Op Twenty - the FRI is paid at exit point not at 5 years to go, otherwise that would be targeted at 33 year old Sqn Ldrs!
Anyway, this one is to try a keep a little more than the 20-30% of senior officer pilots who stay already, the supposed future of the RAF. That said I do agree that Flt Lt aircrew after 10-12 years of service are probably at their most disillusioned/operationally fatigued so perhaps another FRI should be introduced for them (again), but as someone else said, where do we get the money from?
Well it is cheaper to retain than to train, so go figure.....
