FLARM
FLARM is a collision avoidance technology popular in the glider pilot community (particularly in
Europe). Sentry Plus is equipped with a FLARM receiver providing additional traffic awareness
for general aviation and light aircraft.
FLARM operates on different frequencies in different regions of the world. The FLARM receiver
in Sentry Plus operates on the European FLARM SRD860 frequency band (868.2 MHz to
868.4 MHz).
To enable FLARM traffic in ForeFlight Mobile, you must purchase a FLARM decoding license.
A FLARM decoding license is associated with your ForeFlight account and can be purchased
at www.foreflight.com/buy.
FLARM traffic targets can be viewed on the map with the Traffic layer enabled while
connected to Sentry Plus.
