<DIV><FONT face=Arial size=2> 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.</FONT></DIV>

<DIV><FONT face=Arial size=2>An example of an extreme P situation would be
powering up on an aborted carrier landing for a go around.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have argued that P factor does not exist due to
induced flow. I have been told my view is incorrect.</FONT></DIV>

<DIV><FONT face=Arial size=2>With the typical taildragger P factor should cause
the airplane to turn left before the tail comes up - I think.</FONT></DIV>
