On Thursday 14 July, depending on turnaround times for inbound aircraft, there may be some delays to the morning A333 QFi scheduled departures for points in Asia as quite a few flights (see above) were well over an hour late departing on Wednesday 13. Some have become even later, with for instance the Wednesday night arrival time of QF19 (above shown as 2040 hours) now put back to around 2120 in MNL. Inevitably with the minimum observed turnaround times for A332/A333 aircraft on international flights being c. 65 minutes, there will still be extensive unpunctuality among the Thursday morning arrivals.
ATC is no doubt expert at dealing with out of sequence aircraft arrivals in SYD (which happens every day) but there is a mandated limit of 20 aircraft movements per quarter hour along with the much better known 80 movements. As we discussed many pages back, at times these two caps can in a sense 'contradict' one another in that (presumably lower priority departing, as opposed to higher cab off the rank arriving, aircraft) may have to wait for a particular quarter hour to tick over before being granted clearance for takeoff. The inefficiency of this rule must cost airlines (not just QF) quite a deal and its irrationality might be at least a minor cause of frustration for airline passengers and staff, including tech crew who would like to get on their way.
QF35 on 13 July departed MEL at 1433 hours, two hours and 48 minutes late with SIN arrival exactly two hours tardy at 1955. QF82 from SIN is expected to depart at 2125 hours, 70 minutes late for a Thursday 14 July SYD arrival at 0645, 35 minutes behind schedule.
