Two different flights leaving the same airport at the same time???

[thompg]

I had a search and couldn't find anything about this (but I wasn't too sure what to type in the search box...) so apologies in advance if this has been answered before.

I was looking at travel.com.au and noticed that Qantas have a flight departing CBR at 10:15am heading to MEL, and then that Virgin also have a flight departing CBR at 10:15 also heading to MEL.

I thought it might be some weird artifact of the website, but upon checking the carriers' sites, those flights are supposed to be departing at the same time.

QF763 10:15 CBR 11:25 MEL
DJ262 10:15 CBR 11:20 MEL

Am I missing something? I would have thought that two planes couldn't use the runway at the same time. I don't believe that QF and DJ would codeshare?

Enlightenment will be gratefully received.

I believe these are the scheduled times meaning pushback from the gate and not actual use of the runway. No aircraft actually takes off at its scheduled time. hope this helps.

scheduled departure time has nothing to do with the time the aircraft will be using the runway. In Australia, flights are nearly always scheduled in 5 minute timeslots. In some countries they use 1 minute slots. The scheduled departure time is the time the airline targets to have to passengers boarded, doors closed and ready to be pushed back. The pilots have to request an actual departure slot from air traffic control, which cannot be requested until they are pretty much ready to leave.

Note that at some busy airports with parallel runways they do sometimes operate more than one take-off concurrently, but not at Canberra (with the possible exception of RAAF formation take-offs which would be rare from Canberra).

Does anyone know whether the times shown on Flight Stats are actual lift off times as against push back?
Reason I ask is that Flight Stats shows the two flights the OP referred to as departing within two minutes of each other today.

Scheduled: 10:15 - Mon 31-Jan-2011 Actual: 10:08 - Mon 31-Jan-2011 QF 763
Scheduled: 10:15 - Mon 31-Jan-2011 Actual: 10:06 - Mon 31-Jan-2011
With scheduled departure times of 10:15 the times quoted must be push back times I reckon.

There is a quote from memory that Flight stats is gate to gate.

QF763 CBR/MEL 1015/1125 Mon 31 Jan
left gate: 1006/took off: 1015/landed: 1115/arrived: 1120

Left gate is generally once brakes are released but time of push back could be a couple of minutes after that if an a/c is taxiing behind the plane, took off is when it's airbone, landed self explanatory, arrived when it's on blocks at the bay or aerobridge which as we know could be some time after plane actually touches down. :shock:

Reminds me of the days of TAA vs Ansett when "Parallel Scheduling" was a dirty word with each airline running almost identical timetables on the main east coast routes,
I remember the stories in the media about how the travelling public were being played as mugs and had little real choice.
