Hi Tecman... you quote..
'with the x/w at maximum demonstrated or beyond, a crabbed approach works best. The crab angle is essentially instantly adjustable'
Whilst you probably do this instinctively, I would still like to ask...How do you instantly adjust the crab angle.. With aileron? or with rudder? Or perhaps you haven't really thought about it too deeply, and just got on with it.
I am still sitting on the fence here, and will continue to fly finals with a partial rudder input. It doesn't look as alarming as a full crab or a full side-slip. (and in a C172 you should not side-slip with flaps down.)
