The number of slots to earn your pilots license while in the Air Cadets is quite limited.Air cadets can earn their glider or small aircraft pilots wings. Most regions have a spring/fall glider familiarisation program. Depending on how close you are to an airfield, some cadet units have arranged famil flights as well.
It's a great thing to strive for, and the Glider Pilot program inparticular is pretty cool.
But going into the Air Cadets thinking they'll help one to get their license is...overly optimistic. It CAN happen, but the number of Cadets who want it vs the number of Cadets who get it is a staggering ratio
My 2 cents anyway
