There is a Flying Scholarship scheme within the ATC that is alive and well. The RAF withdrew their Flying Scholarship scheme in recent years, however HQAC responded and started a new scheme.
The following courses are open to ATC Cadets;
Air Cadet Flying Scholarship (Light Aircraft)
Air Cadet Flying Scholarship (Microlight)
Air Cadet Flying Scholarship (AEF)
Air Cadet Pilot Navigation Training Scheme
As well as the usual Gliding Scholarships. The Light Aircraft Schol. is 10 hours of flying done at a Civil flying club. I am not entirely sure of the Microlight scheme , but the Nav. and AEF Scholarships are done on AEF's.
It is also worth looking to the Air League and GAPAN for sponsorship.
