With the spiral staircase analogy, I still can't get my head around how, on a descending turn, the AofA would be higher on the lower wing. I understand climbing turns easily, it's logical that the AofA would be higher on the higher wing, but in my mind it still seems that the AofA should be higher on the upper wing during a descending turn as well...I'm sure there's an obvious explanation but I can't get my head around it, anyone want to try to explain? :)
