@BOAC - Thanks, that was what I was looking for
@Mark1 - I wonder - theoretically I can load a 172 to considerably more clean than I can with flaps....
@Intruder - you are correct, I'd not considered the sustainability factor of corner speed. Anyway, forget calling it corner speed - It's min radius I'm interested in!
As for min speed, max bank - no:
At Vs, I cannot roll out of wings level/1g or I'll stall - I'm confined to a straight line, so it's not that.
At Vne/Vno (and anywhere above Va) I'll be limited by airframe load factors, and could pull just as hard at lower speed, which, with less Kinetic would turn tighter. Between those boundary conditions, there's going to be an optimum trade off of speed vs increased lift available from the wing.
In any case, fear not, I'm quite au-fait with basic aerodynamics, and I'm not about to plod into the mountains based on pprune advice, or even just reading books. Simply an idle tuesday afternoon wondering - I have V speeds for about everything else and set me thinking.
