Self and a colleague (both ex RAAF instructors) dropped our log books into Melbourne CASA office recently and were given endorsements for aerobatics, low flying and formation flying. This was based upon our being qualified at the RAAF CFS to instruct on these sequences.
Another colleague - a retired former RAAF CFS instructor, was given an instant grade one rating despite not having previously held a civilian instructor rating. He proved a real asset at the flying school that employed him and his advice was eagerly sought by the junior instructors at the flying school.
Many years ago the RAAF awarded flying scholarships to PPL standard to selected Air Training Corps cadets around Australia. Forty scholarships per year were allotted. In each state a RAAF QFI was given the task of administering these scholarships with overall responsibility taken by the Command Aero Club Liaison Officer - a RAAF QFI based in Melbourne. He was required to hold a civilian instructors grading and carried out proficiency and resticted PPL tests on the cadets. The civilian instructors grading was given to him after a DCA flight test.
So really, when all is said and done, RAAF QFI's are perfectly capable to instruct civilian pilots to a competent standard
Having said that it does seem in present times that CASA FOI's lack consistency from region to region when it comes to awarding various civilian qualifications to RAAF QFI's.
In the early Sixties, RAAF CFS instructors from East Sale received invitations from the Royal Victorian Aero Club to visit Moorabbin and exchange instructor talk. This was very successful and the audience included civilian instructors of all grades from the other schools at Moorabbin. The idea was carried over to other states and a good time was had by all. It is a pity that such exchange of views has fallen by the wayside over the years.
