. A stall can be dangerous,
especially during the landing approach. The consequence could be a stall or an incipient
spin. The stall alarm is a loud, concise, acoustic signal that tells the pilot to fly faster. It
assists, first and foremost, hang gliders and paragliders but the latter to a lesser extent.
Anyone who has ever watched a hang glider come in during an approach can observe the
following: when a good headwind prevails, many pilots will pull out their steering bar too
early; the glider climbs a few more meters so that, in a favourable case, it ends up with the
keel stuck in the ground. With no wind or with a light tail wind most pilots wait too long to
pull out the bar. With luck the result is only a belly landing, but the result can also be ground­loop with broken base side tubes, or the glider's nose absorbs the impact, causing the pilot
to swing like a pendulum, hitting his helmet on the front keel tube.
Different stall speeds apply for varying wing loads and pilot weights. Several tests to
determine your own speed are necessary for setting your correct stall alarm limit in the
Setup menu. It is worth noting that close to the ground, because of the air cushion under the
wings, the stall occurs at approximately 2 km/h lower speeds than in free air. On our own
gliders the correct setting has always been between 30 and 34 km/h. The stall speed also
depends on the specific weight of the air at different altitudes. In the Flytec 5030 GPS the
level for the stall alarm is automatically raised with increasing flight altitude, corresponding
precisely to the indicated airspeed. It makes no difference if the pilot has chosen true or
indicated airspeed for the speed display.
The distance to stall speed is easy to control now.
The limit between stall alarm and the speed for minimal sink is very small. Several pilots
have complained about the fact that while circling up in weak thermals at the speed of
minimal sink, the stall alarm sometimes turns on. For this there is an altitude limit the pilot
can adjust in the Basic Settings / Stallspeed , above which the stall alarm will not be initiated.
The landing areas should then, of course, lie below this limit.
Experience has shown that about half of the otherwise not so wonderfully executed landings
could have been saved by pushing the steer bar upright when the stall alarm turns on.

5.2 Netto vario

In contrast to the normal vario, on which the vertical speed of the glider is shown, a netto
vario indicates the rising and sinking of the surrounding air mass. The prerequisite for this is
a correctly entered polar curve and, of course, a speed sensor. Let's assume that a pilot is
flying at 50 km/h through the air. The Flytec 5030 GPS determines from the polar curve that
at 50 km/h there would be a sink rate of 1.1m/sec expected. In our example, the normal
vario could only show 0.5m/sec. Therefore, the surrounding air has to rise by 0.6m/sec to
reach this pair of values. However, if in our example the normal vario indicates a 2m/sec
sink, then the corresponding air would have to sink by 0.9 m/sec. This means, with the

42/53

Flytec 5030 GPS

correct polar curve and calm air, the netto vario would have to show a value of 0 at all
speeds. Or, the other way around, we are in the position to check our polar curve when we
are certain that the air is absolutely still. If the netto vario here in the upper speed range
indicates air which is continuously rising by 0.3 to 0.5 m/sec, then we know that our wing is
better than the stored polar curve and sinks less than the 0.4 m/sec that the polar curve
states. This can be corrected. ( Basic Settings / Polardata)
What else is the netto vario used for?
Another example from common practice:
A pilot crosses a valley rapidly. Suddenly he/she notices a sharp decrease in sink rate and
turns in instinctively. This was a mistake because the desired climb turns out to be nothing
more than zero lift. A quick glance at the netto vario, which in our case shows 1m/sec rising
air, would have kept him/her from losing time and altitude. The netto vario display only
makes sense during longer descending glides. While climbing in a thermal it is better to
activate the integrated vario, which indicates the average climb over a chosen integration
time period.
If you chose Brutto, Netto Sink the following time apply:
Ascent -> Integration time chosen in the Basic Settings
Netto Sink -> Integration time always 1s

