Cheers for the thoughts on this.
Pilotdown man, I understand what you're saying but the design ceiling is not just for pressurisation. Believe me, in a heavy 737 at 37,000' there can sometimes be very little manouvre margin to play with. I do agree, however, that if TCAS said climb...I would climb!! No question.
Capt Pit Bull, the cause of that spurious RA was an aircraft that had come back from maintenence with what we believe was an incorrectly wired TCAS system. It had various spurious 'events' over the course of a week. Not particularly pleasant when it doesn't resolve after a 5000'+ climb
Thanks once again,
