What about Flap failure or Flap control failure (so full flaps when you don't want them / no flaps when you want them). Obviously you need a long enough runway depending on the plane...
What about Clean stalls vs full flap stalls (or is that what you mean by stall recovery from a simulated approach?).
What about taking emergency avoiding action (fun to get a passenger to suddenly say "F16 approaching 12 o'clock") - should ensure that turning right 90deg at a v.high bank angle is instinctive (although I suspect it is more fun in the bulldog than a PA28).
Since I'm still doing my PPL I can't talk about currency (as my instructor has me doing most of them regularly and has recently had me going out on my own to practice PFLs, stalls, etc) but to me practising clean and full flap stalls is a non-event also. I'm not sure why some people seem scared of them?
