Receiver signal modes A. C.and S. This tells me it receives these signals? Why would you need to be in a radar environment if it works like TCAS? Does TCAS not work outside the J curve?
You are the expert in everything, so you tell us. I am drawing Jabawocky's attention to a device that Hawker Pacific, you know that Australian mob, advertises as agents a portable GA collision avoidance for what appears to be a very cheap price. This may allay some of his fears of flying. They advertise a phone number, 1 800 654 983 so you can ring and ask yourself.
