I would not expect there to be a key, per se, but do the onboard computers use a password, or something similar, to prevent this from happening? Do aircraft manufactured by different companies use different methods? Does access vary by airline, i.e. to prevent, say, a United pilot from flying away with an American Airlines plane? ==== No airliners that I know of have anything like a key or password implemented to prevent "unauthorized" startup. On the other hand, to the untrained person, there is no obvious way to start the engines - usually the procedure has multiple steps, if it's not downright complicated. Your scenario of a UA pilot starting up an AA aircraft is possible - so long as the engine start procedures are the same (i.e. if the engines used by both companies were essentially the same.) Note that, even with the engines started, the aircraft probably couldn't go anywhere - you generally need a ground crew to remove chocks, etc. And aircraft other than the DC9/MD80/B727 would generally need someone on a tug to back them out of a gate area. ed -------- Ed Hahn | email@example.com | (703) 883-5988 -------- The above comment reflects the opinions of the author, and does not constitute endorsement or implied warranty by the MITRE Corporation.
