F2: Zoom in: The map scale is gradually increased to approx. 0.5-1.0km. Thus, individual

circles during a climbing period are clearly recognizable
(This is dependent on the set recording interval).

F1: Zoom out: The map scale is gradually decreased until the screen display is optimized.
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.

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

This function is only enabled in flight memory mode. During flight, the actual position is in the
center of the map. If the position reaches a border, the map pans automatic.

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 the flight, touching the ESC key briefly will bring you a real-time track and map
display. Vario and height appear digitally under the map. For competition 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.

The example shows an aircraft with lift/drag ratio 8. The necessary lift/drag ratio to the goal
is 6.3. The aircraft symbol is around 2.3 units above the point of best glide.
The strategy is, to hold the symbol in the crossover during the final glide. In order to hold
something reserve, experienced pilots will fly rather above the point of best gliding. During
thermalling the symbol remains in the center. As long as the deviation is larger than approx.
20 lift/drag ratios, the symbol appears grey in the center. Below that margin, the symbol
disappears to approximately 20 lift/drag ratios deviation. With approximately 6 lift/drag ratio it
appears then again from down in the window. If it comes upward over the delimitation, it
appears again grey.
A small arrow appears ^ above with the increase as a heading assistance, if track and
bearing are within +/- 10°. When sinking the arrows < ^ > indicate a recommendation, where
one should hold. If the symbol leaves the range of approximately plus minus 60°, the symbol
is grey again. One should switch then with the Esc key to the Vario screen, in order to see
the compass with the direction markers.

A series of settings permit the unit to be programmed according to the user’s wishes. Every
pilot can realize his/her own ideas. If too much information bogs you down and causes
confusion, it is always possible to reset the unit at Basic Settings/ Init EEPROM, which are
the manufacturer’s tested basic settings. You are basically starting again.

But please note! All WP and routes will be a deleted too. As a minimum, settings possible

and default values set will be shown at the setting points. Should these values be changed,
you move to the change mode by pressing Enter. The value to be changed will blink and can
be modified with the help of the ▼ and ▲ keys. Pressing the Enter key confirms the new
value. Pressing the ESC key recalls the previous setting.

1.9 Battery management

Two bar graph scales indicate the capacity of the batteries. The Flytec 5020 has 2 banks
with 2 batteries each. Bank 1 must always be equipped. Bank 2 can remain free. However,
we recommend to equip bank 2 also. As soon as the first bank is used up, the instrument
switches automatically to the second bank. If the second bank is not yet used up, and bank 1
is equipped with new batteries, the instrument switches to the first bank again. After a long
flight we recommend to insert the partly used batteries of the bank 2 into bank 1 and to equip
bank 2 with new batteries. Thus it is ensured that the instrument can use up the batteries
always completely, without the danger of having empty batteries during a flight. Before S/N
5500 the two banks in the battery compartment where changed.

The following battery types could be used
2 pieces per bank Alkaline High Power Batteries 1.5 Size AA. Estimated life time 2 * 13h =
26 h together (recommended types: VARTA or Duracell)
2 pieces per bank NiMH Accu 2100mAh, 1.2V Size AA. Estimated life time 2 * 11h = 22h
together. The bargraph shows only the actual battery voltage, not the capacity.
We don’t recommend NiCd Accu because they have clearly smaller capacities and are not
pollution free. The battery thresholds are optimized for NiMH Accus.
Please dispose of the batteries properly.

The estimated life time bases on normal temperature conditions. If the batteries are hotter or
colder they have another capacity, and therefore another life time. The bargraph shows only
the actual battery voltage, not the capacity.

The inserted battery type is not recognized automatically. Because the battery types have
different voltages and a different temperature behavior, the battery type must be entered into
the basic Settings. If the wrong battery type is specified, it is possible that the instrument
switches off during switching between bank 1 and bank 2.

1.10 Data Exchange Via PC

The 5020’s basic equipment includes a data cable for a serial PC interface (9 pol Sub D
plug). Data transfer can occur in both directions. The connection occurs with: 57.600 baud; 1
startbit; 8 databit; 1 stopbit; no parity, Xon/Xoff

- 7 -

Flytec 5020 technical manual

The following can be read via this RS232 interface:

Serial numbers and pilot names
Waypoint list
Route list
A selected flight (track)
CTRs, restricted areas

The following can be uploaded to the 5020:
Waypoints and routes

Important: the unit must first be switched on before plugging in the connection cable to the
unit and the computer.

