NDW, youve got 2 different courses mixed into one. There is the Air Cadet Navigation scheme, all involving the Nav side of things and the Air Cadep Pilot Scheme involving the Flying side of it. Gaining your silver wings is not a strict requirement for gaining a place on a course, although it is a great advantage as it shows you do have a certain aptitude for it. Never get to complaced though. You hope to go solo next week.... not will go solo....
