The Aircrew Instructors' Course (AIC) at Scampton in the early 90s was a bit quicker. As described by the Course instructor, "We took the year long degree course to be a school teacher and removed all of the kids' psychology and namby pamby bits and expanded what was left into two and a half weeks". It was basically a Ground Instructors' GIT course but with the emphasis on briefing and demonstration technique. You graduated as either B1 or B2 and then had assessments later on the squadron/OCU to gain A2 then A1.
