Yesterday evening, I was watching Die Hard (The airport one) and there are several thought's which cropped up in my mind about some of the things the terrorists did to cripple the airport.
Firstly,
following provocation, the terrorists altered the descent path of the ILS beam, setting it some 200ft lower than the runway, sharpening the path and meaning (so it would seem) that thier onboard systems show them some 200ft higher than they are in reality.
However, my friend pointed out that surely there would be many cross-checks they can do on approach to distinguish as to where they are and make adjustments in according with descent rates and so on????
also in reality, the pilots are required to actually see the runway before proceeding to land the aircraft - in the film the runway appears seconds before they crash..I also remember you have to check the status of the papi lights to the left of the runway...so surely a crash wouldn't be possible - or would it?
