Two planes have come dangerously close to collision, reportedly flying within 150m of each other over Queensland.

An investigation has been launched into how the AirAsia flight and a Jetstar plane came dangerously close to colliding at the Gold Coast Airport.

It's understood the incident happened on July 21 and saw the AirAsia flight take off from the airport about 11.42am.

The Jetstar flight was reportedly coming in to land when the two planes came within metres of each other.

The AirAsia plane was headed to Auckland while the Jetstar flight was arriving from Victoria’s Avalon Airport.

The Australian Transport Safety Bureau has since confirmed it is investigating the incident.

"The flightpaths of the inbound Airbus A320 and the outbound Airbus A330 resulted in a loss of separation," a spokesman said in a statement.

"Both aircraft received a traffic collision avoidance system (TCAS) resolution advisory...with the crew of the A320 conducting a climb to increase separation.

It’s reported the air traffic collision avoidance system had activated an alarm within the cockpit of each plane, alerting both pilots to the danger.

No damage was done to either flight.

A report from the investigation will be completed by July 2017.

As I read the text, the story is TCAS works, but the first half of the story "how did they get into the position to be in such close proximity?" needs more meat.

Why will it take 12 months for the ATSB to finalise its report? Seems an extrordinary long time to me.

Webtrak...

From LiveATC:

Jetstar cleared to 5000ft.

AirAsia was advised by the tower of crossing traffic.

AirAsia, on calling Approach (after takeoff) reported passing 2100ft climbing 4000ft.

Note: these are not all the calls made.

Interesting. while webtrak is somewhat accurate, I dont see the 150m miss touted. I also dont see much of a climb on the A320..and no dive on the A333....will be interesting to see if the A333 even picked up a threat.

note the scale on the last image...

What is the transition altitude? Looks like the kind of error you would get if 29.92/1013 was set too early.

Nice and high in Oz: 10,000ft.

A quick look at the WebTrak source data suggests that the minimum separation was approximately 3400 ft horizontally and 680 ft vertically:

Ian, same thinking.;) I had checked the QNH of the day: apparently 1014-5.

what about setting the wrong QNH?

As a private pilot it seams strange that they confirmed that they were climbing to 4000, if they had set it incorrectly?

Air Asia and OOL are never a good mix, fine weather or not it seems.
