Bit of a whoopsie from an EK A380 last night operating as EK435 BNE-DXB.

Was cleared to taxi to the A1 holding point for RWY19 via B, but somehow ended up missing the right turn onto B1 & continued straight onto taxiway D which is a different width & weight classification than taxiway B.

I hear she ended up taking out some taxiway edge lighting and tore up the pavement a bit. Took a bit of an effort to push it back onto B!

Funny how this one kept hush hush & my colleague in TSV wasn't aware of it either!

Oh dear.

Another FD crew out of a job? Probably.

Incident on your record? Then you're unemployable these days.

I would prefer to have someone on my books that has had an incident or two. It's the people who have never made a mistake that worry me. First mistake can be their last?

Most of it is down to poor and penny pinching training.

Wonder what additional charges BAC will now place on all operators due to this incident? A 'pre taxi' charge just in case someone takes out some lights once or twice per year? $0.65 per pax should square that off nicely.
And I wonder what BAC are charging for the repair work? $3,000 per hour spread over let's say 120 hours of streeeeeeetched out repair work?

Rest assured, THERE WILL BE NO REPORT SUBMITTED, to do so would be anal. In line with ASA's new relaxed attitude toward their customers they've classified the incident as minor. The ground controller was heard to comment 'ASA's got my back, CASA don't give a **** & ATSB only investigate bus crashes, sweet. I had a few beers with the FO last night but he had to leave at 6pm as the security dood threaten to kick him out if he fell asleep on the table one more time'

Just as well the incident didn't involve phraseologies, that would be a different kettle of fish ;)

On a related note...let's give credit where it's due.

The GIG pilot(s) were treated very professionally and the Safety Dept conducted itself as it should without Fleet being overly involved.

The end game was as good as it gets, considering the circumstances .

Wishing the same for our brothers in BNE.

I'd be interested to know how many other times pilots have missed this intersection. Bet it's not the first time. I've seen some interesting skid marks on taxiway B northbound in the past where someone has obviously realised very late that they were about to go into no-mans land.

They are not the first aircaft to do this. I've heard at least 3 others have done the same this year alone.

Maybe the installation of some sort of 'Hold Short' flashing lights to alert crews might be in order?

Knowing BAC though, it'll be 2020 before they install them and then every aircraft will have to pay in the meanwhile to fund them! :ugh:

And its not the first time for an Emirates aircraft in Brisbane either. A couple of years back now, we were taxying out at night for a 19 departure to SYD, and ATC (unusually) flipped us out to taxiway A. Approaching the holding point, to our amazement, an Emirates 777 had cornered itself on taxiway D. Apparently it was there for some time before a tug could be organised. At night, wet, unfamiliar, and you let your guard down... you could imagine how this could happen.

Taking the wrong taxiway, lining up on rwy edge lighting, lining up on closed rwy's even ldg at the wrong drome, all part of aviation & risk management. The big ticket item here is the guy behind the steering wheel as you can have all the best training in the world, all the fancy gizmo's in the pit of cocks, all the CRM crap you can dream up as well as all the other feel good words TEM being one of them all means Bear Poo as we are humans not machines & fatigue & distraction will always win at times.

So you two who believe human pilots are a problem forget that the programmer who writes the software is also human, and has much less-self interest in getting it absolutely right than the pilot who will be first to the scene of the accident!.

Korean Air did exactly the same thing in BNE not so long ago in a 'bus. After a spate of these (another one in BKK) occurring they have fixed the problem. No really, they have. Lots of extra talk talk in the cockpit so the likelyhood of missing a call goes up. No problem they will invent another procedure to fix that if it happens. Funny thing is they did it again at home base the other day in a triple!!!

As said I think we have all missed a taxiway once or twice in our life time due to many reasons, usually no big deal. But unfortunately due to the poor design of this particular taxiway in Brisbane where an international width taxiway turns into a GA width taxiway it has caused more interest than it really should have.
If a Chief Pilot can do it what chance have us poor mortals got! :ok:

How do you miss a taxiway with a moving map gps display and signposts? If you're paying attention to whats going on I have difficulty accepting that you can miss that taxiway when the map in front of you shows you where you are and shows the taxiways and they're all signposted. But if if you are in the dark with some dodgey half ripped jepp chart its a different story.

