IPC design validation and flight testing final report
March 31, 1978
A series of flight tests were conducted to evaluate the collision avoidance system known as Intermittent Positive Control (subsequently re-named Automatic Traffic Advisory and Resolution Service, ATARS). These tests involved both professional test pilots and subject pilots selected from the aviation community. This report includes analysis of the collision avoidance algorithm, pilot visual acquisition performance, and pilot reaction to avoidance instructions.
