A portable collision avoidance system is a proprietary aircraft collision avoidance system similar in function to traffic collision avoidance system. TCAS is the industry standard for commercial colli
Example of a PCAS device
Step 1: Transponder interrogation by ground RADAR or active systems (TCAS)
Step 2: Interrogation reply from transponder-equipped aircraft
Step 3: PCAS computation of aircraft 3-axis information
An airborne collision avoidance system operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collisi
