there are a number of 'young' navs who will no doubt be more encouraged to PVR now, based on the fact that the will have to wait a year to leave. The RAF has yet again screwed up its manning and with it its man management, they hear that nav are disillusioned with nothing on the horizon for them and so they make it harder to leave but offer nothing in return. Not that many would do it, but you'd struggle to make a case for arguing against them not being 'fit to fly' due to stress of losing about 1/4 of their pay overnight too, also i assume they still have to deploy?
