Transponderz

In equipment I fly (MD11 with TCAS II) I get azimuth and distance (estimated) with no altitude info. If I'm in Class A airspace, I don't worry about it a lot. Down low, I start looking.

Even though the TCAS function doesn't work, is the approaching jet made

aware there are transponders at that 2-D position, altitude unknown?



What happens when the jet approaches a Mode A equipped aircraft? Is the

pilot made aware of it, even though the TCAS system cannot give him

climb/dive command?
