Unless Boeing’s design philosophy has changed, the pilot is always able to override the computer inputs by simply “hand flying” the airplane using conventional flight controls The auto throttles are not the autopilot. The auto throttles, if engaged, would sense an overspeed condition and reduce thrust, not “cut power.”
All of your power speculation has nothing to do with “fly by Wire.” Whatever happened will be determined after recovery of the Black, (actually orange) box. (actually a cylinder)
The Airbus someone mentioned will not allow the pilot to stall the airplane. Cheers.
You can call, or not, it whatever you want but a computer is telling the control actuators what to do. Erroneous input data, ie, airspeed indicator could cause a reduction in power at a most critical moment.
IR a brand new Airbus on a demo flight, flown by a senior Air France pilot making a low pass over the airport. The plane pancaked into the trees at the end of the runway. The final outcome was pilot couldn't get the plane to climb.
Air France flight 296, an Airbus 320. A demo flight.
Among several causes, the final report...
The crew applied full power and the pilot attempted to climb. However, the elevators did not respond to the pilot's commands, because the A320's computer system engaged its "alpha protection" mode (meant to prevent the aircraft from entering a stall). Less than five seconds later, the turbines began ingesting leaves and branches as the aircraft skimmed the tops of the trees. The combustion chambers clogged and the engines failed. The aircraft fell to the ground.[4]
