8.6.1 Thermal display
The Thermal-display (Ill. 2)
The cloud-map of the thermal and the active waypoint is always shown in track up.
The lower half of the screen shows the flying arena as a
square of either 1x1km or 2x2km. Key2 toggles between
these resolutions. If an A is visible in the right side middle
display the instrument automatically changes from
BaroCompass to Thermal mode whenever in lift, and back
again in sink.
An A here means that the instrument will automatically
change from BaroCompass to Thermal mode when
climbing, and back again when gliding.
Pilot position always in the centre of the screen (small
circle)
Thermal visualisation
The thermal is shown wind-drift compensated (see 8.6.2)
Distance to selected waypoint, Mark or back to launch.
Flight duration in hours and minutes
Flashing bearing to next waypoint – in this case almost
due west.
TAS/True Airspeed > Only with speed sensor connected
NOTE!
Display only visible after app. 10s of speed probe activity.
8.6.2 Thermal display Centring aid
Wind-drift compensated visualisation of the lift area. In this display the instrument draws a
track as soon as climb rates of more than 0m/s are encountered. Higher climb rates result
in larger pixel points. If the pilot falls out of the thermal it is easy to fly back into it by
looking at the display. This is particularly helpful on days with considerable wind drift, or for
centring weak Föehn waves. The resulting map of the thermal is wind drift compensated in
an intuitively correct manner, and lift is only drawn up to 150m above or below the pilot
altitude from the last 5 minutes.