5.3 True or Indicated Airspeed; TAS or lAS

In general aviation it is custom to measure the airspeed with the help of a pitot tube as a
dynamic pressure speed (= IAS) and also to display it as such. The advantage of this
method is that at any altitude level the maximum allowable speed or the stall is marked
(flight safety) at the same position on the scale. This is also the case for the speed of the
best glide (flight performance) at preferred altitudes which have a fixed position on the speed
scale. However, the disadvantage of this system is that the indicated speed is correct only
at a certain altitude (usually at sea level). The glider will fly increasingly faster the higher one
climbs due to air getting thinner, without the indicator picking this up. At approx. 6,500m the
air weighs only half of that at sea level, and the air speed will therefore increase 1.41 times
that ( as a radix of 2). You could picture the physics of it as follows:
In order to create a certain lift, a certain number of air particles have to hit the surface
bearing the weight (wing). Because at an altitude of 6’500m there are now only half as many
particles present per cubic metre, the surface has to fly faster, but not twice as fast because
each particle possesses a higher striking energy, around 41% faster.
However, in calculating wind, arrival altitudes, or arrival times you always require true air
speeds. The wing wheel sensor (propeller sensor) shows the true air speed (=TAS)
because it runs practically without friction.
Thanks to modern processor technology, our Flytec 5030 GPS will always use both speeds
side by side, regardless of which speed input is used or which type of speed is displayed.
The pilot can set the speed he/she would like to see in the display. However, the pilot
shouldn't be surprised if he/she sets the display as IAS, for example, that, at high altitudes
and with calm air, the difference between groundspeed and airspeed will correctly show
zero, although the groundspeed provided by the GPS will be much higher than the indicated
airspeed.

5.4 Polar Curve and Required Speed

The polar curve of a wing is represented as a diagram. It shows the connection between
flying speed and the associated sink rate directly. It provides information about an aircraft's
ability to perform. From the polar curve the minimum sink rate and the associated speed
can be read immediately. If one plots a tangent from zero on the diagram to the polar curve,
it shows the best glide speed in calm air where the points meet. If one divides the speed by
the associated sink rate, the result would yield the best possible glide ratio. (Both values

43/53

Flytec 5030 GPS

naturally have to use the same units).
When the Flytec 5030 GPS is turned on, the polar curve entered is calculated and stored in

the unit's memory as a very precise chart. At every flight speed the unit knows immediately
how strong the associated sink rate should be. If the sink rate measured by the vario,
amounts to more than the charted value, the pilot will find him/herself in sinking air. If, for
example, the vario announces, with the below mentioned paraglider, a sink rate of only

0.5m/sec when flying at 35 km/h, then the pilot needs to be located in air rising at 1.3-0.5=

0.8m/sec; this is also shown by the netto vario. (See 5.2)
Because the Flytec 5030 GPS knows the rise and sink rate of the surrounding air mass, it
can continually plot new tangent lines to the polar curve in order to indicate the speed of the
best glide in any situation.

Polar curve of a high performance hanggliders: Polar curve of a high performance
Paraglider
Best L/D: 47/(3.6x1.2)=10.9 Best L/D: 35/(3.6x1.3)=7.5

In the example for the hang glider above, the dashed line of the tangent is assigned a sink
rate of the air mass of 2m/sec. The required speed related to this is 63 km/h. The required
speed is the speed indicated which allows the pilot to fly constantly at the best possible glide
ratio. He/she will, i.e. arrive higher at a valley crossing than his/her colleagues, who are only
flying according to feel (during the same conditions).
The pilot flies, in the example to the right, much too slowly because he/she stays too long in
the sinking air; he/she will lose both altitude
and time. If the pilot flies faster than the
instrument's recommended speed of 62
km/h, then he/she would arrive lower than
his/her colleague, who is flying at the
optimal speed of 62 km/h. In the paraglider

tangent line is drawn for a head wind of 20

the pilot flies with an activated GPS, then
this increase in the best air speed will
automatically be taken into consideration by

1

the required speed arrow.
In contrast to sailplane gliders for which the manufacturer's measured polar curve has

validity for a long time, with hang gliders and more so with paragliders the polar curve is
dependent on the age of the surface, the condition of the sailcloth, the weight of the pilot,
his/her harness, and other factors. In order to realize the best possible speed during a later
flight, it is necessary to input the polar curve as accurately as possible, which means, it
should be determined by the pilot. It is obvious that such a measured flight will bring the best
results in stable air conditions.
Particularly interesting are value pairs (speed and its associated sink rate) in the upper third

44/53

Flytec 5030 GPS

of the speed scale, in the area of the best glide and the speed of the minimal sink rate.
(Maximum speed achieves nothing!) Each speed should be maintained evenly over several
seconds. With the aid of FLYCHART- PC program, the data attained can be analyzed and
the polar curve can be determined. This polar curve can now be entered manually into the
Flytec 5030 GPS in the Set Mode.

