Can any Airbus guys say how often they have to fly in Alternate Law? Is it a regular occurence or something you just experience in training?
6K+hrs A340/320 - never.
Very rare on the line, of course practiced in the Sim.
if cruising at max altitude and you receive a tcas alert to "climb", don't do anything; the other aircraft will get tcas alerts to descend at a higher rate
I trust your advice not to climb is not serious
How do you know the other aircraft even has TCAS? If you are Max Alt, and TCAS says climb, then FOLLOW IT
