Why don't we just start with a feeder fix time given prior to take off. Why does an A380 that has been airborne in excess of 12 hours get a 15 minute delay into Melbourne. Or yesterday out of Sydney sitting at the holding point for over 20 minutes waiting to depart due to flight testing of navaids. This country really does need to look at itself. Start with a Royal Commision into AirServices and Casa. Christine Milne, where are you and you Greens, get real, all that Carbon needlessly pumped into the atmosphere due Sydney Airport political crap.
