Are you on holidays with nothing else to do?
I don't work for JC so how would I know.

..........hey 'jaba' I know they are mostly 'tin' as you say it was said with more tongue in cheek as most see the home builts as made of plastic, fiberglass, foam & wood etc (like my toy planes) hence the 'stigma' attached from days gone by/bye/bi:-)

Are you on holidays with nothing else to do?

Yep, school finished 2 weeks ago.



2 'River Track' arrivals 20 minutes prior

Looked a completely normal visual approach pretty well by the river track.

I don't think so

[GAFA]

There is no river track from the south, so QFA 126 didn't fly that arrival. The visial approach from the south takes you just to the left of the Gateway (overlfying Cannon Hill) turning final the Gateway.

The last pic of QFA126s track looks like he started out on the ILS and then tracked to the north to miss the weather and carried out a visual approach from the north.

[megle2]

No one said he "flew the river track" rather he flew "pretty well" the river track, meaning he was close by, ok.

[Keg]

I wonder if we can do a BUMET weather radar overlay for roughly the same time (it'll be up to plus or minus six minutes I presume). That would certainly be interesting.

He's well inside the river track. Even allowing for some lateral error on the web track he's probably still well inside it. The go around (can someone occur that's what actually happened?) looks like it may have been due to not being lined up with final by 500'.

Interesting.

Stallies questions interested me to look a little further.

You don't know how accurate the position is laterally

(all of these can be verified by listening to the ATC tape link - 3.6 mb)

At 05.05 local time, Rescue 500 lifted of the Jackson Oval on Russell Island (20nm from YBBN) with a med 1 for the PA Hospital.

Lateral position accuracy - check

You don't know how accurate the altitude figures are

The next radio call after QF126 GoAround, report was Rescue500 maintaining 1,500ft. (450 m)


Altitude accuracy - check

You don't know the refresh rates

4 seconds, you can time them yourself

You don't know what the crew could see out the window

5 minutes before the GoAround, ATC broadcasted a TS warning "3nm to the east and south" and again as QF126 approached 1,000feet "it's coming down right overhead from south east to northeast and it's at the boundary of the airfield now" Listen to the first 5 minutes of Kegs tape link.

You don't know what kind of instrument approach (if any) was flown

Obviously a Visual Approach, because there is no instrument approach within a Bulls Roar of the track flown by QF126

You don't know the airline's procedures

Correct - But I question any procedure that has the aircraft not 'stable' till 200ft.

Save the approach stuffup analysis for a FOQA analysis or equivalent

Jetconnect, whilst being a wholly owned subsidiary of QANTAS, has a NZ AOC. Will, what would have rang alarm bells loudly in the QF mainline FOQA protocols, ever see the light of day with Jetconnect? I don't know but I've put it on here with only info available in the public domain. It's up to you whether you care enough about what went on.
