Threat Classifications – Zone Division
Basically, the collision warning is based on the comparison of the own
position with the location of surrounding traffic. With ADS-B traffic, this is
done using the respective position reports. For Mode S traffic (not ADS-B
capable), the field strength is measured. The proximity of FLARM
®
traffic
is detected whenever a signal is received (which suffices as the
maximum range of FLARM
®
reception is relatively small).
The priority of a collision warning is determined on the basis of three
predefined zones. These are defined in each case by a distance radius
as well as by an altitude range around own position.