Before you transfer the waypoints and route data switch the 5020 to the Setup Menu. You
should make sure that the waypoints show up in the unit’s waypoint list before you transfer a
route from your computer.
If you wish to download flight data, switch the unit to the Flight memory mode, and display

the desired flight on the Flight Analysis screen before transferring it to your computer. There

are a number of PC programs on the market that allow communication with the 5020.
We recommend the program Flychart which you can download from the Flytec Website

www.flytec.ch

Other programs that permit data transfer with the 5020:

Trackview (Freeware) Daniel Zuppinger (for OLC und CCC)
Compe-GPS www.compegps.com
Seeyou Program well liked by sailplane pilots www.seeyou.ws
Maxpunkte Free program from DHV for reading flight data for evaluation

and submission to OLC.

1.11 Transferring New Firmware to the 5020

As is the case with many other new developments, particularly during the introduction phase,
improvements or feature enhancements may be expected. Periodically Flytec will post
firmware updates at www.flytec.ch, which can be downloaded by the user free of charge, and
then uploaded to the 5020.

To be able to write to the 5020’s flash memory with a PC, it is necessary to use a
compressed file named “Flasher.exe” that is available in zipped form flasher.zip. In addition,
the actual firmware to be uploaded must be obtained. It is called “5020vxxx.moc” which
corresponds to the version X.XX. Both of these are available from the download page at
www.flytec.ch
We recommend that you store all the related files in a separate subdirectory. (e.g.
c:\programs\FlytecFlasher\). After decompressing the ZIP file a number of files are created.
Double clicking on the file “flasher.exe” starts the program. Under “Setup”, the serial port
(COM1 or COM2) can be chosen. You select the file to be transferred with the extension
“.moc” by pressing on the “Start” key. The data transfer starts automatically. The numbers
shown on the right side are the answers of the instrument.

Flytec 5020 technical manual

Sometimes the Flasher will give an error. In this case, the cable must be unplugged, and the
5020 turned off before making another attempt to flash the memory.

Important: Contrary to the instructions for data transfer of waypoints or routes, be sure

that the 5020 is turned off when plugging the cable into the computer and the 5020.

Important: Never leave the PC cable hooked up to the unit when it is turned off. If this is

done energy is consumed, and the battery can be drained.

5 Analog Vario

The resolution of analogue vario is 40 fpm or 0.2 m/s.
The first full-scale range is from +/- 0 to 800 fpm (+/-4 m/s) after which the display switches
automatically to a second range from 800 to 2000 fpm (4 to 10 m/s).

The time interval (damping) over which the measured climb rates are averaged for the

analogue (and associated sounds) is factory set at 1.2 seconds. This can be changed to any
value between 0.6 sec and 4 sec. in Menu/Basic Settings/Vario-Speed-Average. If the time
interval is too short, the vario is very twitchy; if too long, it’s rather sluggish. A lower
dampening value is preferable for smooth light conditions. A greater dampening value may
be desirable in rough turbulent conditions. Note: This setting should not be confused with
vario integration (averager) that can be set for the digital vario display.

A small pre filter can be adjusted to be used as a turbulence filter. It can be adjusted from

0.1s to 1 s. (Settings 1 to 10)

5.1 Altimeter and Air Pressure

The Flytec 5020 has 3 altitude displays.

Alt1 is always the altitude above sea level (QNH).
Alt2 is a reference height; it can be altered or zeroed at any time

Press F1 several times until „Mod A2“ appears. The arrow keys change A2.
F2 resets A2 to zero.

Alt3 cumulates the gained height over one flight
Among the user selectable fields 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. he 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

If Alt1 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.



5.2 Acoustics and Volume Level

In the acoustic menu, most of the parameters can be set to fulfill most of the pilots wishes.

Each time the key /Route 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.

- 11 -

Flytec 5020 technical manual

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’.

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 0.2m/s to 0.4m/s.

Asc. F

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

when it is suppressed at the starting point.

Mod.

Modulation (see graphic below)

Pit.

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

- 12 -

Flytec 5020 technical manual

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.

Sink tone thres.

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

can also be choisen during flight with the F1 key “Nxt Fnc”. If this

function is avtivated, the sink tone threshold can be adjusted with the

S /T keys. With F2 „SNK OFF“ or „SNK ON“ it is possible to switch

on or off the sink tone. If the sink tone is activated, there is „SNK OFF

visible and the sink tone can be switched off by pressing F2. If the sink

tone is switched off, „SNK ON“ is visible and the sink tone can be

switched on with the F2 key.

