Tourist - how would your totally computerised aircraft have handled the AF447 scenario?
Ah, perhaps a bad example!!
If the autonomous programming was not allowed to hand back control to a flight crew, then it would have been programmed to do another level of fallback. Which would almost certainly be something like "power and pitch".
It would have had to decide which 2 of the following to ignore: Overspeed, Stall, and Unreliable Airspeed.
You appear to have suggested that it should ignore the Overspeed & Stall warnings by going to pitch and power (assuming it is programmed). If the aircraft was actually stalled, as in AF447, applying power immediately would probably exacerbate the problem and indeed airbus recommend lowering the nose first, if you are stalled. The aircraft has no way of knowing which was which was correct, even if it referenced the GPS it would still have to decide based on majority (e.g. 3 GPS say we are slow, 3 ADIRUs say we are overspeeding and slow at the same time). What does the logic do now?
