I dont buy Chris's point about angle of attack changing as a wing drops =
on the ground, if the tail is on the ground there is no pitch change, =
atlthough it would be true banking into a turn at flying speed. =
Personaly I think the propwash and/or crosswind effect is much more =
important, given that the prop wash on most tugs affects the right =
wing, if that is tending to drop, it will lift in the propwash ( we use =
that affect in a downwing takeoff). Conversely a crosswind from the =
right and the propwash causing the left wing to drop can quickly get out =
of hand.=20
