What I am curious now, is what was the input of the pilots and did the aircraft obey them, or did the duped protections still inhibit a eventual stick down input!
Flying at night, at cruise altitiude, over the ocean, no visual refs... In the middle of some nasty weather... Airspeed indicating overspeed. Who would pitch down an aircraft under these circumstances?
By the way... GPSes does not get clogged by ice. How much tail/head-wind would be required to stall/overspeed an aircraft if GPS speed was used as input to AP/AT? Of course, it would not be the one and only speed reference. Say, we use GPS speed as a "sanity check" to catch a clogging pitot? Is it even possible? Probably not...
