Pin Head,
You can't just go to an airfield and 'do an RAF Flying Scholarship'!!!! You have to undertake and pass a mini RAF selection process at RAFC Cranwell to be placed in the pool for award. Anyway, methinks you are way over qualified. The RAF Flying Scholarship scheme was set up to encourage young men and women (16+) to undertake flying training from AB INITIO level. The 20 hour course would hopefully entice them to apply for the RAF. (Although that's not what the official description says!!!)
It is certainly not an avenue to 'get the hours up'!!!!
Hope this clarifies the situ!!
