TCAS at OOL JQ630 vs D7206

[Quickstatus]

TCAS notification to both aircraft sends JQ into climb.

JQ630 on approach from AVV and D7206 on departure to AKL
Unfortunately FR24 does not outline the scenario and CASA is investigating.

Both airlines operated to the south on runway 14

Did D7206 stray onto the runway while JQ630 was landing?

However and as usual the Courier Mail were able to "accurately" describe the scenario::shock:

First up, let's put that image into perspective. It's total bulls**t.

Their point of closest approach was at 01:41 UTC, at which point they were both about 5 miles to the south east of the field (off Fingal Head).

Air Asia had taken off to the south, and turned left towards NZ, and was climbing through roughly 4,000 ft. Jetstar was northbound, on descent, and at about 5,000 ft. Looking at FR24, Air Asia never stop or reduce their climb rate. Jetstar, may actually have been level at 5,000. The resolution of FR doesn't really show a climb.

In any event, with one aircraft descending, and the other climbing, the TCAS will go off, even if there is an ATC step between them.

I'd suggest waiting until the ATSB has their say. This could be a case of someone breaching altitude, but it could just as easily be nothing.

Minor detail but CASA doesn't investigate, it's the ATSB that does...

From pprune - slightly different to the Tele

Vertical separation of at least 250m, plus whatever horizontal separation.
Reportedly AirAsiaX aircraft under instruction to maintain visual separation

Click bait bs vs facts. We all know who wins.

JQ was landing, so why does the "original flight path" show as a climb? Typical tabloid journos (although, unfortunately, Australians seem to buy it).

Seems as though it was just an unfortunate situation. High climb rate triggered an RA that may not have been needed, however the system only works because crews have to follow it.
