There are can be altitude limitations on APU use, but on some -200 variants at least, APU use is possible under 20,000', and bleed air is available under 15,000'. There will be a big placard reading "APU CERTIFIED FOR IN-FLIGHT START AND OPERATION" if this is feasible. -- Robert Dorsett Moderator, sci.aeronautics.simulation email@example.com firstname.lastname@example.org "Bother," said Pooh when his engine quit on take-off.
