I'm making a few assumptions here, Irish Tempest, but if you're writing policy and you're from Wyton, then I would suggest you liaise closely with: your contractors Chief Test Pilot, Boscombe Down Project Pilot's, AD/Flying and the eventual Cutomer pilots. From experience you'll find that each may have a different definition of, at least, all of Ghengis's list, and perhaps more.
I created a Flight Test Manual for work last year, and entered the minefield!
We're not that far apart geographically, if you'd like to discuss it over lunch, say, give me a call. I've sent you a private mesage with contact details,
