Good grief! What some people come up with to berate/confuse students….
I can only think of one way this topic should be discussed (for the benefit of all that is rather than to ‘prove’ some point) So here goes
In a turn the outer wing is going a bit faster than the inner one.
The only two terms in the lift equation that can be different between the two wings are lift coefficient (ie AOA) and speed. We have agreed the speed of the outer one is up so it must have less AOA.
In point of fact the only thing that can vary the AOA between the two wings (when the bank is not changing) is the ailerons.
So yes the tip of the outer wing will have its aileron up a bit more than its opposite number.
Unless he was joking feel free to give him a kick from me. A proper kick that is.
