including former director of the faa s accident investigation division says this is not about strength. it s about the system itself and here s why. if a plane is in a steep dive, the stabilizer is pushed down. to counter act that, the pilots pull up on the yolk which brings up the elevator, which is the small wing on the tail. if tell investigator is up and the stabilizer is down, they re working against each other. with the jet moving at several hundred miles an hour because of the force, it s difficult for anyone to move the trim wheel. same pilot sully sullenberger backs that up. they need to develop a muscle memory of their experiences so that it will be immediately accessible to them in future, even years from now when they face such a crisis. we should note in the ethiopian airlines crash, the second of the two 737 max
so-and-so, squawk 5512. if they wanted to signal something such as an emergency in flight they would squawk 7700. that can be done in a matter of seconds, so what we can deduce from this is something must have happened and it must have been so severe that it didn t give these pilots an opportunity to number one communicate on the radio system and it didn t give them an opportunity to put in a squawk code. these are the power settings right here. left engine right engine. this is the trim wheel. you can do that electronically or manually. this is the flight management system. it is so easy to touch as a pilot pilot. you can program the entire flight of this aircraft in this flight management system.
