Hey everyone.
First forray into this forum but i've been pondering this one over the last week or two as I suddenly realised I had a gap in my knowledge about it. I can't find a definate answer to it in my tech manuals either so any input would be appreciated.
Does TCAS take into account aircraft performance/limitations when issuing RA's?
For example, i'm sat at 20,000ft flying level and someone is climbing up underneath me. The resolution in this instance (I assume) would be for our aircraft to climb and the aircraft underneath to either reduce rate of climb or descend. Now take this scenario upto 37,000ft which happens to be my type's ceiling. Would TCAS still issue the climb command?
Of course I appreciate that at that altitude (unless it was military traffic or something similar) the rate of climb of the lower aircraft would likely be low enough to allow the TA time to wake up both crews. My question is more hypothetical I guess but I must admit i've no idea what the answer is!!
I've had a spurious RA in the past which commanded a very high rate of climb over a long period (roughly FL100 upto FL190 ish) and it didn't appear to be taking into account that the speed was slowly bleeding off with the engines at full climb power. Again, I don't know if this was down to the 'faulty' nature of the RA.
Cheers,
