FF,
regarding the leading with rudder. I use this phrase because there is a tendency when told 'use aileron and balance with rudder' they glance at the ball as an after thought even though we say use harmonise the two together. The result often is that the rudder goes in late, during the turn when it is not needed
(i.e. the ailerons are in the neutral position).
So, I suggest to them think Rudder/aileron in that order. It usually results in the two happening together as required.
My philosophy is to prevent the adverse yaw rather than correct it, which despite the protests here, most and I mean most of the qualified pilots I fly with do.
I also think that there is a longer delay between thought to foot and thought to hand actions.
Wing drop on the approach? At an airfield like Elstree or on 18 at Cranfield where there is always a significant amount of turbulence the aeroplane is constant lateral motion. That is what I am referring to, not wing drop due to slow speed.
Incidentally, I was having a check in a Twin the other day when an experienced multi - instructor informed me that you don't need rudder because it is a twin??
I used to fly a Seneca that had a STOL kit, full span flaps and spoilers instead of ailerons, and on that you didn't get aileron yaw, but on a normal twin???
S&L
I fly a lot without the ailerons, the rudder nothing to do with turning the aircraft. It just causes yaw.
AS you stated the further effect of the yaw- roll, causes the lift vector to be offset causing the turn.
