I have heard a new approach may be taken:
At promotion to Sqn Ldr all pilots will be slid onto a separate pay scale akin to PA with flying pay included in the pension (ala hooligans pay..). This guarantees a better pension for all.
Those who are promoted further will be subject to a taper arrangement where less of their flying pay is pensionable as they proceed through up through the ranks.
Whilst it is a rumour it has come from more than one (and independent) fairly reputable sources that this has already been considered but lost impetus as the retention figures improved and the flying pay review became imminent.
I have also heard that Navy Comd are involved and would probably implement but have some form of selection process (can't have all aviators dipping in compared to the fish'eds!).
This, to me, seems a wiser long-term approach to retention that the FRI. Whether those captured by the current FRI would be eligible during the handcuff period is an intereting dilemma.
Whether it is proposed at the flying pay review is a different matter...
