Map Screen
ESC is used to select the Map Mode. It is followed by the illustration of the flight track
(North is located at the top!). Additionally stored waypoints are plotted with a cross and name,
and the scale is indicated in the lower left part.
F2: Zoom in: The map scale is gradually increased, up to approx. 0.5–1.0 km. Thus
single circles are clearly recognisable (dependent on the Recording Interval settings)
F1: Zoom out: The map scale is gradually decreased until the display screen is
optimised.
OK: Return from any display back to optimised display screen.
ESC: Return to flight selection Menu
All other keys cause the track in the current selection to be redrawn.
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.

Final approach screen
The final approach screen serves as an assistance for the final glide. It is less suitable for
the normal flight. It will normally be activated in the last thermal before the goal.
The horizontal scale shows the deviation between current track and bearing (direction to
the goal). 1 graduation line is 10°, between 2 large lines there are 20°. The vertical scale
shows the deviation between the required lift/drag ratio to the goal and the ratio of best
glide of the aircraft, such as it is adjusted in the Basic Settings. One graduation line
corresponds to 0,5 lift/drag ratio. There is one lift/drag ratio between 2 large lines.
The example shows an aircraft with lift/drag ratio 8. The required L/D ratio to goal is 5.7.
The aircraft symbol is positioned by 2.3 units above the point of best glide.

1.6 Entering Text
It is possible to enter text for certain fields, as for example pilot’s name, type of aircraft,
aircraft ID, or in regard to Waypoints or Routes the required text on the instrument.
However, this procedure is quite laborious. It is indeed much more easier to implement
the text entry on the PC by use of the program Flychart 4.52 and to transfer subsequently
the data to the instrument.
Text entry on the instrument is demonstrated here for the example of a Waypoint:
by use of the keys ▲and ▼one can select a single Waypoint and alter it after pressing
the OK key.
The 1st letter of the WP name shall be flashing. Now again by use of the ▲and ▼keys
the required letter is selected; numbers, letters as well as a range of special characters are
available.

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.

Operating Manual Flytec 6020
- 13 -
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 F1 (Alti 1013) to a value which complies to QNH pressure
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 traffic-
controllers 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 ⇒will generate the message „Mod A2 ↑↓“ in the lower information line.
By use of the arrow ▲▼ keys it is possible to set the height difference, or to set with brief
pressure on F2 (SET 0) the height difference to 0.
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.
A2, A3, FL or QNH can be selected within the user selectable fields.

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.
Setting of basic filter:

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
longer in accordance to the thermal’s roughness.

2.2.3 Acoustics and Volume Level (Sound)
The Menu Climb acoustics facilitates the versatile setting possibilities of the Flytec 6020 GPS
Vario – Acoustics. This feature enables a rapid and easy adaptation to the pilot’s requirements.
By short pressure on the key the volume level will increase each time by 25%.
The adjustable sound levels are: 0 - 25% - 50% - 75% - 100% - 0. The selected value
is displayed on the information line and confirmed with a short beep or double-beep.

will be slowly increased automatically, once the airspeed exceeds 40 km/h. However, it is
impossible for the volume level to exceed 100%.

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.

The Sink tone is continuous and is heard with deeper sound pitch at increasing sink speed
and is slowly again increasing in frequency when approaching rising air.
Starting point The starting point of sink acoustics can be selected just as in
climb acoustics. The threshold can be set by use of the ST
arrow keys.
During flight the Sink tone can be switched-on or switched-off
by short pressure on the key. Then one can see upon
switch-on the selected starting point in the analogue Vario

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
⇒ User Settings ⇒ Speed ⇒ Settings Wind Wheel.
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.
2.3.2 Stallalarm
This audible alarm is consisting of a deep tone with short beeps and always with 100%
volume level. In Main Setup Menu
⇒ User Settings ⇒ Speed ⇒ Stall speed it is possible to
set the speed for activating the stall alarm, and likewise, the altitude can be set to the point
from where up the alarm is active. If the stall alarm is set to the value of 0 km/h, the alarm is
turned off.
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.
2.4 Time of day and Date
Caution: time of day and the date do not need to be adjusted. They are taken automatically
from the GPS-Receiver. However, any time zone difference from UTC (World Time) needs
to be entered with a positive value if the time zone is located East of Greenwich, or a with a

