Thinking about it, the NPPL legal stuff gives Viggie guys cross credits for light aircraft and they have to do about minimum 10hours, pass all PPL ground exams and pass the nav and flying skills tests, that's without Aeros and spins. So that would be a start as its already sorted out what they do as minimum for civvy flying. They looked at vig when prop dropped off the Tutor for training new pilots apparently but loads of stuff it couldn't do so they will have that study they can use to see what Viggie guys need to learn I guess.
