What puzzles me is why aeroplanes that will be driven by the computer rather than the pilot ever got certified with a system like this.
Didn't the people who programmed the computers (or specified what the computers should make ther aeroplanes do) think about making them fit in with the other parts of the aviation system?
I presume that no-one would design a computer that requires an aeroplane to sit on a runway for three minutes after being given a take-off clearance (would they?) - so why three minutes before the darned thing will descend????
