Abstract: A collision avoidance arrangement where aircraft transmits and receives radio signals modulated by a digital pulse sequence (34), if a potential collision is detected (35) the arrangement is adapted to transmit and receive interrogation radio signals and from these signals each aircraft estimates the closing speed of the aircraft (36) and then determines the range between the aircraft (37), and the arrangement also being adapted such that each aircraft transmits to the other the estimate of the closing speed calculated aboard the aircraft and then averages the estimates of the closing speed from each aircraft to obtain a more accurate value for the closing speed of the aircraft.

Abstract: An aircraft collision potential warning system in which each aircraft includes means for transmitting pulse sequences, in pseudo random or random fashion and on a common frequency, which include aircraft identification and altitude information. Each aircraft further includes means to receive and process incoming signals from other aircraft and, on the basis of the altitude information, discard those signals not within a collision potential altitude range. If a signal is within a collision potential altitude range, interrogation is effected specifically to the identified signal source and the closing speed between the two aircraft is determined. If the rate of change of closing speed is below a set figure, a collision potential exists.