SinkF

Sink tone/alarm The basic tone deepens when sink increases. It cannot be set
Frequecy base to a higher frequency than the climb acoustic frequency.

The basic tone acoustic may be set lower.

The warning tone for stall alarm is a midrange tone with a fast interval and full volume.

All this settings can be controlled in simulation mode.

All of these settings can be tested in simulation mode.
If a low and quiet random noise can be heard at the beeper, even if it is set to 0%, this is a
normal effect of operation.

5.3 Digital Vario

The digital vario has a resolution of 10 cm/s (20 ft/m) and a very wide measuring range of +/-

70 m/s.

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.

6 Speed

The 5020 has an input for a vane wheel speed sensor. It shows the true air speed and
begins to make correct measurements above 1km/h; it is also well-suited in determining the

wind strength at take-off. In the Basic Settings > Speed Correction vane it is possible to

calibrate the displayed speed from 70% to 150% (default is 100%).

The wind wheel sensor measures the true air speed. True air speed = TAS.
Speed readings are only in digital displays.

Many paraglider pilots fly without a speed sensor. In this case we recommend displaying only
the GPS-Speed (ground speed). From SW Version 1.12 up it is possible to display the Air
Speed, even when flying without the vane sensor. The value is found by a vector addition of
Gnd Spd and Wind. To get the wind in strength and direction, the pilot has to fly a full circle
regularly.

6.1 Stall Alarm

This Alarm is audible, consisting of short beeps with 100% volume.

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.

7 GPS Functions

The use of GPS receivers has become indispensable for navigation today. A chain of
satellites circles the Earth. It is possible to determine your position very precisely anywhere
in the world by receiving several satellites at the same time.

7.1 Assessment of Reception Quality

The integrated GPS Receiver 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. For
competition flights its always nescessery to have 3D positioning 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.
The instrument looses the Almanc if both battery banks are removed.

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
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 Compeo 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 5020.

Together with the navigation signal, information about the number of received satellites is
shown on the right side of the bar scale. One angle is equal to one satellite with good
reception. The longer the bar, the better is the reception.

7.2 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

- 14 -

Flytec 5020 technical manual

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.

7.3 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.

7.4 Groundspeed

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.

7.5 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.

- 15 -

Flytec 5020 technical manual

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.

• Required glide ratio in order to reach the goal of an active route, from the present

position.
L/D r.Gl. = Distance to the goal over the next waypoints of a route divided by the height
difference to the waypoint. This userfield is only active if a route is active. With this L/D the
pilot can decide if he would fly directly to the goal or if he need to take altitude in a thermal.
The calculation does not take into account if one ore more waypoints between the actual
position and goal are higher than the direct beam from the actual position into goal. The
distance to goal is calculated as described in chapter 7.10.

7.6 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 5020
takes the wind into consideration when calculating the final glide. (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 Goto function.) The calculated wind speed can be displayed in a user
selectable field.

Note: If the wind sack covers the wind directions N E S or W, the letter disappears.

- 16 -

Flytec 5020 technical manual

7.7 Wind Direction and Strength

It is very important to know the wind direction and strength
before an out landing.
The wind strength can be selected within the user defined
fields. It is necessary to fly one or two complete circles as
steadily as possible. Whilst circling, the Flytec 5020
determines the wind direction and strength. The calculated
wind speed can be displayed in a user selectable field.

The instrument calculates the wind from the difference
between Airspeed and Groundspeed. Wind direction is shown
in the compass rose by a small windsock. During the landing
approach this symbol must always be at the top.

7.8 Waypoints and Co-ordinates

A waypoint is any single point on the earth’s surface that you would like to go to. The Flytec
5020 can save up to 200 different waypoints. Each waypoint can have up to 16 characters,

e.g. “Laber Airfield”. In determining the waypoint, it is also necessary to enter the altitude,
i.e. “1865” meters above sea level. We still need the waypoint co-ordinates. (Please also

refer to C3 Waypoints — Alter, Delete or Add.)
For this the Flytec 5020 utilizes the most international and commonly used geographical

maps with the name WGS84 (World Geodetic System 1984). This reference 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).
UTM and Swiss Grid are also possible.
The Flytec 5020 also understands waypoints entered according to the standardized

convention of using 3 letters and 3 numbers. (Created by Brauniger) Example: LAB167
indicates a waypoint with the name LABxxx and an altitude of 1670 metres amsl.

