P factor was taught when I was learning and the same laws apply now. Trim once in an ocean of air doesn't compensate for wind, only for misrigging or assymetrical thrust. A jet engine, if it has any AOA, would have slightly more intake on the downward spinning fan but I have never noticed enough to care. I think a lot of folks here are pulling our leg to see if we will bite. Then we have a few that....never mind.
