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.