In Basic settings/Coordinate format one chooses the following Input or Display formats

1) Degrees Minutes Decimal places of minutes dd°mm.mmm

2) Degrees Minutes Seconds dd°mm’ss”

3) Degrees Decimal places of degrees dd.ddddd

4) UTM ( a grid with a 1km raster in both E-W and N-S direction )

5) Swiss grid

Basically one should always try to use Nr 1) (=factory setting) because only this format is
using exactly the same calculation format as the GPS receivers do and guaranty the highest
accuracy. With the other formats rounding errors could sum up to 15 m in worst case.
The instrument calculates positions only in the WGS84 geodetic system. It is not possible to
chose other geodetic datii.

7.8.1 Waypoints - Alter, Delete, or Add

Waypoints can be managed at this location of the Main Setup
Menu. Waypoints can be managed very easy with Flychart 4.52
on the PC.

After briefly pressing the Enter key the display shows the list of

logged waypoints (WPs).
All WPs are arranged in alphabetical order.
If this list contains more than 6 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
are now shown, and so on. You can select an individual WP with
the

 or  keys, and edit it by pressing the Enter key.

The first letter of the WP name will blink; again with the

arrow; WP 7 to 12

 and

 arrow keys you can select 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
16 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 Co-ordinate-

Format 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 5020 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 5020.

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

7.8.3 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 “ Goto-Function”)

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

7.8.4 Distance to goal

This userfield shows the distance between the actual position and goal calculated over the
next waypoints in a route.

7.8.5 Distance to the waypoint cylinder radius

To ease the decision, when to turn and head for the next waypoint in a competition route, the
distance to the cylinder radius can be showed as user selectable field. This is specially useful
with starcylinders, because the pilot does not always remember the actual radius of the
startcylinder.

7.8.6 Distance to Takeoff

The same applies for the distance to the start place. The instrument stores the coordinates of
the point when it recognizes a valid flight. Flight recognition is performed if the speed is more
then 10km/h for at least 5 seconds. This is normally valid near the start place

7.8.7 Saving the Current Position

for 3 seconds. As confirmation you will hear a double peep and
those current co-ordinates will be stored in the memory as a waypoint and displayed in the
two bottom lines. The Flytec 5020 uses the letter M (for marker) for the waypoint designation
and then the date and time.

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”.

Flytec 5020 technical manual

7.9 Goto—Function

Prolonged pressure on the Enter/Goto key switches the

lower half of the display into the ‘Goto’ mode. This function
allows you to search for a waypoint stored in the memory of
the Flytec 5020 and choose it for a flight to goal. At the same
time the next five waypoints are listed in alphabetical order.
The number after the WPs names indicates the distance in
km, the 2. number shows the direction to WP (Bearing). After

pressing the F1 (Displ.AIti.) key the precalculated arrival
altitudes to the 5 WPs are shown in place of distance.
In practice there are 5 final approach (final glide) calculations

to the WPs made at the same time.

Note: Only the WP the pilot is directly flying to ( ±/20

degrees ) , the wind component is taken into consideration
for the calculation.

Key Fl (Displ. dist) switches back to the distances. If you

search for a WP with the

Enter is pressed. The Goto function can be deactivated with
the key F2 (Cancel Goto).

The big black arrow in the center of the compass is pointing
directly towards goal.

If a strong cross wind is encountered on the way to goal, the correct angle between the
destination and the wind can be found as long as one carefully changes the direction of flight
against the wind, until the directional pointer in the compass rose points directly upwards.
The large arrow in the compass will now look like the one at the title foto. By doing this you
can be sure that the flight path over ground is in a straight line to goal and thereby the
shortest one. The well known “pursuit curve”’ is thus avoided.

Also amongst the user-selected displays is the safety height above the best glide path (Alt a.
BG). While circling upwards before approaching the WP, this height will show 0 when the
pilot should be able to reach the goal by flying at the best glide speed. Every meter above
that means a greater safety margin.
The Alt a. BG then shows how much ‘security height’ the pilot will have available to use if
necessary in order to compensate for unexpected sink. Under no circumstances should the
pilot go ahead and fly towards goal if the Alt a. BG (Height) shows zero or negative numbers
(reaching goal would then be impossible without finding lift on the way).