I " shudder " to think what if another aircraft taxiing behind EK435 had followed her into TWY D as well when they received taxi clearance from lazy controllers : " taxi to RWY 19 to follow EK A380 ahead of you "

That taxiway has a long history of people missing B1. I can remember at least two Ansett incidents and I nearly did it myself once on a 727. I'm not sure why, but it is easy to do, it looks like the runway threshold is further down for some reason.
Recently, on a cargo run to a Pacific Island we had a load which included small-arms ammunition and marine flares. The safety security clowns confiscated a tube of toothpaste from one the crew. We were all X-rayed, bomb sniffed, covered in bright yellow vests, prodded and poked, cameras watching our every move, including on the tarmac. Shame the airport has a real safety issue and we can't even get a 10 dollar sign painted on a taxiway.

Yeah, two years ago had a death on board 400nm south of Perth enroute to Brizzy.
Security would not let the ambo's in to collect the body on arrival, as they had no ASIC ID.
Over an hour later they arrived.

Yes humans are fallible but if you are not distracted and paying attention how do you screw up with moving a map infront of you? Yes you are probably tired, yes its a tricky taxiway, but the moving map should prevent this.

Wally Mk2

'Nev' over reliance on technology can be an issue. Those fallible humans are wired in ways the so called CRM goons have no idea about & never will.

Why does a well trained pilot whom is rested, all up to date with his/her training has an excellent past re incidents/accidents simply fly into the side of a mountain accompanied with more technology than ever b4? '..............sometimes there's just not enuf rocks'.................Forrest Gump:-)

I hear she ended up taking out some taxiway edge lighting and tore up the pavement a bit. Took a bit of an effort to push it back onto B!

There is no TWY edge lighting at BNE, the pavement was not torn up (TWY closed for a while pending engineering assessment) and it took no effort to push it back using the appropriate tug (issue is finding said appropriate tug and then getting it from effectively one end of airport to the other). I suggest you check your sources.

EK was not the first to overshoot B1 and they won't be the last.

I'm not sure why, but it is easy to do, it looks like the runway threshold is further down for some reason.

Can't see how this is so, as by the time you get to B1 the RWY 19 Threshold is effectively behind you. More likely they look up and see the RWY 32 threshold more or less directly ahead and just keep going.

A simple red sign saying "RW 19 threshold NEXT RIGHT". Our French Cousins write such signs on the taxiway itself, just like road markings. When I first saw these at CDG (Paris) I thought they were great. Not only that but fairly idiot proof and cheap. I'll even lend you a paint brush.

If we want to be slightly sarcastic, we could state that obviously moving maps and all the modern gimmicks don't help. Statistically this overrun of a A380 shows (at this moment), that an aircraft with such a gimmick is more prone to mistakes than the ones without (A380 movements in BNE vs mistake compared to i.e. T7 or A330).

I know, I know, it's just statistics and the A380 is a young fleet, and blah, blah, blah. Simply wanted to make you whale-jockeys jump!

Hotspots exist at many airports. We might reconsider implementing all the electronic bs that exists, it could turn out to be counterproductive. We need the jockeys to look outside to keep the big picture, up to today it is still there where it happens, not on the fancy screens.

And being in the famous down under region, we might consider a little fewer and shorter briefings, as to keep the pilots capable to concentrate to what happens in the real world, right now and outside.

Leave the superfluous talking to Ted Cruze .....

The pavement at the entrance of D is painted with the sign MAX TOW 56 000KG (or something fairly similar) but that hasn't worked either, and nor is it visible at night. The red sign sounds good.

What are you doing briefings on taxi for?

doubleu-anker
18th Oct 2013, 08:49
Long, complicated, boring briefings.

