On the pre-SAFT
JP scheme, all pilots did a common core BFTS course of about 125 hours (if ex-UAS) or 140 hours (no previous flying training).
They were then streamed FJ/ME/RW and awarded their Wings.
AFTS was either Gnat/Hunter (Valley), Varsity (Oakington) or Whirlwind (Ternhill). After the Gnat/Hunter course, came the Hunter TWU course, then a FJ OCU - whereas ME and RW pilots went from AFTS to OCU.
If I recall correctly, Flying Pay was paid after graduating from AFTS - before then it was Flying Instructional Pay.
'Wings' were not confirmed until the pilot had been on his squadron for 6 months.
And it was a truly excellent way of training people...