Flytec 5020 technical manual

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 and at times he/she may be
high enough to jump a waypoint on a route, while at another time he/she may have already
found a thermal several kilometers before reaching the waypoint.
Of course there is still the option of looking up other, possibly closer, waypoints without
leaving the current route by using the Goto function. Altogether, the Flytec 5020 can have up
to 20 routes set. The same waypoint can be used more than once along a route, and the
same waypoint may occur on other routes as well. Once a waypoint has been used along a
route, it cannot be deleted from the list.

From version 1.12 on, it is possible
to display the user field Dist Gl .
This is the distance over the all
remaining waypoints, calculated
from the actual position.
Additionally it is possible to show the

Altitude above Goal Alt a. Gl in a

user field. This calculation takes the
windspeed and direction into
account, which was derived from
flying one full circle.
It will be assumed that the pilot flies on the track between the following waypoints. To the
next waypoint, the instrument calculates the direct way to this waypoint. It will be also
assumed, that the pilot flies with his best glide ratio. With this two assumptions, it is only the
approximate height above goal because the instrument cannot know the precise wind
conditions and how the pilot flies the way to goal. But it can be a help to fix the strategy.

Direction arrow to the next waypoint:

In the middle of the compass rose a thick black arrow points to
the next waypoint
The arrow to the over next waypoint is a shaded arrow behind

With less effort Routes can be transferred with the program
Flychart 4.52 or others from your PC to the Flytec 5020.
Routes saved in the Flytec 5020 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 5020’s memory). If a WP is
used in a route, then it can no longer be deleted.

7.11.1 Setting a New Route

time you see the request: Select Waypoint No1. Again by using the

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.

7.12 The Competition Route

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 warned by an acoustic alarm when crossing the
circumference of a turn point 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

For the Start Cylinder, the user chooses if the race begins by “Entering or Exiting” the
cylinder circumference. For each of the WPs in the Competition Route, a different cylinder­radius can be assigned (20m … 200km). There is also a count down timer linked with the
Start Cylinder. This lets the pilot know exactly how many minutes and seconds are left until
the window is open. It is possible to use the same waypoint several times (e.g. the goal and
the landing place) with different radii. If the competition route is empty it can not be activated

. The same key is used to assign the status “Start Cylinder” to one of the waypoints.

7.13 Flying a competition route

Because Flytec 5020’s GPS receiver confirms its new position every second, it only takes
one second for the pilot to know that he/she is crossing the cylinder circumference. In this

case a long, unmistakable tone lasting 2 seconds (CMP-Sound) and the unit automatically

switches to the next route waypoint. It is guaranteed that several track log points within the

- 23 -

Flytec 5020 technical manual

cylinder are stored at one second intervals in the memory of the Flytec 5020, totally
independent of what recording interval is used during a standard flight.

Usually the Start cylinder is the first position of the
competition route. (not mandatory) If during setting or

changing the route, the
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 the 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.

If in a competition a start cylinderand start time is defined, the start is valid if the start time is
reached and the following conditions are valid:
Startmode EXIT: If the pilot crosses the radius from inside to outside
Startmode ENTER: If th epilot crosses the radius from outside to inside.

In Version 1.16, multiple start gates can be chosen:

It is now possible to set multiple start times in the Competition Route. Multiple start gates are

only possible if they are evenly spaced. The number of gates and the interval must be
specified (along with the first start and the start cylinder size) when the start point is defined

in Competition Route. In the example below there are 3 starts gates with the first start at

12:30 followed by 12:45 and 13:00 start gates.

EXIT cylinder:

When the Competition Route is set as an exit start the “waypoint reached“ signal will be

given as soon as the start time is positive (countdown timer) and your position is in the start
cylinder. It will also sound if the start time is positive and the pilot crosses the start cylinder
from outside to inside. In both cases the sound is given to alert you that it is time to go to the
next turnpoint and the next turnpoint will become active (in this case WP2). All calculations
and the direction arrows are now with respect to WP2.

If the pilot wishes to take the next start gate, he must press the Prev WP key. If this soft key
is not visible, it can be brought up by pressing F1 until the bottom line shows Prev/Next WP.
By pressing the Prev WP key the instrument will set the start (WP1) as the active waypoint

and increments the start time by the interval set in the Competition Route. If the last start

If the pilot wishes to take the next start gate, he must press the Prev WP key. If this soft key
is not visible it can be brought up by pressing F1 until the bottom line shows Prev/Next WP.
By pressing the Prev WP key the instrument will set the start (WP1) as the active waypoint

and increments the start time by the interval set in the Competition Route. If the last start

gate time has passed and the pilot presses Prev WP, the instrument will not increment the
start time.

