This FLARM display is oriented track-up and a small glider icon
clearly shows that the display is oriented as such. The scale of
the display is nonlinear (expanded close to the aircraft). On the
background there are three rings; the first is 500 meters, the second
is 1000 meters and the third is 2000 meters. Traffic further away
than 2000 meters is drawn at the 2000 meter ring.
The FLARM gauge display shows FLARM traffic in colours ac-
cording to the threat level. Previously all traffic was shown in red.
The traffic is coloured:
• Green for level 0
• Yellow for level 1
• Red for level 2 and 3
FLARM objects in the radar-like display are shaped in order to
provide information on relative height. Square shapes indicate
similar altitude; a triangle pointing up indicate the traffic is very
high; a triangle pointing down indicates the traffic is very low.
Similarly, intermediate trapezoids indicate relative height in a sim-
ilar way proportionally: thinner at the top indicates the traffic is
higher, thinner at the base indicates the traffic is lower.
The FLARM radar-like display, when enabled, can be suppressed
when visible by pressing the enter button (rotary knob on Altair).
If the FLARM radar is suppressed, pressing the enter button again
cancels the suppression and the radar is shown again. When new
traffic appears in the radar, the suppression is cancelled.
