Sorry if I've confused you Viz; I agree, maybe a trip to the experts might be in order - I'm certainly not an expert! But where are the experts these days?
In the post that you refer to, I was talking about someone on the PAS and AFPS75 (a rare breed) who would (I think you'd agree) loose any additional PAS pension benefits if he retired before serving for 5 years in the PAS. I understood that they would also revert to the CS (and thus loose half their flying pay) if they submitted a PVR within 5 years of joining the PAS, but maybe I'm wrong. If so, I'd certainly like to know!
