I Like IT.
I've given instruction in both the military and civilian. I own and run a Flight School and am an Airline Captain and I think it's a great idea. I wish it was in place when I got off active duty.
A CFI certificate is a license to learn. Every new CFI has to go somewhere and instruct before they really get the big picture. Same for someone transitioning from military instructing to civilain. The military pilot with no civilian background will need to get back to basics on airspace, VFR sectionals, CFRs 61, 91, NTSB, AIM, and cross country flight planning. The new items to learn will be the required maneuvers for Private and Commercial check rides and of course getting to know the Practical Test Standards (PTS).
