Yes, minimum sink speed is less than best glide speed, but it's still a safe and useful flight speed. Don't always need best glide to make a dead stick emergency landing. The current airplanes have a mark at stall and stall is always a useless speed to fly. The lower safe airspeed mark should rather be somewhere higher than stall, but where exactly is undetermined.Isn’t minimum sink speed significantly slower than best glide speed?
I think he was saying fly at 1.4 X stall speed which for my plane is about 5 knots faster than best glide speed. No idea what minimum sink speed for my plane is (maybe 5 knots below best glide speed)?
I agree it is better to stay above best glide speed and his 1.4 X stall speed seems about right for me. Heck, that probably approximates best glide speed with a 5 knot headwind.
