Dick, when are you going to get it that traffic avoidance is NOT traffic INFORMATION.
The only thing that is accurate on your little TCAS screen is the baro from the target aircraft.( and only then if the target aircrafts owner has a regular check of his system) You are a very brave man to rely on azimuth information solely from a TCAS unit.
I would trust a little PDA screen hooked up to ADS-B with "IN" over a TCAS anyday for TRAFFIC INFORMATION!