Two polar curve points only are needed for the input.

1) The velocity (km/h or mph) and the value of the minimum sink rate (m/sec or ft/m).
At this position the polar curve runs horizontally;

2) A pair of values in the upper speed range. (not at max. speed )
It doesn't make sense to mislead yourself; too good a polar curve will, in the end, require a

speed that is too high. Because the input of both polar curve points always result in “true”
values, the middle altitude at which the polar curve was flown has also to be recorded. In
the polar curve chart, which is calculated by the instrument (a value pair for each km/h), all
of the documented polar curve points are converted and saved as “Indicated”. This means
that this polar curve is valid for all altitudes.

5.5 McCready Theory - Optimized Speed to Fly

In contrast to the simple required speed which allows us to reach a goal with the least
possible loss of altitude (which is synonymous with the maximum safety against landing out),
one can get to a goal in the shortest possible time with the help of the McCready theory.
Therefore, competition or record pilots have to deal with this theory. If a pilot finds him/her
self thermalling up in order to approach a goal (that can be a turning point, a landing field, or
even the next thermal source), then he/she must consider whether to leave the thermal as
early as possible in order to reach the goal at best glide, or whether it is better to thermal up
higher in strong lift and then glide with higher speed to goal.
McCready has found that with a given polar curve, there is only one departure altitude that
enables one to reach the goal in the shortest time. This departure altitude is dependent on
the average climb in the thermal and the prevailing wind component. The speed for the final
approach is primarily dependent on the average climb in a thermal.
Because the Flytec 5030 GPS knows all the parameters during thermalling , it can give the
all clear to the pilot to leave the thermal to reach the selected goal as fast as possible.

The unit works, making the presumption that, on the glide path to goal, rising and sinking air
neutralize each other and the wind remains constant. Because these conditions do not
always exist, it is also dependent on experience and care by the pilot to climb to safety
height above the glide path before leaving the thermal. This height above glide path,
determined in advance, is continuously recalculated and displayed. In addition McCready
discovered that, exactly as with speed to fly, the speed of the best glide depends on the
sinking of the surrounding air mass. The same flight speed can also be used for the fastest
possible arrival at your goal if one takes the average lift in a thermal instead of the sinking air
mass. In other words, if the average climb in the last thermal was 2 m/sec, the pilot who will
reach his/her goal first is the one who circles up high enough that best Speed to Fly,
corresponding to a sinking air mass of 2 m/sec, can be flown directly to the goal.

With earlier mechanical vario pilots constructed a ring, which was arranged to swivel around
the circular vario scale. In the centre of this McCready Ring a thick arrow stood opposite the
vario zero point of the vario. (This is the ring position for the best glide.) In the lower half of
the ring, were the required speed recommendations. (in km/h). To use it, the pilot first had to
turn the ring so that the arrow stood opposite the average climb mark on the vario scale.
Next he/she was able to read the recommended speed behind the current vario indication.
Then he/she corrected his flight speed following the recommendation, which of course

45/53

Flytec 5030 GPS

resulted in another vario indication and necessitated another correction.
With the Flytec 5030 GPS, as with the 5000 instrument series, we are entering a new area

for distance optimized Speed to Fly. The pilot does not need to touch the unit to change the
McCready ring value (that is the average thermal climb); but this value will be shown to
him/her as an active McCready indicator, displayed as a single arrow in the climb range of
the vario scale. The indicator goes up when the pilot speeds up, or has less sink. The
indicator goes down when the pilot meets stronger sink or flies slower. How much the value
changes, depends first of all on the polar curve. The pilot has to adjust his/her speed in such
a way that the indicator always stays above the value of the average climb. As the
McCready indicator cannot only be seen, but also its value is conveyed acoustically by
means of a variable tone (pulse/pause=1:4), the pilot does not need to watch the indicator
continuously, but can react to vario changes of the McCready indicator immediately by
adjusting his/her speed to the changing tone.
In order to offer the pilot additional help it is possible to set an acoustic dead band around
the chosen McCready ring value (this is that position of the McCrdy pointer when the user is
activating the McCrdy sound by pressing the key McCr /Mark ) This means, the pilot flies
correct according the McCrdy theory when the instrument is quiet. In the Setup menu Basic
Settings/McCready one can adjust the wideness of this dead band. (Factory setting = + - 30
cm/s)

