To RA or not to RA
Hello all (CJ Driver inn particular!)
A question please. Most aircraft manufacturers have as a standard procedure that the TCAS should be changed to "TA only" when you have an engine failure (even 4-engined aircraft).
I have a problem with that for a number of reasons. The type I fly is an A340, and this aircraft does not have a performance problem that would limit the climb in the event of a "climb" RA (50% chance of a descent command anyway!).
In addition, the flight control laws prevent the aircraft from stalling.
Airbus insists that the "other aircraft" will manoeuvre based on your TA signal, ans the S band signal tells the other aircraft you are on TA only. My argument is that in Africa, perhaps 10% of the aircraf have TCAS, thus limiting this argument.
Am I missing something in being uncomfortable setting up TA ONLY in a tricky environment?
Thanks
