A PROBABILITY ASSESSMENT OF THE FLIGHT SAFETY RELEVANT TO COLLISION AVOIDANCE

摘要

key aspect of Air Traffic Management in the future is to determine (i) the technical requirements to (ii) ensure safety with (iii) increased capacity. The methods to calculate collision probabilities have been applied to reduced vertical separation minima, to lateral separation, to crossing aircraft to free flight and to flight in terminal areas. In the present paper the cumulative probability of coincidence (CPC) is calculated for comparison with the ICAO Alternative Target Level of Safety (ATLS) probability of collision per nautical mile. The comparison of the CPC with the ATLS is made for four typical cruise flight conditions.
