MU Plane Took Off W/O Clearance & Despite Stop Order

Mon Nov 28, 2011 8:31 pm

OK, confusing a Line Up and wait clearance with a take off clearance, I can understand.... but continuing the take off roll when the Tower says "STOP" is beyond my understanding capacity ( unless they were already at a very high speed...)
Anyone has more info about this ??

It was a China Eastern A 332 from Osaka to Shanghai

Take offs without clearence happens now and then. Standard ATC phraseology has been constructed to minimize the risk here. The worlds worst air disaster was caused by a KLM 747 taking off without clearence. Confusion can be minimized with use of proper standard ATC english and good knowledge of the english language.

There are new English tests for pilots who fly international legs which should help to stop this kind of thing happening.
and with that..cabin crew, seats for landing please.

I'm not so sure I can. Even if you have basic knowledge of the English language, "China Eastern 516, runway XX line up and wait" doesn't sound a lot like "China Eastern 516, wind xxx at xx, runway XX cleared for takeoff." But then again, who know what else was going on in the cockpit from CRM on down...

The pilots need to be suspended immediately, and perhaps fined.

Why not fire them too? Departing without take-off clearance makes them a hazard to other aircraft.

Umm. No. V2 is takeoff safety speed. The speed typically flown in the event a one engine inoperative situation occurs.

You were thinking V1, the aircraft must be able to stop on the remaining runway prior to and including V1. Just because the aircraft was still on the runway doesn't mean he was under V1. So false on both accounts.

Of course there will have to be an investigation. There could have been confusion or misstatement in the ATC, tower, or by the pilots on the a/c allegedly involved. I am quite sure the Audio recorders in both the airplane in question and in the tower will be able to help figure out what happened. I do hope the airline takes some action on these pilots, mainly suspending them, and does their own investigations to see if there is a problem in the training and rules as to these pilots. We also need to know if there were airport curfew, duty hours, and related issues that may have caused the alleged unauthorized movement without clearance.

Who is to say it wasn't the controller that didn't clearly enunciate the words correctly? If the controller has the issues, he/she may cause more incidents like this in the future. Perhaps it is not the pilots at fault.

I teach Chinese flight students and while I'm fortunate that my students are pretty good, I see a lot of issues when the Chinese have issues understanding an unfamiliar instruction. It's not their fault, it's just the way they have been brought up, they are very, very good at memorizing, but when it comes to critical thinking, that's where they often come up short. I'm not saying they're all like that, (my guys are pretty good) but a lot of them are.

This video shows the mentality of a lot (again, not all) of the Chinese pilots.

On a more serious note, is this the same airline that drove an A300 into the dirt maybe some 10-15 years ago and the pilot is heard on the CVR asking the FO, "what does it mean..PULL UP, PULL UP?" I think that anecdote was in the Foreword of a book on CVR transcripts. Not light reading but pretty sobering nonetheless. Pilots can get distracted, face language barriers, make simple mistakes, or be grossly negligent.

These guys are lucky. It could've been foggy or raining with another aircraft on the runway but out of sight until too late. Just when you thought another Tenerife could never happen again..

Our SOP is abort above 80 kts is only for Fire, Failure, Roll back or loss of directional control. A controller saying "STOP" requires a very quick judgement call. An aborted take off at high speed (in our case over 80 kts) is one of the more dangerous maneuvers you can do in a jet. If the crew cannot see an obstruction, imminent collision, or some other catastrophic problem, its probably best to keep going.

IMHO it is much safer to continue the take off and avoid the helicopter traffic that the Japanese controler was worried about. But I don't think anyone on this forum was actually there, so this is all just standard A.NET armchair quarterbacking fun....

Anyone listening to ATC at large airports know Chinese pilots, on average, have a very very poor grasp of English. Add Japanese accented English, and who knows. Add the general poor aptitude for flying most Chinese pilots have (saved only by the extreme automation thanks to airbus), and it's easy to see how this happened.

After applying take off thrust and after IAS 80 knots pilots typically do not take any external orders and ATC are normally instructued to be silent until the plane is safely in the air. I think this applies even if the plane takes off without clearence as long as there are no obstacles in its way... An interuption could be a serious hazard and distraction for the pilots. When the plane has finished the take off procedure ATC comes back with frequency change or whatever but it is common sense to let pilots concentrate on the take off. I would guess that if the take off roll had progressed pilots would not have listened to any stop order.

