I completed the RAF flying scholarship the year before it stopped. It was contracted out to a number of flying schools - My friend and I completed at tayside aviation (now tayflite) - whilst another friend completed in uk mainland. The scholarship was for 12hrs. The RAF were considering down sizing costs by introdcing microlight flying scholarship, but decided against and stopped the scolarship.
Only other RAF subsidised flying for non military is the University Air Squadrons, but you need to apply and have interest in joining.
The ATC do not do a Flying scholarship - but do puch you towards Air League Scholarships.
Through the ATC you can complete a Gliding Scholarship and progress(GS), (AGT1), (AGT2), (G2), (G1), (C-CAT) and up to A-CAT 2*.
Also the Air Cadet Navigation scheme is available, but dificult to get I believe.
AEF - is Air Experience Flying - not a scholarship.
