Filter type Depending on the condition, if the air is quiet or turbulent,
one can select 5 different filters. See „Analog Vario“ page 14.
The warning sound for Stall alarm is a pitch tone of medium height with a very fast interval
rate and always at full volume level of 100%.
All sound effects described here above may be heard in simulation mode.
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%.

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air speed is no longer valid under different conditions of wind data.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

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
