was asking for to climb to 38,000 feet. that is the very top of this aircraft s flight envelope. the airplane may have been arguing with the pilot not wanting it to climb that high. i ve seen accidents in the case of fly by wire technology pilot is fighting the airplane because the airplane doesn t do what the pilot wants to do. they get confused and causing a bad emergency. great example of that air france crash. they were in a thunderstorm, about 32 35,000 feet. what happened the plane in thunderstorms, for some reason the pito tube airspeed indicator got clogged up with ice. that started cascade of events. they had three pilots on board and could not figure out why the plane kept going down and kept pulling up nose instead of getting airspeed and pulled up the nose and stalled and hit the ocean. when you hear about no pan pan no may stay from 38051.