In spite of all the gear and technology available to the crews these days, there is a tendency to loose sight of the basics. It's getting overly complicated and the move away from the basics, is becoming more apparent.. We as humans can only take so much in for recall, at a given time. As queried T/o and Dep briefings shouldn't be done when the aircraft is taxing. Amendments/changes, maybe with caution. Should be a 2/3 crew full time job with as many "eyes out the window2 as possible. This of course is stating the obvious.

The is a European aircraft manufacture, who have such an avionics fit for to their aircraft, it requires a whole new type rating to operate it. Where is the simplicity in that? EASY I think they call it.

When I started on heavies, I sometimes flew with an ex WW2 pathfinder. The t/o brief, when he responded was to point his finger up, accompanied by the confirmation of the MSA. Landing brief was finger pointed down, with the confirmation of the MSA. Worked for us.

Gimme a big K.I.S. :)

According to a mate, who also knows the Brisbane & Townsville refuellers, and just happened to hear much of the R/T exchange, much of the delay was getting agreement from the tech crew to shutdown some of the engines so that safety personnel could walk around under & behind the aircraft to check for pavement damage before it was towed out.

His recounting of the story was so amusing its sad that he's not contributed to this thread. :\

What are you doing briefings on taxi for?

You might read the OMA and FCOM of a lot of mentioned operators in reference of

- runway change
- T/O clearance change / initial issue or reissue
- change of weather conditions
- take-off reviews and similar re-re-re-re-doing of already done

to understand the overkill of babbling, finger exercises during taxi

Hence this hint of how such incidents can be reduced ...

True. However, there's been a few of these incidents so maybe something could be improved.

There's a whole winter wonderland of yellow mag signs at that intersection and when someone's unfamiliar with the intersection and/or distracted, maybe they all just turn into a blur.

'Nev' couldn't have said that better myself! Companies don't want pilots they want puppets whom jump when told to, having a pilot 'think' outside the square in other words being an actual pilot is something that has no place in modern day company Ops!
Having a think about the taxi instructions to said Rwy 19 at Brissy if I recall such instructions are for Eg clear to taxi via C4, B & A1 holding point (or words to that effect) for Rwy 19, trouble is there's a B1 to be negotiated on that route before arriving at the Hld point, perhaps that's a missing trigger for some whom might be distracted & it's easy enuf to do that seeing most of us here are human!

BTW OMA might be a typo, AOM (Aircraft Operating Manual for Boeing) might be more the case here.

Certainly nothing new there.Seem to remember a fully loaded 727 ( not quite as dramatic as an A380 admittantly ) doing the same thing not long after the present BNE airport opened way back when.Crew and ATC realised at about the same time I think.Same result. Shutdown on the taxyway and a tug pushback onto the correct one. Very easy to do in BNE even today especially for a crew unfamiliar with the setup and more so at night.Maybe they need a really big signpost !

21st Oct 2013, 08:06
When I nearly did it I think my mental model was that I would reach the end of the taxi-way when it was time to turn. I guess this was due to being too relaxed and not diligent enough.
I'm obviously not the only one to make that mistake. I'm not certain that was the reason, just a best guess at how I made the mistake.

23rd Oct 2013, 05:34
For those of you who have some influence here is how to make it better in Perth Brisbane and Sydney:

Put large painted taxiway designators on the centrelines at taxiway turns and intersections (in addition to the side markings).


For me, Auckland is a great example of how to do it properly.....google map it and have a look at the designators on the taxiways.

Traffic_Is_Er_Was
24th Oct 2013, 15:17
Unfortunately most of the over runs seem to happen at night, so painted markings are not really of much use. The only real way would be to extinguish the TWY lights leading onto to Delta past the B1 turn, but that would mean either turning the lights back on when they are required, or forbidding movement in (only) that direction at night on that section of TWY D.
Funny thing is is that no one has yet overshot the B into B9 turn at the other end (admittedly not used very much).

What about 'follow the greens' like they have in SIN and LHR amongst other places?

Ahhh - Brisbane Airport

Where it takes longer to build a new RWY than the entire duration of WWII.:ugh:

Taxiway signage may take even longer.

New multi-storey car parks we can throw up in no time however.

