AirAsia issue SYD today?
Heard an issue at Lunchtime, anyone confirm or have more details?
AirAsia A330 XAX223 departed 16R, shortly after tracked LEFT across 16L upwind as a QF737 was rolling and aborted.
Virgin 737 went around that was an finals to 16L.

Sounds like an ugly instrument failure, they Lost main NAV display and one Primary Flight Display, among other instruments (heard over ATC).
Looked pretty cool from where I was sitting to see a 330 takeoff and turn left from 16R. Caused a few collective gasps I can tell you.
Great job from ATC, especially departures. Kudos to that man. There was a brief pause while he and TWR worked out WTF was going on and then departures resumed as normal with a single controller managing Air Asia stooging around with no primary flight instruments and all the normal departure flow.
I'm guessing they headed to Melbourne due to the weather. It was reported as few at 3000, which was a lot better than the basically overcast at 2000 at SYD.
I'd still like to know why they turned left though. Even though the FMGC may have been saying turn left, self preservation should have kicked in and said, 'Turn right or at least go straight ahead -
away from the other runway.'

Incidents have occurred where the wrong runway was selected in the FMS for departure. If 16L was selected but the aircraft took off on 16R it would start tracking towards the initial waypoint aligned with 16L once NAV mode and the auto pilot engaged.
I'm not suggesting that is what happened on this occasion, but bear it in mind for future reference.

I seem to remember discussions that the One Engine Inoperative procedure on one of the Sydney runways involved a left turn after departing off the right hand runway. Maybe they activated that.
Damn lucky that didn't end up as a midair.
They will have to review SODPROPS after these incidents...................surely.
There wouldn't be a turn across an active runway, runway heading maybe?

While I think that sodprops are dumb and an incident waiting to happen, why would this incident trigger a review?
It was simultaneous parallel runway ops in use at the time...

With the initial right turn off 16R "as soon as practicable" but generally somewhere between 500'-1000' and cloud base of approx 2000', why would you turn left if still in VMC? Could be a very good reason not to chuck the autopilot in straight away.
The report should make for some interesting reading. Air Asia X obviously like to keep the ATSB busy!

If someone takes off and launches into a turn straight across the other runway you would have to ask how strong is the 'safety case'?
Not to mention someone with a control issue or a engine failure!!
I don't know how they justify it, but incidents like these show that it really isn't a good idea.
What Transition Layer said.
You're taking off from the right hand runway, the SID you have briefed says 'CAUTION: Parallel runway ops. Do not turn left'. You know there is a runway there. There is no excuse for turning left, especially in VMC. Like I said, looked pretty spectacular but they were very lucky.

SODPROPS (Simultaneous Opposite Direction Parallel Runway Operations) is the most efficient and "noise friendly" configuration. The landings turn off close to the terminals either side, the departure threshold of 16L is handy enough to the terminals (except for the departing heavies that require 34L), and most of the noise is over the bay for both landings and departures. This extremely rare "Xanadu" event is no reason to discontinue this optimum operation!
