7 AIRSPACE, TRAFFIC AND TEAM FLYING
Browse opens Airspace Browser .
7.9 FLARM traffic display
If connected to a FLARM device, FLARM traffic is displayed on the map area. Each FLARM aircraft
received is drawn as a dashed red disk.
Do not use XCSoar for collision avoidance, as FLARM audio devices are much more
suitable in assisting the pilot to be aware of traffic.
Note that unless one is circling, the usual zoom level is such that FLARM traffic will not be easily
distinguished. When one is circling, or if the user has North-Up screen orientation, this makes the
map display a poor aid at helping to locate the traffic.
FLARM map display
The FLARM targets on the map are drawn as red discs and also have black/blue arrow heads
to indicate the direction the FLARM target is heading. Note that these arrow heads are oriented
according to the display orientation. For example, if the orientation is track-up, then the arrows
show the relative track bearing of the target to the aircraft. If the orientation is north-up, then the
arrows show the absolute track bearing of the target.
Display on the map FLARM of aircraft registration or pilot name is made possible via a look-up of
the ICAO aircraft ID of FLARM traffic in a file. See 12.16 for details on this file format. Aircraft with
the FLARM privacy flag set will not have any identification displayed.
FLARM radar
To remedy this situation, when FLARM traffic is received, the lower right corner of the screen shows
a small radar-style view of the FLARM traffic from the perspective of the aircraft. The FLARM radar
can be opened with F9 even when there is no traffic. FLARM traffic is displayed as coloured
squares on the radar.
This FLARM radar 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.
