Capt. H. The 54 knots at the flare off a glide approach is quite safe in my experience based on the POH assertation at page 4-21 that you can land power off or on at any speed between 55-65 knots with flap down. I suppose that is because the 150 is a light weight trainer with effective elevator control. Certainly when flying more advanced and heavier trainers (the Harvard comes to mind), the glide was done at 10 knots higher speed at flare, to allow for the inertia.
