The flying is not recognised if you want to put the hours towards a PPL as the syllabus is taught by serving RAF pilots,
Are you sure? I did my PPL after UAS, and I just had to do the exams, a bit of navigation, then the two PPL tests. I certainly didn't do 42 hours of instruction with a civilian instructor.
The LASORS set out credits from military flying towards CPL and IR, so it would seem logical that military flying also gives credits to PPL.