Note: It is required that the first turnpoint after the start cylinder is inside the start cylinder
(normally at the same position).

During a flight with defined starttime the pilot can see at the Info display how many
seconds/minutes are left before the opening of the Start line. The time counter shows

decreasing negativ numbers Only when the time counter has reached 0 and starts to
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
ENTER and the other way round if the mode was EXIT. An unmistakable bleeping sound
occurs and the Flytec 5020 switches automatically to the next WP.
The Dist.to WP always counts the distance from the present pilots position to the centre of
the WP cylinder.

When the pilot has left the Start cylinder and the instrument has switched over to the next
WP, pressing the
WP. This is useful when a pilot wants to break off a task and restart at a later time.

Even during the flight along the Competition route it is possible to select additional waypoints

(thermal sources) by pressing the Goto key (prolonged pressing), sorted according to their

distance from the pilot. The WPs which are part of the Comp. route are marked with an
asterisk in the displayed list; this means they must be over flown. The alarm remains active
when entering a called up waypoint cylinder along the route, even if a waypoint not belonging

to the route has been selected. With the F2 button it is possible to toggle back and forth

between the WP of the Competition route and another WP.

Flytec 5020 technical manual

After completing a flight task, the WP belonging to the Comp. route will be listed in the data
transferred to a PC under the header of the IGC file. A corresponding PC program can also
check if the assigned task was completed correctly.

When setting up a Competition route without a start cylinder and without a Start time, the
automatic switch over to the next WP takes part, as soon as the pilot is inside the 1. cylinder.
So it makes no sense to choose the “Take off” place for the 1.WP because immediately
after receiving satellites the unit switches over to the second WP.

With the Function key F1 one can choose following input
options:

Next ▲pr▼WP = next or previous Waypoint
H/T man. ▲▼ = Manual or automatic* input of wind component (Head/Tailwind)
Mod Alt1 ▲▼ = Modify Alt1 ; (only possible so long no recording takes place )
Mod Alt2 ▲▼ = Modify Alt2
Sink Thresh ▲▼ = Sink acoustic On/Off with F2 or alter with the arrow keys

7.14 Final glide screen and final glide calculations

In the user selectable fields there is a field alt o BG (altitude
above Best Glide). This is the calculated altitude over the path
of best glide. A condition is however that on the way to the
active WP no lifty or sinky air is present, that the wind
considered for the calculation does not change and that the
correct the best lift/drag ratio is entered in the basic settings. If
alt a. BG is positive, then the pilot has a safety altitude to
reach the active WP. If this height is negative, then the pilot
must thermal up the indicated height to reach the goal. See
also chapter 7.10 where a final approach computation over
several WP is described. After repeatedly pressing the key
Esc additional screen appears, which plots the final approach
calculation. A cross hairs shows the path into the goal; a
symbol of a glider the relationship of this the position of the
pilot.

The horizontal scale of the cross hairs shows the difference (As example caused by
shearing winds) between track and bearing to goal. In the example the difference between
the actual track and the bearing is 22° to the right.
The vertical scale shows glide ratios. The cross hairs shows the best glide of the glider which
was set in Basic Settings. The symbol shows the glide ratio (Distance/ Altitude) needed to
goal, corrected by the actual wind. Every tick shows 0,5 L/D.

In the example above the glider has a best glide of 7 which was set in the basic settings. If
the pilot flies on the path of best glide, the symbol is in the cross hairs and Alt. A. BG is zero.
Because his distance to goal is 5,45km his altitude should be %450/7= 780 above goal. Alt a.
BG shows 406 m. He is now 780+406=1186m higher than goal. The l/D required is
5450/1186 = 4,6. The symbol points on this 7-4,6 = 2,4 ticks above cross hairs.

The strategy is, to hold the symbol in the cross hairs. Experienced pilots will hold the symbol
above the cross hairs to have enough margin.

During thermalling, the symbol stays on the vertical axis. If the difference between the actual
L/D and the best glide is more than 20, the symbol is grey and stays in the cross hairs. If L/D
difference is less than 20, the symbol disappears and comes back if the difference is less
than 6. If the symbol goes to the upper margin it will appear grey.

