Arrow keys:
During the flight one can blank out by use of the right arrow key all waypoints not being part
of the Route. When having left the map screen and subsequently switches back, however
all waypoints shall be displayed again.
During the flight the current position is shown in the centre. The screen moves by half when
the current position is getting to the frame, or when one returns to map mode from any other
screen display.
When viewing a flight stored in the flight memory, the displayed frame can be shifted to the
top, to the bottom, or to the right or left. This function is not enabled during flight.
Note:
Each screen layout may take several seconds, depending on the amount of data. The more
track points are already stored in memory, the more time for screen layout is required.
If during screen layout a zoom- or pan key is actuated, then the momentary screen layout
will be cut short and start over again with the new values. Thus the desired graph will be
reached speedily. The track is redrawn back from the current position. This may become
important during long-lasting flights with short recording intervals for screen layout.

Completion of the flight is detected automatically after landing, or it can be
cancelled by use of the ESC key.
Do not forget switch-off after calculation of the signature.
1.4.4 Data analysis after the flight
Switch-on the instrument and connect to the PC with the Mini USB cable.
Caution: at first the USB driver needs to be installed. This is effected
automatically when installing Flychart, otherwise you need to install the driver
which is compatible to your system software from the CD.
Select the correct interface on the flight analysis program (possible programs
see chapter data transfer) or have it done by search and then download the
flight from the instrument. Several programs provide direct entry to the OLC
or similar online competitions. Flychart
Download the flights regularly from the instrument to the PC and format the
flight memory with Del. All Records in Menu „Manage Memory“. This way
you are ensured to record successfully your flights at any time.

2 Display Screens
2.1 Altimeter and air pressure
A barometric altimeter calculates altitude from the present air pressure of the atmosphere.
Air pressure will decrease at increasing height. Due to the fact that air may be compressed,
the pressure decrease is not linear, but indeed exponential. The basis for altitude calculation
in aviation is an international formula which defines a standard atmosphere.
In the CINA- Standard atmosphere the basic pressure on sea level is 1013,25 hPa
(Hektopascal) at a temperature of 15°C. Furthermore it defines a continuous temperature
decrease at increasing height of 0,65°C per 100m ascent. Therefore is binding: a barometric
aviation altimeter displays the precise altitude only if weather conditions are in exact
accordance to the standard atmosphere. In practice, such analogy is more likely to be the
exception!
Air weight and pressure are strongly influenced by air temperature. If temperature deviates
from standard atmosphere, the display of altitude calculated as per the international formula
is no longer correct. The altimeter displays during summer, when temperatures are higher,
indeed altitude parameters which are too low, and during the winter it is exactly the contrary!
Flying at lower temperatures is effectively done at lower altitude, and at higher temperatures
flight altitude is higher than the altimeter displays! The deviation of 1 °C per 1000 height
meters induces approx. 4 m error. (This empirical formula is valid for up to 4000m!)
If you fly during summer through 2000 height meters in an air mass being too warm by 16 °C
compared to standard atmosphere, the altimeter will then display 2 x 4 x 16 = 128m
difference in altitude under real height! Based upon the internationally determined altitude
calculation with standard values, this display error caused by air temperature shall not be
rectified by the instrument.
Air pressure changes in relation to weather conditions. In order to compensate for display
fluctuations, an altimeter always needs to be gauged. This means that the altimeter has to
be set precisely before take-off for any flight to a well-known altitude value. Caution:
the atmospheric pressure may change during the timeline of one day up to five Hektopascal
(for ex. cold front). As a result this is after all the equivalent of more than 40 meters height
difference.
There is another possibility to gauge the altimeter which is to enter the current QNH pressure
value. The QNH (Question Normal Height) applied in aviation matches the current local
air pressure, as it would be at sea level, so that the altimeter would indeed display 0m.
Due to this process the local pressure data recorded by the various measurement stations
is area-wide comparable, irrespective of the geographical height.
The QNH-value is subject to be continuously updated and may be read in the flight weather
report, or required by radio from airfields, or by enquiry on the Internet.
The instrument provides 3 altitude displays.
2.1.1 Altimeter A1, absolute Altitude A1 is always the altitude above sea level (large display in upper part of display screen).
Altitude A1 is originally set by the manufacturer to show the correct altitude of user’s
location if air pressure at sea level is 1013 hPa. Bearing in mind that this only happens
infrequently, the displayed altitude A1 should be gauged before each take-off to the actual,
true height at location.
Correction of altitude A1:
Long pressure on
F1
⇒ will generate the message Mod Alt1 ↑↓ in the lower information line.
- 12 -
Operating Manual Flytec 6020
Pressing the ▲key will increase the displayed altitude, the ▼ key will decrease altitude.
Due to this adjustment the air pressure display will also change. This air pressure value
(QNH) is always related to the height at sea level.
If the user does not know the altitude of his present location, he may obtain the data
by fading in the „User Field QNH“ and, using the arrow keys, by changing the altitude
value until the QNH matches the actual QNH as per weather forecast.
If the GPS system receives satellites, the GPS-altitude is applied as Alt1 by pressing the
F2
(Alti GPS) key. If there is no GPS reception, it is possible to set the altitude Alt1
by use of the function key
of 1013 hPa.
If the altitude A1 of any given landing place is set to 0m, then after take-off there will
of course always be displayed the altitude above this location. The related air pressure
(QFE) is the real present air pressure at this place in hPa, which differs of course from
QNH, which is the pressure at sea level, according to the difference of altitude.
Within the user selectable fields it is also possible to choose altitude A1 in ft. This
information is important when being in contact with the air traffic manager in
Restricted Areas.
Furthermore it is possible to choose FL (ft) in the user selectable fields. This value is an
altitude display in feet for the Flight level (FL). This feature is not adjustable and is always
related to a QNH value of 1013 hPa (air pressure at sea level). This display is particularly
important for pilots of microlight aircraft to whom is assigned a Flight Level by air trafficcontrollers during flights in Restricted Areas.
2.1.2 Altimeter A2, relative altitude A2 (within the user selectable fields) is a reference altitude, it can be modified by use of the
arrow keys ▲▼.
Correction of altitude A2:
Long pressure on
F2
By use of the arrow ▲▼ keys it is possible to set the height difference, or to set with brief
pressure on
F2

