A MID-AIR COLLISION THREAT ALGORITHM THAT USES BEARING DATA

This paper derives an algorithm for use by an airborne mid-air collision avoidance system to determine when an alarm should be given in case a mid-air collision is imminent. The algorithm is based on an extension of the standard modified tau alarm criterion used in most collision avoidance system threat logics. The standard criterion uses only altitude and range data and, as a result, will generate high alarm rates in heavy air traffic. The criterion presented here makes use of bearing data as well as altitude and range data and should, therefore, provide lower alarm rates. (Author)