During thermalling there is a small arrow ^ in the upper part, if the difference between track
and bearing is less than +/- 10°. During gliding the arrows <^> recommend in which direction
to head. If the symbol reaches the right or left margin it is greyed out. In this case we
recommend to go back to the vario screen to see the full compass rose including the
direction arrows.

7.15 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. 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 to
the pilot.
In the Basic Settings one can adjust this value between
0,5 .. 3 m/sec . (Last therm.Threshold)

7.16 Restricted Area

It is possible to enter up to 150 restricted airspaces/restricted areas (CTRs) in the 5020.
CTRs will be shown on the real-time map and can be polygons, circles or polygons with arc
sections. The number of possible CTR's depends on the memory available in the instrument
and the unlocked SW-Packages. The maximum number of waypoints for each restricted area

- 27 -

Flytec 5020 technical manual

(top

is 110 waypoints or elements. It is not necessary to duplicate the last waypoint. The 5020
closes the area automatically.

• Without unlocking software packages it is possible to enter up to 20 CTR’s

(depending on the number points required to define the CTR

• With a package release of SW package 02 it is possible to enter up to 150 CTRs

(again depending on the complexity of the CTRs). To use this option software
package 02 must be purchased from Flytec.

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.

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:

Point: End point of a line or arc
Center: Center of an arc
Startboarder: Start point of an arc with direction (+ clockwise/ - counterclockwise)
Stopboarder: End point of an arc (+ clockwise/ - counterclockwise)
Circle: Center of the circle with radius in m

8 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 5020 registers
not only the flight altitude and the flight speed TAS
(= true air speed), but also logs, with the GPS receiver
switched on, the time, position of the pilot in the WGS84
co-ordinate system and the GPS altitude.
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 5020’s memory.
A scan rate of 1 second is advisable for tests or
aerobatic flights. The factory setting is 10 seconds.

It is recommended to use a record interval between 5 and 10 s. Circles are still visible
without producing too much data.. The factory setting is 10s.
For the beginning of a flight the following rule applies:
The start is recognized as soon as the ground or the airspeed reaches at least 10 km/h for
more than 60 seconds or if the altitude difference is more than 30m within 60 seconds. In
each case however, the previous flight history with up to 30 recording points is logged in the
Flytec 5020’s memory.

Flytec 5020 technical manual

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.

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.

Take into account 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 first 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

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.

9.1 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.

9.2 Time and Date

Note: Time, date and year 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

- 30 -

Flytec 5020 technical manual

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.

The date and time will be reset after a power fail of longer than 30s. Please check after you

have changed the batteries.

9.3 Flight time

The take off time is automatically recorded. The clock for the flight time starts as soon as the
speed over the ground or through the air reaches a reasonable flight speed. The flight time
can be displayed in the user selectable fields. The unit will also recognize the end of the
flight. In basic settings you can choose between manual and automatic start and ending of
flight recordings

10 Other functions

10.1 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 and confirms again with „Enter“. Now the simulation starts at the last known GPS

position. With the
and

 arrow keys change the sink or the climb. If the stall alarm sounds, please increase

the airspeed by a few Km/h

The softkey F1 is used to change different functions:
Next Func. var ▲▼ spd ►◄XX
Next Func.wind
Next Func. Mod A1 ▲▼ Modify Alt1
Next Func. Mod A2 ▲▼ Modify Alt2
Next Func. S.Thr –▲▼ Modify threshold of sinkakustik

Next Func. Change page ►

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
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 to ^ you see now, like during a true flight,

how your distance to the last thermal increases, while in the compass rose the symbol ⇧
appears and shows you the direction where the last 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 meters of the waypoint, which tells you,
that you are inside the cylinder. You see the automatic switchover to the next WP too. If a
start time 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 center 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.

10.2 Battery management

Two bar graph scales indicate the capacity of the batteries. The Flytec 5020 has 2 banks
with 2 batteries each. Bank 1 must always be equipped. Bank 2 can remain free. However,
we recommend to equip bank 2 also. As soon as the first bank is used up, the instrument
switches automatically to the second bank. If the second bank is not yet used up, and bank 1
is equipped with new batteries, the instrument switches to the first bank again. After a long
flight we recommend to insert the partly used batteries of the bank 2 into bank 1 and to equip
bank 2 with new batteries. Thus it is ensured that the instrument can use up the batteries
always completely, without the danger of having empty batteries during a flight. Before S/N
5500 the two banks in the battery compartment where changed.