A Case from Experience:
A pilot is crossing a valley at a relatively high speed. Due to a lot of sinking air, the danger
exists that he/she may not be able to get over the ridge on the other side of the valley. So
that the least amount of height is lost from this point on, he/she will reduce his/her speed
until the McCready indicator is on zero. (This is the speed of the best glide too) And on the
analogue speed scale of the Flytec 5030 GPS, the indicator for best glide will correspond
with the actual present speed. (See picture last page on the right )

If the pilot were to reduce his/her speed even further, the McCready indicator would run into
the negative number range. This is a flight condition which must be avoided, because the
pilot loses both time and altitude unnecessarily.
The Flytec 5030 GPS warns acoustically by a deep tone with rapid intervals, if this flight
condition occurs. This happens mostly when a pilot flies in the area of “Best glide” and then
ends up in sinking air. In this case he/she has to act very quickly.

Since every longer flight consists more or less of a sequence of thermalling up and gliding
away, it is basically unimportant whether the gliding speed conforms with the expected climb

in the next thermal or the climb already achieved in the previous thermals. In order to give
the pilot an indication of the average thermal climb, the grey marked double rim at the
analogue vario displays the average value of the past 10 minutes of climb This value is not
influenced by passing through sinking air.

To fly at an optimized speed, we have to adjust our speed in such a way that the McCready
indicator covers the pointer for the average thermal climb (Picture on the left). Of course
arbitrary deviations from this indication are possible and the decision lies with pilot as to how
these will be assessed. As a rather cautious and conservative pilot, I prefer to fly with the
McCready indicator in a middle position between 0(= best glide) and the shown value for the
average thermal climb.

All the functions described here can be imitated in the simulation mode. The measured
values such as speed, sink or climb, flight direction and also ground speed can be varied by
the user and their effects on the results can be observed on the LCD screen.

5.6 Final Glide Calculation

Here the GPS data and the McCready theory go hand in hand. (Please also read the section

5.5 McCready Theory) Principally it is about reaching a goal as fast as possible (of course it
has to be logged as a waypoint in the list), or rather, to get a signal from the flight instrument
of when the last thermal can be left to arrive at the WP as fast as possible. To be able to
make a decision about this, the distance to this location (goal/waypoint) has to be known.
The distance is calculated with the help of the GPS receiver. Additionally we require the
altitude of the waypoint (is in the WP list) and the present altitude of the pilot. From this
information the required glide ratio over ground (L/D req) that is necessary to reach the goal
can be calculated. All other conditions such as wind and wind direction, flight speed and
polar curve are not considered. The required glide ratio can be shown in the user defined
fields: LID req. Only when the flyable glide ratio (over ground) has to be calculated do the
conditions just mentioned, play a role.

Basically the final glide (final approach) consists of two phases, to be considered separately:

1) Climbing in the last thermal

2) The straightest possible glide path to goal

1) Let's assume that our pilot is circling under a cloud in a very good thermal, which

provides him/her with an average climb of 2 m/sec. While circling he/she will naturally try
to fly with the speed for minimum sink. Besides the polar curve table in the Flytec 5030
GPS's memory, there is a second table calculated S2F (speed to fly), which knows the
associated McCready speed for each average climb (30 sec average) in a thermal. To
this belongs a glide ratio (through the air). If, while circling, the nose of the aircraft turns
again and again in the direction of goal, the wind component and the glide ratio over
ground can also be calculated at that moment.
A zero wind has a wind factor =1; Tail wind >1; and Head wind <1. From the distance to
goal and the glide ratio (over gnd) the Flytec 5030 GPS calculates the altitude which the
pilot will lose on his/her glide path to goal. If we also add the altitude of the goal, (input
for each waypoint) then we obtain the optimum departure altitude.
One's own altitude is known; therefore, the flight instrument can tell by comparison (in
the display Alt. over WP) whether we still have to thermal up to arrive at the fastest, or
whether we are already above the fastest glide path. Of course it depends on the
experience of the pilot whether he/she wants to leave immediately during a positive Alt.
ov.WP indication, or to climb up further and take some reserve altitude. The Flytec 5030
GPS naturally does not know whether in the course of the glide path, lifting or sinking air

47/53

Flytec 5030 GPS

masses have settled, or whether the wind will change. It takes into account the present
wind and assumes that no rising or sinking air masses will be encountered.

