[NSRCA-discussion] Turbulence

[Nat Penton]

 I think P factor is when the prop shaft is pointed in one direction and the incoming freestream is different causing the prop blades to be at different angles of attack - creating a yaw force.

An example of an extreme P situation would be powering up on an aborted carrier landing for a go around.

I have argued that P factor does not exist due to induced flow. I have been told my view is incorrect.

With the typical taildragger P factor should cause the airplane to turn left before the tail comes up - I think.

       Is there P factor with no crosswind? What exactly is P factor?