The following battery types could be used
2 pieces per bank Alkaline High Power Batteries 1.5 Size AA. Estimated life time 2 * 13h =
26 h together (recommended types: VARTA or Duracell)
2 pieces per bank NiMH Accu 2100mAh, 1.2V Size AA. Estimated life time 2 * 11h = 22h
together. The bargraph shows only the actual battery voltage, not the capacity.
We don’t recommend NiCd Accu because they have clearly smaller capacities and are not
pollution free. The battery thresholds are optimized for NiMH Accus.

Please dispose of the batteries properly.

The estimated life time bases on normal temperature conditions. If the batteries are hotter or
colder they have another capacity, and therefore another life time. The bargraph shows only
the actual battery voltage, not the capacity.

The inserted battery type is not recognized automatically. Because the battery types have
different voltages and a different temperature behavior, the battery type must be entered into
the basic Settings. If the wrong battery type is specified, it is possible that the instrument
switches off during switching between bank 1 and bank 2.

10.3 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.

10.4 Optional SW- Packages

With the help of a password code (obtainable from the manufacturer), additional special
functions can be activated. For example up to 150 CTR’s.

10.5 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 5020. 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
barogram, variogram, speed gram and course of the flight on a map for later evaluation.
Recently, evaluation programs have been made available which are able to depict the flight
in its appropriate landscape on a computer screen in 3D. In Flychart 4.52 it is possible to
show the flight in 3D on a realistic landscape on Google Earth

10.6 Data Exchange via PC

The 5020’s basic equipment includes a data cable for a serial PC interface (9 pol Sub D
plug). 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 via this RS232 interface:

Serial numbers and pilot names
Waypoint list
Route list
A selected flight (track)
Restricted areas

The following can be uploaded to the 5020:
Waypoints and routes and restricted areas

Important: the unit must first be switched on before plugging in the connection cable to the
unit and the computer.

Before you transfer the waypoints and route data switch the 5020 to the Setup Menu. You
should make sure that the waypoints show up in the unit’s waypoint list before you transfer a
route from your computer.
If you wish to download flight data, switch the unit to the Flight memory mode, and display

the desired flight on the Flight Analysis screen before transferring it to your computer. There

are a number of PC programs on the market that allow communication with the 5020.
We recommend the program Flychart which you can download from the Flytec Website

www.flytec.ch

Other programs that permit data transfer with the 5020:

Trackview (Freeware) Daniel Zuppinger (for OLC und CCC)
Compe-GPS www.compegps.com

10.7 Transferring New Firmware to the 5020

As is the case with many other new developments, particularly during the introduction phase,
improvements or feature enhancements may be expected. Periodically Flytec will post
firmware updates at www.flytec.ch, which can be downloaded by the user free of charge, and
then uploaded to the 5020.

To be able to write to the 5020’s flash memory with a PC, it is necessary to use a
compressed file named “Flasher.exe” that is available in zipped form flasher.zip. In addition,
the actual firmware to be uploaded must be obtained. It is called “5020v113.moc” which
corresponds to the version 1.13. Both of these are available from the download page at
www.flytec.ch
We recommend that you store all the related files in a separate subdirectory. (e.g.
c:\programs\FlytecFlasher\). After decompressing the ZIP file a number of files are created.
Double clicking on the file “flasher.exe” starts the program. Under “Setup”, the serial port
(COM1 or COM2) can be chosen. You select the file to be transferred with the extension
“.moc” by pressing on the “Start” key. The data transfer starts automatically. The numbers
shown on the right side are the answers of the instrument.

Sometimes the Flasher will give an error. In this case, the cable must be unplugged, and the
5020 turned off before making another attempt to flash the memory.

Important: Contrary to the instructions for data transfer of waypoints or routes, be sure

that the 5020 is turned off when plugging the cable into the computer and the 5020.

Important: Never leave the PC cable hooked up to the unit when it is turned off. If this is

done ener

is consumed, and the battery can be drained.

11 Landing in Water

If you are forced to land in water it may enter the instrument. There is still a chance,
however, to save it (or at least some of its parts). Once water has entered the GPS module it
is definitely destroyed.

• The proper procedure is as follows: Take out all batteries.

• Open the instrument case at once.

If the landing is in salt water, rinse the circuit board and all areas affected with clean, fresh
water. Dry the instrument carefully with warm air (hair dryer).
It is also recommended that the flexible cable of the keypad be removed.
Return the instrument to Flytec AG for a readjustment and a final check over.

The guarantee is void after a Water Landing.

12 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 AG 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 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.
