The 172M I fly has a flap switch that you need to hold up to raise flap but you don't need to hold it down to lower it (i.e. you just flick it to the down position and it will lower all the flap if you leave it alone). I was wondering if this is unique to that 172?
I unwittingly flicked it slightly on downwind during my checks once and wondered why we had started to balloon before I realized it had lowered 20 degrees of flap and was going for the last 10 before I stopped it.
