“I do not trust any fly by wire system any longer.”

My understanding is that this plane is NOT fly-by-wire. Well, that is until ‘the wire’ decides to take over control of the plane.

The 737Max aircraft have digital pilot assist systems which are fly by wire in design. The dynamic surfaces are moved by hydraulic actuators controlled via electromechanical servos that modulate hydraulic pressures. They also have cables directly to the yokes and pedals on the flight deck. The pilot or first officer can at any time disable the electronic assistance and or electromechanical servos and use the cables to directly move the dynamic flight surfaces. To do this you must have the muscle strength to manually move the surfaces if you turned off the hydraulics. A DEI hire who is female , 5 foot a buck O five is not going to have the arm strength to move the elevators maybe the rudder via pedals. You need a strong man probably two to manually fly a modern jet via the cables and no hydraulics. Luckily the cables also actuate the servos so a pilot in a 737 or any other Boeing doesn’t have to turn off the hydraulics to eliminate the computer controls just the electronics then they can fly the aircraft with direct pilot inputs to the hydraulic actuators. Airbus has no means of doing that as it’s 100% fly by wire. This is why Boeing’s are known as a pilots aircraft for real pilots not computer jockies with a flight cert.
