(c) A pilot who manipulates the flight controls of an aircraft under actual or simulated instrument flight conditions solely by reference to instruments and without external reference points is entitled to be credited with the instrument flight time acquired in this way towards the total instrument flight time experience required for—
(1) a higher grade of pilot licence; or
(2) an instrument rating; or
(3) the recent experience requirement of an instrument rating already held.
The above is copied directly from part 61 in NZ. I'm guessing it must be different in Oz. I have only about 6% of my total time as IF, despite 90% of it being conducted under IFR. My reading of the above is that it is legal to log the whole flight as IF, regardless of autopilot or weather conditions. As long as you do not navigate by looking out the window. Which I do not. It is simply tradition that anything over 10% is considered fraudulent. Am I wrong?
