Hmmm. So your lift to the hover prior to hover taxiing to the departure point for take off is your take off? Maybe too much time spent on wheeled machines crab@
Your lift to the hover is your take off - it is a helicopter after all - your departure is your departure whether straight from the hover or after taxying.
I am flying 2 skidded types at the moment at a civil airport and the nice man from ATC lets me air taxy to the runway (I have left the ground so I have taken off) and then clears me for departure, not take off.
Or do you not count time spent in the hover as flying time in Oz?
