Just a thought.
JSHG made the following post:
I've had one very severe turbulence incident on an Airbus A300. In the twelve seconds during which we were out of control, the ECAM was producing a stream of messages for electrical and hydraulic failures, all induced by rapidly-fluctuating G forces. If we'd had datalink I assume these would have been transmitted too.
What if the electronic systems responded erroneously to severe turbulence (source of ACARS messages) as JSHG experienced years earlier, and as a result backed themselves out of the control loop, to the point where the pilots could no longer control the aircraft? In other words, a cascade response of turbulence induced g-force "failures" that weren't really failures, but resulted in reduced flight surface control, in the middle of a severe turbulence encounter?
