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:

Normal Paraglider High Performance

Hang Glider

Performance

Hang Glider
5-7 7+ 8-10 11-14 15+
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

1.8.11 XT Error, Crosstrack Error

This userfield shows the shortest distance (Perpendicular on a map) to the active leg of a
route

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
line is indicated (see position 3)

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