2) Gliding to Goal

Our pilot has left the thermal at the moment when the Flytec 5030 GPS shows Alt a. WP
= 0 and is flying towards his/her goal. He/she should speed up until the pre-calculated
altitude over the goal is at 0 again. His/her McCready Indicator will be around 2m/sec.
(In our example, he/she is now flying at approx. 62km/h.) He/she can even cross an
area of sink, but will have to fly afterwards with a smaller McCready ring value. Under no
circumstances should he/she allow the McCready arrow to go below 0. This means that
with good lift in a thermal, before the departure to goal, certain altitude reserves exist
because of the higher speed. If the average lift is small, the unit calculates with a glide
speed just a little more than the one for the best glide; there are practically no altitude
reserves and a small area of sink can force the pilot to land before reaching goal. In this
case one should, before leaving the thermal, increase the safety altitude by 'tanking up'.

5.6.1 Safety Altitude ( = Alt above BG )

The display ‘Alt a.BG ‘ indicates the pilot's current altitude above (or below) the best glide
path that leads to goal. The Alt a.BG is also the altitude which he/she can safely lose when a
sinking air mass is encountered during flight and still make it to goal.
The Alt a.BG can be continuously shown in the user selected fields; it is identical with
Alt a. WP when the pilot flies with the best glide speed.
The fields Alt a.BG and Alt a.WP will switch to invers display when become positive values
during thermal circling. This information allows the pilot to leave the thermal to reach just the
goal ( Alt a.BG ) or to reach the chosen WP with fastest glide (Alt a.WP )
See lower pic. Chapter 2.7 Goto.

5.6.2 Final glide calculation with several Waypoints in between

With this Version 2.21 we've added a new User field: Alt ab.Goal . Based on the best speed
of glide, this is a precalculation of required height gains over all sectors of a route in front of
the pilot to reach the goal (= the last WP of the route) . For each sector the belonging wind
component is taken into account. Do to so the actual wind vector is used. This wind vector
will be actualized always, when flying a full circle. Of course, the instrument does not know
any future changes of wind.

5.6.3 Manual Windcomponent

In all our considerations up to now, the windcomponent Spd-Diff ( groundspeed - airspeed )
had been calculated automatically. There are some valid reasons instead of using this
automatic calculated value to overwrite the internal windcomponent which is responsible for
all speed to fly and final glide calculations with a fix manual input value.

1. The true wind outside a thermal always is stronger as the automatic detected wind by
the instrument during circling up. How much stronger depends on the vertical speed
of the thermal and if the pilot has already reached the thermals upper end. It is up to
the pilots experience to enter manually a certain head- or tailwind.

2. During a final glide even small wind fluctuations ( also evoked by yawing) can cause
differences of the precalculated arrival altitude. A manual input windcomponent will
keep the result more stable.

3. A pilot flying in high altitudes knows by experience how the wind in lower stratums
will change. He can take this into account in due time.

To enter manually the wind component press briefly F1 ( next function) until HT wind = auto
shows up. With the up / down keys your desired value can be set. But be aware: Don't forget
to change back to automatic wind component when changing your flight direction.

5.7 TEC Total Energy Compensation

What's the meaning behind this expression? Is this valid for sailplanes and what can hang
gliders and paragliders do with it? If a cyclist rides up a small hill without pedalling, it
becomes clear to everyone that he/she gained this difference in altitude from his own
momentum. It is precisely this which the TEC explains; he/she converted his/her kinetic
energy into height. If he/she rides down the hill again, the exact opposite happens; he/she
converts the altitude into speed (distance). His/her total energy remains constant. For pilots
the same applies.
If obvious gain in altitude can be achieved by excess speed reduction, the use of TEC
always makes sense. A hang glider can well gain 20 or more metres of height when pushing
out the steer bar at high speed. It would be a big mistake if this altitude gain were shown by
the vario and would even perhaps tempt the pilot to turn. A good flight instrument can

50/53

Flytec 5030 GPS

suppress these vario swings caused by speed changes. A vario is only supposed to indicate
climb or sink caused by the surrounding air and not by conversion of speed to altitude.

