This question already has an answer here:
During my PPL training, We practiced some emergency procedure on Piper cherokee and simulated flight controls failure.
My instructor asked me to sit on one hand and place the other on the trimmer.
I had to fly the aircraft using only rudder and trimmer, using trimmer and power for pitching and rudder for direction until short final.
My question is... Can the same procedure be exercised on big aircraft like Boeing?
