I have just lost my flying med cat permanently, now A4. I am also permanently non deployable amongst other restrictions. I am moving into an established ground role for my trade as well as being allowed to serve for the rest of my engagement (aged 55). Because of this move, I am keeping my RRP (flying pay of old) as well. Manning have been very supportive throughout.
Clearly I am not on PAS, but in terms of engagement and pay I am not losing out at all.
And before people chip in and accuse me of shirking or causing others extra heartache, I have nearly 800 days OOA and my injuries were caused on duty.
