re: APUs that don't work at altitude. I am curious as what is done differently on an APU used on ETOPS planes (which can operate anytime anywhere) and APUs that won't work at altitude. Is it a question of the cold temperature or the lower pressure at altitude ? In either case, what is done on an ETOPs rated APU to counter this problem/difficulty ?
