Great idea Dick, but unfortunately the AIC when it was issued allows for one aircraft in or out at a time.
Mate drives the QF B737 freighter in and out of YMLT and YMHB in the dark hours reckons it strange system. Me mate is old school and reckons that him and his FO can seperate themselves from the Metro and the Flying Doc drivers!
He reckons Melbourne ATC guys and girls do their best with the system they have.
Perhaps get a jumpseat ride with them or sit at the centre console and observe?