Operating Manual Flytec 6020

negative value, if it is at the West. Time zones with 0.5h UTC Offset are also adjustable.
These settings are effected in Main Setup Menu
⇒ Instr. Settings. ⇒ Time zone
Notice: all internal calculations of the instrument are made in UTC (Coordinated Universal
Time). The local time is just used as „Time“ display and calculates simply the UTC plus or
minus the UTC Offset.
The local time is also binding for the take-off time at Competition Routes.
2.5 Temperature
The instrument Flytec 6020-GPS needs a temperature sensor for the temperature
compensation of sensors, as well as for the automatic display contrast control.
Temperature reading is possible in degree Centigrade or Fahrenheit.
Main Setup Menu
⇒ Instr. Settings ⇒ Units.
Caution: the sensor measures the circuit board temperature. The inside temperature of the
casing may be higher or lower than the ambient air temperature, especially when the
instrument is exposed to direct sunlight.
2.6 Navigation
Navigation activities without operating GPS-Receivers is unthinkable these days.
Indeed a chain of satellites is orbiting the Globe. It provides the possibility to determine
worldwide one’s own position very precisely, if min. 4 satellites are received simultaneously.
The Flytec 6020-GPS computes various indicators via the positioning feature by GPS.
2.6.1 Assessment of reception quality
The 6020-GPS is fitted with a 16-channel GPS-Receiver which is featured with
lesser power consumption and also a significantly shorter satellite detection time.
Accuracy of position is between 7 to 40m. As an average one may assume approx. 20 m.
Normally the instrument recognises its position under unobstructed view conditons after
maximum 1 to 2 minutes. If the receiver is switched-off for a short time (less than 2 hrs.),
the time for new position finding is less than 10 seconds as a rule. Buildings, mountains or
thick forest affect reception quality of the receiver. Therefore, one should always look for the
best possible visibility around and the antenna in the casing should be pointed upwards if
applicable. In particular when mounted on the steering holder of the hangglider,
we recommend not to have the instrument fixed under the pilot’s head on the middle of
the basis, but indeed sideways. In this position the 6020-GPS should not have more than 45°
deviation from horizontal position so that the antenna points upwards.

Operating Manual Flytec 6020
- 19 -
Because the receiving intensity of the satellite signals is only approx. 1/1000 of mobile
radios, any radio equipment and other disruptive factors (like notebooks) should be operated
as far away as possible from the 6020-GPS.
The number of received satellites is shown on the upper right side of the bar scale.
The longer the bar, the more precise is the reception quality.
As soon as the instrument has sufficient GPS reception after energising, the date and time
of day is recorded into the internal memory. This action is signalled by the instrument with a
slight beep tone.
2.6.2 Compass and Flight Direction
In contrast to a normal magnetic compass which is oriented to the magnetic force lines of
the Globe, the GPS compass can show the direction only when the user moves about.
However, it has the advantage that it is not subject to any grid deviation and does not show
any deviation as a result of iron or any magnetic material either. Its zero point always
corresponds with the true geographic north (=0 or 360 degrees).
The course, that is the flight direction (= Track), is calculated from a series of positions. If the
user remains stationary at the same location, then the course and compass needles are
undefined. The exact course (this 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 only appears to turn; in reality the needle does not move; it’s
the casing along with the aircraft, which moves around the rose.
2.6.3 Track und Bearing
The Track is defined as the direction of movements of the aircraft over ground.
The geographic true North is always 0 or 360 degrees (East = 90, South = 180, West = 270
degrees).
As the bearing is designated the direction (according to the system described above) to a
selected waypoint seen from the viewer.

Operating Manual Flytec 6020
- 20 -
Caution: Track or Tracklog is also called the sequence of recorded positions during one
flight.
2.6.4 Waypoints and coordinates
A waypoint is any single point on the earth’s surface that you would like to go to.
The 6020-GPS can save up to 200 different waypoints. Each waypoint can have up
to 16 characters, e.g. “Fiesch Airfield”. In determining the waypoint, it is also necessary
to enter the altitude, i.e. “1123” meters (always above sea level). We now only need the
positioning of waypoint on the earth’s surface. For this purpose the 6020-GPS utilises the
geographical map system named WGS84 (World Geodetic System 1984).
This reference system assumes that latitude is measured from the equator to the North Pole
with 90° N, and to the South Pole with 90° S. Longitude is measured from the Greenwich
zero meridian (near London), East is counted positive and West is negative, up to +/- 180°.
The 6020-GPS also understands waypoints entered according to the previous norm,
introduced by Bräuniger: 3 letters and 3 numbers. Example: FIE112 indicates a waypoint
with the name FIExxx and an altitude of 1120 meters above sea level.
In Basic Settings / Coordinate Format the data entry format is selectable between:
1) Degrees Minutes Decimal places of Minutes (dd°mm.mmm) (Factory setting)
2) Degrees Minutes Seconds (dd°mm’ss“)
3) Degrees Decimal places of degrees (dd.ddddd)
4) UTM (a grid system with 1 km raster in both NS and also in EW direction)
5) Swiss Grid
Basically one should always select the first possibility (=factory setting), because only this
format is using exactly the same calculation format as the GPS receivers do. With all the
other formats rounding errors could sum up to 20 m.
Computing is only done with the WGS84 system. Differing geodetic systems can no longer
be selected.
