Abstract:

The study analyzes the Collision Avoidance System CAS development by McDonnell Douglas. The McDonnell Douglas CAS uses the time frequency technique which was adopted in the ATA ARINC characteristic No. 587-2 92171. The primary purpose of the study was to ascertain the capability of the CAS to operate in a dense air traffic environment such as that expected in the Los Angeles basin LAX in 1982. Of particular concern in the analysis were problems associated with airborne equipment synchronization and multiple slot occupancy and their effect on reducing system capacity. In addition an analysis of the tau alarm accuracy was performed. The McDonnell Douglas CAS is a time frequency multiplex system in which each CAS-equipped aircraft attempts to select a mutually exclusive time slot in which to operate.
