| 1. A method for avoiding collisions between own aircraft and one or more other aircraft, wherein each aircraft comprises an
automatic collision avoidance system, the method comprising:
computing a fly away path for own aircraft,
sending the computed own fly away path to the other aircraft,
receiving fly away paths from the other aircraft,
detecting an approaching collision based on the own fly away path and the fly away paths received from the other aircraft,
and
activating a fly out maneuver upon detecting an approaching collision,
wherein detection of an approaching collision is based on commanded maneuvers of own aircraft commanded during a time period
between sending the computed own fly away path to the other aircraft and detecting the approaching collision, wherein the
method comprises receiving the commanded maneuvers and detecting an approaching collision based on the commanded maneuvers
received during said time period.
