Default "rudder turns"

I have a question for HarryC.

I agree with you about rudder not turning planes. I took an emergency maneuvers training course and that was a basic concept taught.

My question is in reference to adverse yaw and differential lift on the wings. If I pump in left rudder, the plane yaws left. The right wing should move forward into the slipstream while the left wing moves back. The difference in the airspeeds over the respective wings should cause the right wing more lift than the left thus rolling the plane into a left bank. In theory the horizontal component of lift should then "turn" the plane. How can this be explained and tied into your previous statements that rudder "can not" turn a plane?

Granted that such a turn is uncoordinated and dangerous. However it ailerons should fail in a roll position, rudder can be used to compensate for the turn induced and the plane can be safely landed. I learned that in my EMT training. Also the use of the slip involves a yawing of the plane and an opposite rolling to counteract so that the plane flies in a straight line but is yawed.

Would you clarify that for me please?

Thanks
