Q for GtE: Why landing flaps? My thought would want to reduce the possibility of sink, even if I am 5-10kts faster. Maybe one stage of flap?
Two reasons, firstly if the engine has stopped and I am going to hit the ground anyhow it makes little difference to me whether that's in 4 minutes or six. Secondly, land flaps will make the descent angle steeper (thus reducing the risk of hitting a mast) and stall speed as low as it'll go, so my energy when I do finally hit something is as low as possible.
OK, for the rest of you, if you don't feel competent enough to do a Vne dive then dive at Vno.
Again, I'm descending anyhow, why risk loss of control by doing it in anything other than a sensible low speed / lowish sink descent. If I come out of cloud at Vs+5 at 100ft, or at Vno at 100ft, my odds of controlling the ground impact in a reasonably horizontal manner are far better at low speed. This is for the very simple reason that a significant amount of height is lost in changing from a fast dive to horizontal flight.
If I know that I'm going to come out at a reasonable height above the surface, I'd use min.sink, but if I don't, I'll stick with Vs+a_little_bit since that's the best thing to hit the ground at.
