Before someone comes on a states what I have said doesn't always work.
It does in a SEP VFR aircraft that's not damaged or carrying ICE.
If you have taken a bird strike on the leading edge, at altitude set the aircraft up in the approach config and gradually reduce the speed back to normal, Carry out a couple of turns. If everything feels ok land as normal.
If you start feeling anything note the attitude/speed and reduce slightly and that's your new approach attitude/speed.
Icing is a bit different as you don't want to hang around picking more of the stuff up. Your stall protection won't work either. So you just have to be conservative. and slow and any hint of buffeting go faster by 5-10knts.
