A method and a system for avoiding collisions between aircraft. The method includes computing a default fly out maneuver regarding how the aircraft shall be maneuvered during a fly out action, predicting a fly away path including a prediction of the position of the aircraft during the fly out maneuver, sending information about the own fly away path to the other aircrafts, receiving information about fly away paths from the other aircrafts, detecting an approaching collision, and activating the fly out maneuver upon detecting an approaching collision. The method further includes carrying out the following steps after activation the fly out maneuver: receiving the current position of the aircraft, and calculating a compensated fly out maneuver for the aircraft based on the current position of the aircraft, the previously predicted position, and the default fly out maneuver.

System and a method for automatic air collision avoidance

A system and a method for automatically avoiding collisions between own aircraft and other aircraft. The system includes a computing unit configured to compute a fly away path for own aircraft, a sender configured to send the computed own fly away path to the other aircraft, a receiver configured to receive fly away paths from the other aircraft, and a collision handler configured to detect an approaching collision based on the own fly away path and the fly away paths received from the other aircraft, and activating a fly away maneuver upon detecting an approaching collision. The collision handler is adapted to receive information about commanded maneuvers of own aircraft, and to detect an approaching collision based on own aircraft maneuvers commanded during a time period between sending the computed own fly away path to the other aircraft and detecting the approaching collision.
