I know that TCAS displays are mediocre in azimuth, and that their
accuracy in
this respect depends hugely on the design of the hardware on the local
aircraft (since it must depend essentially on radar sweeps to determine
azimuth). Distance is more reliable. Altitude depends on the accuracy
of the
remote transponder.


TCAS is not the only traffic display device out there.


What other ones are there, and how do they work?

PLEASE REAL PILOTS: IGNORE WITH THIS PRETEND PILOT HAS TO SAY. HE IS A
GENUINE HAZARD TO AVIATION.

I can just see planes falling out of the sky right after reading one of MX's
posts. I'm more concerned about someone who would think such a thing is
possible.