Maybe the new Govt's "Direct Action" climate plan could force them to build the new RWY at "china speed" - that would save X,000,000 tonnes of CO2 emissions.

Funny thing is is that no one has yet overshot the B into B9 turn at the other end (admittedly not used very much). Actually I think there have been a couple, but they just taxied into C10 and back via the international apron so there wasn't any hoo-ha with tugs and pavement issues :suspect:. The worst thing they copped was a ribbing from the tower.

If an A380 did it it could get a bit untidy, but IIRC they can now use the L/P turning loop. If I've got that wrong they'd possibly need to get towed back, but unlike TWY Delta the pavement is still rated for their weight so it would just be an inconvenience.
What about 'follow the greens' like they have in SIN and LHR amongst other places? How does that work?

In SIN and LHR the Controller can light up the dedicated taxi route, tailored to the clearance. All the troops then have to do, is ''follow the greens". I often wondered how much traffic it could take without conflict, but it always seemed to work ok. I hate to say it, but a few pilots still got it wrong. The trouble with large Long Haul Operators, is their networks are so big, it's not uncommon to go to a place only once a year. You never gain 'local knowledge'.
These experts that say, "just look out the window'' wouldn't last five minutes in somewhere like Chicago, especially at night in the rain with ''Yank Speak'' at five hundred miles an hour. Taxing around is where most mistakes are made.

Thanks for that. :8
As Traffic said it would probably work most of the time, but not when RWY 32 is also in use with GA and domestic turboprop traffic simultaniously taxiing for Delta.

.......but not when RWY 32 is also in use with GA and domestic turboprop traffic simultaniously taxiing for Delta.

The 'follow the greens' system is tailored to each taxiing aircraft so as one flight deviated from the common path the greens illuminate correctly for the next aircraft. So as the domestic turbo-prop continued straight ahead at 'D' the lights would switch indicating a turn onto 'B1" for the following traffic.

Given most airline operators taxi a reasonable distance behind the preceding traffic, they should have more than adequate time to recognise that the greens go 'round the corner.

I'm not exactly sure how it works (i.e.: does it use transponder or other wizardry.....) but the system in Singapore is virtually fully automated or that's what I was told when I visited the tower some years ago.

Wow, that sounds amazing. :8
Thanks for clarifying the term.

Eclan,

If he's paying attention to driving then he shouldn't really be head-down

I agree with you sentiment but taxiing the dugong does require quite a bit of head-down using the camera display on the PFD to confirm correct over-steer and the moving map is definitely part of the scan though was perhaps deselected approaching the holding point.

Eclan's ethos is at one end of the scale, it relies on crews not making mistakes. At the other end of the scale is designing a system where mistakes cannot be made. Each is as unachievable as the other. Somewhere in the middle lies the most effective solution.
Solid training with regard to discipline and communication, briefing etc ( airmanship as Eclan called it), combined with identifying weak points in the system ( the taxiway being discussed) and altering the system where it is not working so well. This also applies to the YMML 34 Sheed arrival being discussed on another thread.
Upshot? We need to invest in training while continuously assessing the systems for weak points and then addressing them. Pretty much common sense really. So why don't we do it as well as we could? One word. Motivation.
What motivates our industry leaders? They are the people who can easily assign the money to both training and system changes. Our CEOs are motivated by money, remaining competitive, shareholder returns etc. I'm not saying this is wrong, it just is. They will only part with the minimum amount of money that they think they can get away with for training and infrastructure updates etc. At the moment in countries like Australia the only reason we have the level of training expenditure we have is because it is legislated. That is the only means of providing motivation as these folk have legal responsibilities and personal drive to make the money.
So unless it is legally required it won't happen because it would put the company at a disadvantage against it's competitors.
Motivation for improvement is the answer, the motivation that works is legislation. Eg we all pretty much agree that airline pilots need to spend some time hand flying simulators to become comfortable with this skill that is being lost, no airline that I know of would allocate two hours of sim time every six months to hand flying unless it was law. In my mind it is as simple as that. If you want it, require it, otherwise it won't happen.
