I do believe I tried to pass on this little edict many years ago without success, and since I never saw a response, I will try one more time, just for my old Yankee mate, Ken Sunderland:
An Aussie grazier flew his antique Auster aircraft to Mascot Airport, Sydney, some time back to enact some business at the offices of business acquaintances. Not being familiar with controlled airspace procedures, although making it safely to the airport, he required and requested guidance to the GA parking area.
Much later, after the completion of his business and returning to the airport, he eventually taxied out to the major runway 16, again guided by ATC to take his place in the queue for take-off clearance. When finally cleared to line up and subsequently cleared for take-off, his instructions were to call “123 airborne” (the departure frequency).
Applying maximum power and concentrating on keeping his aircraft on the centreline on the roll, the tail rose, and soon after the aircraft became airborne, whereupon the pilot pressed his transmit button and called … “1-2-3 airborne”!
