Hmmm. I investigated this sort of thing a few years ago. To get the PPL(H) with appropriate type rating you needed 500 hrs on type. Obviously at DHFS you dont get that on the Squirrel or Griffin and my frontline type wasn't on the civil register so I came up against a bit of a wall. I'd be surprised if the RAF made any significant effort to help with civil licence issue as it's not exactly an aid to retention.
If the rules have changed I'd be very interested to know if they apply retrospectively. Can you back up your rumours with any facts?