But chinese pilots are not known for their language skills and sometimes they even have/ had? a separate radio operator onboard to help pilots operate on international routes even if they lack basic english skills. Extraordinary but 10 years ago it happened, I do not know if it still happens. Chinese airlines have a way to go to come up to international standards both when it comes to operations and communications I think.

So glad we changed the standard phraseology from "position and hold" to "line up and wait" specifically to avoid situations like this! It seems to be working perfectly!   

The phraseology really needs to be looked at here. "Taxi into position and hold" is impossible to mistake for "clear for takeoff". Even if the phrase "hold for takeoff" is used, it is impossible to mistake the word "hold" for "clear" regardless of pronunciation.

Some of us were arguing when this change was made that something just like this was inevitable, and it's especially likely in non-native English speaking countries where it seems only the pronunciation and misunderstanding of a single word - "wait" - was responsible for this incident. It's just lucky that no other planes were on the runway at such a busy airport.

I often listen to Manila and Singapore FIRs on HF and the Chinese are definitely the worst, closest following by the Korean's. I could probably fill an entire hard drive with audio clips of heated exchanges between ATC and the crews because the crews can't understand basic instructions. Weather deviation clearances can go on for many minutes as they try time and time again to read it back correctly.

The flight has changed to a 737 now where the crews have a reasonable grasp of English, but going back 12 months+ when CZ388/7 CAN-CGK-CAN was an A321, there were a couple of regular crews that always seemed to be on that run that simply could not pronounce any English at all. The best they could manage when saying the callsign was "Tanatudda fe-ay-ay". 80% of the time it would result in MNL or SIN asking them to spell their callsign phonetically because they simply couldn't understand what the crew were saying. Crazy...

The Chinese 737 delivery flights from BFI to Hawaii are always a laugh a minute on the NPAC as well. SEDAR ZANNG ZAGER ZINNO ZEMON ZOULU ZIGIE is the usual routing, but they pronounce each one exactly the same when giving their AIREP. San Francisco ARINC radio operators are INCREDIBLY patient people, it has to be said..

Even if the phraseology is changed and seems to work someone could make a mistake anyway. So if you change phraseology everytime you have an incident like this you end up with changes all the time. Just one mistake is not always an indication there is something wrong with procedures or phraseology. There could be other problems.

By the way it seems non english speaking pilots function better verbally with non english ATC since they tend to stick to standard phraseology. Also UK ATC is pretty diciplined which is good for the understanding. However some american ATC tend to complicate things by deviating from standards both in COM and procedures, The more standardized the less room for misunderstanding in an international environment.

I'm not so sure I can. Even if you have basic knowledge of the English language, "China Eastern 516, runway XX line up and wait" doesn't sound a lot like "China Eastern 516, wind xxx at xx, runway XX cleared for takeoff."

If you look at the two phrases in your example, not only does about half of each phrase "sound a lot like", but they are 100% identical! ("China Eastern 516", and "runway XX")

It might look distinctively different to you while the text is read on this nice blue and white Airliners.net text field, but when being listened to when English is not your primary language and its spoken to you by someone who's primary language is not English... it may not always be so blue and white when considering the many other issues/distractions which may have been going on. Especially when half the words of these two very different clearances are the same.

Again, of course its possible. Furthermore, the word "takeoff" should never be used when communicating with ATC (clearance delivery/ground/tower) before being cleared for takeoff. "Departure" should be used. "Hold for takeoff" is a bad idea.

Personally I thought that the pilot handled those comms really well even though his spoken English was poor. The ATC was just as bad as the pilot, calling him "Air China Freight seventy six heavy" for the duration and very slack ATC phraseology in general.

The flight callsign is Air China Freight 1056 [Heavy].

Listening to the tape again, that's exactly what he was saying. "Air China Freight ten fifty-six heavy."

Quoting spacecadet (Reply 30):
The phraseology really needs to be looked at here. "Taxi into position and hold" is impossible to mistake for "clear for takeoff". Even if the phrase "hold for takeoff" is used, it is impossible to mistake the word "hold" for "clear" regardless of pronunciation.

Totally disagree.

We're veering OT, as it's not established that phraseology had any cause or effect on this incident.