2.1.3 Altimeter A3, cumulated altitude A3 (within the user selectable fields) sums up the total height meters gained during one
flight. For thermal flights this height is dependant on flight time. If several pilots complete
the same flight task, then the one who had the least gain in height (A3) would have been
the best to accomplish the task.

2.2 Variometer functions
2.2.1 Analog Vario
The most important indication for a non-motor driven
aircraft is without any doubt the Variometer.
It displays the vertical speed in meter/second and informs
the pilot about the actual climb or sink rate.
It is only possible for the pilot by using the Vario (and its
accompanying acoustics) to determine the most efficient
thermal climb, and in the opposite situation, to recognise
when he is sinking too rapidly in downwind and should
leave them at best speed.
The scale of the analogue display is 0,2 m/s. The range of
the first scale extends from 0 up to +/- 4 m/s, thereafter the
scale display switches automatically and the range of the
second scale extends from 4… 8 m/s.
.
The response characteristics of the analogue Vario and of climb

acoustics can be set within a wide range. In order to simplify
the settings, Flytec has determined 5 basic filters which can be
set by the Flychart program to particular requirements when
using a special command.

2.2.2 Digital-Vario Average- or Netto-Vario The Digital Vario has a scale of 10 cm/s and an extensive measuring range of
up to +/- 100 m/s. It is therefore also appropriate to display the vertical speed for parachutists
during the jump.
It may be provided with a time constant from 1 … 30 s in the Set-Mode under "Variomode"
as average value-Vario (also called integrating Vario). This feature is useful to provide a
more settled Vario display inside a rough thermal. Integration time should be selected more

damp
Dampening The Variometer value is recalculated every 0.2s. In case of
rapid Vario changes and setting of quickly increasing tone pitch,
this may possibly result between two calculation phases in a
quite important modification of tone frequency. The ear perceives
this incidence as a kind of fast “piano effect”. In order to diminish this
effect, a damping feature may be fitted. Then rapid tone pitches are
honed in the frequency. As a result, the Vario sound has a smoother
response.

2.3 Speed
The 6020-GPS provides a speed measuring inlet for a wind wheel sensor. This item displays
the true flight speed through the air and starts correct measuring above 1 km/h, it is
therefore also very convenient for determination of the wind strength at take-off. The
speed measuring inlet can be adjusted by implementing a correction factor.
Factory setting is always 100%.
Main Setup Menu
This correction is helpful, if the speed sensor can not be fitted at optimum.
The wind vane sensor measures the True Air Speed (=TAS).
Speed is displayed in digital mode.
2.3.1 Speed without Speed Sensor
Frequently hangglider pilots fly without any speed sensor. In this case it is possible
to present the GND-Speed as digital display within a freely selectable user field.
The 6020-GPS calculates from GND-Speed, as well as wind direction and strength
a computed air speed. However, this indication of air speed without speed sensor is
just an approximation to the effective air speed. This is in many cases sufficient to do
certain assessments, e.g. if the goal can be reached or not. The data of wind direction
and strength are established in this case by flying one or more circles. The instrument
computes wind direction and strength from the disparity. It is recommended to pilot’s
flying without speed sensor to fly from time to time an entire full circle in order to
establish wind direction and strength. Due to the fact that the calculated air speed is
related to the wind data present at the location where circling was effected, the calculated
air speed is no longer valid under different conditions of wind data.
The air speed calculated without speed sensor is the True Air Speed.
See Chapter 2.7.3 Wind direction and strength page 31.

Stallalarm is only enabled when wind vane wheel is inserted. Furthermore, it is only enabled
between 15 km/h True Air Speed and the selected Stall speed.
