CPB,
Yes, my explanation may have been a bit "Clunky". My point was an aircraft in a turn IS being accelerated, and this produces a force which is indistinguishable from weight. The wings must therefore produce additional lift to balance that force, and can only do so by increasing either speed or AofA.
It was mearly intended to show how barking the concept of "Reduced apparent wingspan" as laid out by ATPTQ is.
