As he said above ^^^^
Being paid close to a Wg Cdr's wage to do a staff job as a Flt Lt or Sqn Ldr isn't all that bad. Also, 'general list' (or whatever they call them) Sqn Ldrs usually only get one flying tour as a Flt Cdr, so they don't have the same opportunities to go back to flying as PAS.
So, suck it up, it is part of your TOS and when the RAF are short of aircrew with your skill set they'll be sure to return you to flying.
