I still believe the statement "the outer wing has a higher angle of bank in a climbing turn" is incorrect.
Assuming some dihedral, the outer wing would have a greater angle of bankthan the aircraft, and ineer wing, when the aircraft is banked.
More forward speed gives a lower 'relative airflow' which equals higher AOA.
I do not agree. In the turn, the angle of incidence of both wings is the same. while the relative airflow over each wing is not. The outer wing has a faster relative airflow, as it is flying a larger radius than the inner wing, in otherwise still air. The wing with the slower reletive airflow has the greater AoA. In the most extreme, were the turn to be so tight that its pivot point was the inner wings wing tip, that wing tip would have zero relative airflow, and therefore an apparently infinate AoA.
If the foregoing were changed to read:
Less forward speed gives a lower 'relative airflow' which equals higher AOA. I would agree with it.
