Having completed PPL courses for many glider pilots it becomes very obvious that gliding instills a level of airmanship that is often way beyond that of the average powered pilot. That stands them in a very good position to complete the PPL course in reduced hours. There are of course skills that are quite different, and a glider pilot has to learn new skills that are not common to glider flying. The glide ratio of an aeroplane is much lower than that of a sailplane so the judgement is quite diifferent, but the glider pilot will have already learned more about landing in fields than the powered pilot ever will.
