If you sit in the command seat of a B737 and watch
- a thrust lever split
- the autopilot rolling on aileron
-the trim wheel in motion
-asymmetric engine indications
-asymmetric rudder pedals
and you cant figure something is happening then you shouldn’t be there.
Just for a moment consider the millions and millions of flight hours flown safely over the life of this airframe.
Its not the aircraft.
