High drag aircraft such as what Frank and I have don't require power for a smooth landing following a steep glide, but they do require very precise speed management and timing. It takes discipline and a lot of practice to keep the nose pointed at the ground until you are practically on the runway before breaking the glide and greasing the landing. You only get one chance for the smooth landing before airspeed decays. Carrying just a little power vastly increases the size of the airspeed target and makes landings much less.....exciting.
A bounce occurs when the plane is flared too high and airspeed and inspiration are depleted at the same time.