When flying according to Speed to Fly, where speed adjustments are continuously
necessary, the TEC is of great help. The TEC also steadies acoustics and vario when
centring in a turbulent thermal. The penetration effect of the TEC can be adjusted in the
Basic Settings/TEC From experience we recommend values between 60 and 80%.
Complete control (100%) has not proved efficient, because even horizontal wind turbulences
can influence the TEC and make the vario a bit jumpy.

5.8 New Regulation for Record Flights or De-centralized Competitions

Since the proof of a completed flight depends entirely on the GPS recording, it is important
to ensure that the GPS receiver receives satellite signals before take off. Please turn on the
Flytec 5030 GPS several minutes at least before take off so that even pre-flight events are
included in the recording. (Please also read 3.2 flight recording)
A barogram is also included in the recorded IGC data of each flight. Photographic proof and
confirmation by flight observers are no longer required for national performance flights. The
data can be sent directly to the judging committee (in Germany the DHV) via Internet. (See
also 4.1 Data Exchange by PC)

5.9 Proof of Flights - Security against Manipulation

The FAI (Féderation Aéronautique Internationale) and its subsidiary IGC (International
Gliding Committee) requires a recording format, which, besides the continuous recording of
time, and position, also includes the flight altitude. In so doing it replaces the standard
barograph. When transmitting flight data to the pilot's PC, a so-called IGC file is created,
which receives a digital signature authenticating the flight data, making the file fraud proof. If
only one bit in the flight data were changed, the signature would no longer correspond, and
the judging committee would be aware of the manipulation.

5.10 Digital Signature and OLC `Registration

The constantly growing popularity of decentralized competitions is still going on. Up to now,
26 countries have signed the new agreements. (Online Contest) These agreements state
that every flight submitted via the internet, has to follow the IGC format and must have a
digital signature. All flights have to be recorded in WGS84 map data format. Therefore, from
now on we support only WGS84.

In order that GPS receivers generally available on the market can be used, relevant
evaluation programmes like Compegps, Gpsvar, Maxpunkte or Seeyou calculate a digital
signature to allow submission of flights in the desired form. However, a signature created by
a PC provides limited safety against manipulation . Looking further ahead this signature will
most certainly have to come from the GPS data logger.

At the automatically or manually end of a flight this digital signature is created, , in the Flytec
5030 GPS and added to the logger's memory as a so called G- record. A message is
displayed “Generating Digital Signature” in the Info Field of the instrument. As this
calculation is very demanding it may take several minutes following a long flight with a short
scan rate set. Please wait until the relevant display disappears.

In case the OLC does not accept the flight data which were sent , call up again the
Flight - Analysis and recalculate the digital signature again by brief press of F2

6 Miscellaneous

6.1 Landing on Water

If you are forced to land on water, water can enter the instrument. However, there is a
chance to save the instrument or at least parts of it. Once water has entered the GPS
module it is definitely lost.

To save other parts proceed as follows:
a) Open the instrument at once.
b) Pull off the red Jumper lead next to the

beeper connection cable. This separates
the circuit from the power supply (see
picture).

c) If the landing was on salt water – rinse the

circuit board and all areas affected, with
clean, fresh water. Dry the instrument
carefully with warm air. (Hair dryer)

d) It is also recommended that the flat key-

pad cable is removed.

e) Return the instrument to FLYTEC for readjustment and a final check.

The guarantee is void after a Water Landing.

6.2 Guarantee and liability

Our instruments carry a 24-month guarantee. However, physical damage such as a broken
casing or glass breakage as well as damage resulting from water landings are excluded from
this guarantee. Flytec can accept no liability for faults arising from any abuse or unapproved
use of your instruments.

WARNING
In very rare cases it can happen that a flight instrument does not provide any data at all or

the data is incorrect. FLYTEC AG will not be held responsible for accepting any damage
claims arising from a malfunctioning unit. Responsibility for ensuring the safe execution of
his/her flights lies with the pilot alone.
