Dogle,
I once had to land back at Syerston in the middle of a downpour. An ASK18 on approach with a reasonable headwind barely shifts the drops, so a bit of side slip and visual through the "DV window" was used. Luckily I never encountered icing during my gliding time, had I done so I feel sure the same procedure would have worked. Hope that helps, looking forward to the pro power pilot Danny and why he didn't do a straight air brake controlled approach to land. I would say that there was always something about the "solid feel" of stability and control once the brakes were out, apart from the fact that you were going to land whatever, there was always, on every glider I flew, a feeling of great control with the brakes.
