Canberra,
An AAC ABFAC is in fact an NCO/WO/Officer. As a general rule, few Officers go down this route as they unfortunately get spannered with other"Officer" type jobs and can't spare the time it deserves. The task is mainly an NCO/WO preserve. I may be wrong but certainly, Cpl's have attended the course, the only thing is, I think they are held as limited CR until they achieve Aircraft Commander status and the subsequent promotion to Sgt that goes with that. In real terms that means they can only FAC under supervision.
