When No1 son did his RAF Flying Scholarship in '86 I think it was for 35 hours and I paid for the extra 3 required to obtain the licence, which I don't think he has ever used!
Mine was for 30 hours (5 more needed to a PPL/A ) which I never actually obtained due to a few setbacks (one of which was joining the RAF). I then went straight to a CPL/A 22 years later. Same with the PPL/H, never actually held one, went straight to an ATPL/HG. EASA took away the /G though, last time I renewed my licence.
