Kermit. You are right re the POH figures stating normal landing approaches can be made at 55-65 knots flaps down. But 10 knots is quite a wide spread of speeds. As 65 knots will give a real long float, it would seem better to use the lower end of the normal landing speeds ie 54 knots as "normal". That way, the student is in a good position to be able to land on wet grass strips without running off the end into the bushes after a 65 knot float. Also one could argue that if the student is bound for the airline stream he will have to get used to approaching at the 1.3Vs and not adding 10 knots on for prosperity!
