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.

horizontal scale shows the deviation between current track and bearing (the direction to the
goal). 1 division line is 10°, between two large lines is 20°. The vertical scale shows the
deviation of the necessary lift/drag ratio to the goal by the number of best glide of the aircraft,
which will is set in the basic Settings. A division line corresponds to 0,5 lift/drag ratio.
Between two large division lines is 1 lift/drag ratio.

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.

Flytec 5020 technical manual
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.