Reference some years ago, stuck behind a JAL B744 at LHR, who was instructed to "Line up and hold," to which he replied "Roger, Line up and ROLL."

The modulation of accents and speed of speech on the RT caused the mistake, not only by the crew, but also ATC who didn't pick up on the incorrect readback. A nudge to the TWR that the Japanair misread the instruction prevented a similar incident occurring on that occasion.

It happened a lot, especially with asian carriers, and will still happen if non-standard phraseology maintains to be used by cowboys who think their way is better.

It's standard, so use it

Quoting Mir (Reply 37):
but "Air China seventy six heavy" is absolutely correct).

Make your mind up!

Quite simply this proves what I said. US ATC phraseology is abysmal. I was born here in England and am - unsurprisingly - a native English speaker and at times even I struggled to understand the instructions being barked out by the ATC in the audio, so what chance does a non-native have? As I said, I think the CAO pilot did very well under the circumstances.

I know that the trip number is 1056 for that flight but it sounds like the ATC says seventy six heavy in every communication in the audio clip. I expect you will retort that twinning up the numbers is essential in the US due your airspace being busier than anyone elses    (which is the standard reply from our US members), but we have our own busy airspace here in the UK yet we can still manage to address all the dots on the screen correctly using their full callsign and correct phraseology without any of them crashing into each other and people dying. The slack way of doing things in the US comes down to one thing : laziness.

From what I have heard the UK ATC is one of the best in the world given high traffic volumes and still managing to keep things calm and in perfect order. European traffic volumes are very high by all standards so there is no need for excuses. UK ATC clearly shows that even native english speaking controllers can communicate with asian crews without constantly creating confusion by talking fast with local accents.

In this pilot's defense, he seems to understand just fine and gets a little better.

This Air China guy is the worst I have heard so far. The Air China pilots we hear here at ARN are far better than this. This freighter guy should have stayed in China!!

You should listen to the Pacific oceanic comms some time! This sort of thing is quite a regular occurence with the Chinese and Korean airlines.

No wonder this debate is going on. What I thought was bad ATC english before comes in another perspective when I hear this... I doubt ATC here would put up with such low standards. And they send this to Chicago!! One of the busiest airports in the world!! Simply amazing... When hearing this I think Chicago ATC is doing a great job continuing talking to this guy in the calm way they do here. Very professional ATC. But after hearing this I would not be surprised if ATC sent a report. Or maybe they are told to avoid sending such reports for diplomatic reason?

@Navigator: Absolutely, the british ATC is very professional. They always work in a very silent and serene way, compared to the extreme dense traffic situation, they are the best in the world.

To take off without a proper clearance is fully incomprehensible!!
Since the disaster of Tenerife in 1977, the wording is clarified and the term "take of" is only used as part of the take off clearance, for nothing else. (For example: "xxxxx line up and wait...number two for DEPARTURE).
So all line up clearances, hold short clearances or delay clerances will never include the term "take off".

Furthermore every pilot should have that common sense of good airmanship to confirm everyhting which is in doubt, especially in that cirtical situation.

In my opinion there are numerous countries which pilots do not have that language professionalism they should have, I listen to that every day.

Nope.... normal take-off performance prior to V2 should still allow to abort within the confines of the runway

Umm. No. V2 is takeoff safety speed. The speed typically flown in the event a one engine inoperative situation occurs.

You were thinking V1, the aircraft must be able to stop on the remaining runway prior to and including V1.

Oops, fat fingers....again. Sorry

Quoting Gonzalo (Thread starter):
confusing a Line Up and wait clearance with a take off clearance, I can understand


How can one be confused with the other...given differences in language cultures is not an excuse to misconstrue an ATC's command to NOT take off. "You are cleared for take off" are probably the most important words a pilot from any country should understand, other than "Pan,Pan,Pan or "We are declaring an Emergency" or "Captain!,...we are out of coffee!"...... An why they (FAA) did away with "Position and hold" is just nonsense. When I have heard China Eastern over the JFK frequencies they (pilots) are very difficult to understand and JFK tower has to demonstrate extra patience with them as the A346 does not move easily around JFK. Patience has not always been the case...

Even if it may sound like crap it is ATC controllers job to always be patient and very very clear in their communication. If they get stressed by these chinese guys I think they should not be controllers at all. That said I think China should do more in educating their pilots in the english language. There must be ways to improve the standard.
