For the fun of technical discussions;

Thanks for the information about a failed engine on a twin-prop craft.

No one, including Mr. X, appears to dispute that the descending blade creates a greater aerodynamic force. The discussion appears to be more about the order of importance of the various couplings.

What is difficult to understand is Mr. X's myth.
MYTH: AT POSITIVE ANGLE OF ATTACK, THE DESCENDING PROP BLADE IS AT A HIGHER ANGLE OF ATTACK, SO IT PUTS OUT MORE LIFT, PULLING THE PLANE LEFT.
Is he talking about LIFT, and if so, is he referring to a PULLING THE PLANE LEFT by the increased roll inducing counter-torque of the rotating propeller; which will be compensated for by the ailerons.

~or~

Is he talking about THRUST, and if so, is he referring to a PULLING THE PLANE LEFT by yaw; which will be compensated for by the rudder.
