EVA Air (BR) #15 ? 15-Dec-2016 ? KLAX - TPE / RCTP ? FlightAware

The EGWPS would have been screaming OBSTACLE, OBSTACLE PULL UP! and/or TERRAIN, TERRAIN PULL UP! with some hard to ignore visual cues on the PFD on the planes I've flown. I realize there are many modes, revisions and database options but I can't see how any EGWPS in a Triple would not see those hills rapidly rising.

I imagine that was happening. It seemed the voice of the EVA pilot got more serious as the mountains became closer, presuming the ATC youtube recording above has properly sync'd the flight path and the voice recording.

FWIW I found a pic of the Mt Wilson Antenna Farm as of 2001 and even then it was pretty impressive:

From then on, despite repeated instructions by ATC, EVA015 does virtually the opposite of what is asked, bringing it into conflict with Air Canada 788. This takes up valuable time while the controller tries to resolve that problem. The EVA015 radio pilot sounds more and more stressed and you can hear someone else in the cockpit shouting at him.

I don't think I'd go with "entire", but would say this thread seems to be fixated on radio terminology (which I can say is a pet peeve of this forum after reading it for more than a few years) and largely ignoring the fact that the crew was told to get to heading 180, and acknowledged that, and regardless of the issue regarding left turn vs right turn, flew heading 0.

For a flight tracking project, I've learned how to position a camera point of view very precisely in the 3D virtual globe of Google Maps. Using the BR15 ADS-B data on FR24, I can put a camera (or cockpit) position in the Google virtual reality and simulate a cockpit view (yes, simulating! Neglecting bank angle, time of day and weather, of course).

One data point before closest approach to Mt. Wilson would look like this:
https://www.google.de/maps/@34.21431.../data=!3m1!1e3,
using the position from the FR24 KML file, an interpolated track(turning!) of 67° (mean value between 59° and 75°) and an altitude AGL of 666 meters (FR 24 calibrated altitude 5625ft (1714m) minus Google Ground Elev of 1048 meters))

Thanks for this link and the others, they were really informative. The view out the cockpit reminded me of ones from my Pilatus B-4 glider, and not the ones I'd like to see when departing from LA on large commercial transport!

There are a lot of pilots that shouldnt be flying in the US!

The Mt. Wilson antenna farm hasn't probably changed much since that photo was taken. The really tall antenna is in the far distance and hardly shows in that photo.

If you cared to read through my posts carefully then you would realise I have said my operator is approved, not self approved, but approved by the FAA. Written in our manuals.

We operate fuel critical long range sectors out of the west coast, often at times with reduced reserves and every kg of fuel counts.
I operate similar sectors, but nowhere in our manuals does it say we can accelerate to high-altitude climb speed once clear of the coast. What are the exact words in those manuals, and which manuals are they?

Haven't flown EVA for about three years but up until then did so fairly often. The pilot was often an American or Australian, so are you sure of the nationality of the flight crew on this occasion?

cappt 22nd Dec 2016 21:54

I wonder how the autopilot plays into this. I imagine the reluctance to click it off and roll the A/C to heading 180 could have resulted in the delay in turning. We all know how slow auto can be when you need him to do it "now".
Hence the hand flown break-out requirement on PRM approaches.

Even if the crew was indecisive over left or right to 180 and went straight ahead for a while they should have had plenty of EGPWS warning of the hills. In the sim it's hard to get a surprise warning since the hills pop up on the screen and you get close to a minute of notice through visual and aural cues before the PULL UP call.

There are modes and sub-modes and different Mark numbers of the EGPWS systems but I believe every 777 has it installed. But, I may be wrong. Remember years ago after a CFIT when it turned out that Air Inter didn't have GPWS in its A320's since it wasn't required for domestic carriers under French rules?

This was really a close one, like United's near CFIT at SFO in 1998:


United pilot inexperienced in landings nearly crashed 747

Saturday, March 20, 1999
By Glen Johnson, The Associated Press

WASHINGTON - A United Airlines jumbo jet that lost power in an engine during takeoff from San Francisco dipped low enough that its thunderous roar set off car alarms and sent airport neighbors scurrying for cover.

The pilot of the Boeing 747 so badly mishandled the recovery last summer that the plane cleared the 1,576-foot-high San Bruno Mountain, a few miles to the north, by only 100 feet, government and airline officials said.

"Pull up! Pull up!" shouted other pilots in the cockpit, as the electronic voice in the plane's ground-proximity device warned: "Terrain! Terrain!"

Long Haul,
Surely any turn instruction issued by a radar controller, (anywhere), should include the direction of the turn as well as the desired heading?
It's basic stuff, really.

Looking at the radar plot, it looks very much as though they turned left and headed 018 degrees instead of 180 degrees. That mistake and then ignoring ATC is what caused this whole incident.

It's basic stuff, really.
Most people heading 090 on being told to turn left heading 180, would query "confirm left heading 180?", and if ATC did require a left turn onto 180, they would normally say something like "left left heading 180" to indicate it was an unusual direction to turn for that kind of heading change.

However, whatever happened, EVA015 proceded to head 018 degrees and ignored all further orders to turn until it got serious in terms of terrain closure. With the EGPWS going off, and the exasperated controller saying "EVA015, WHAT ARE YOU DOING?" and telling them to turn southbound. the penny finally dropped and EVA015 probably then realised that they were in big trouble and started actually obeying ATC.

flyhigh85 23rd Dec 2016 05:26

I have flown to LAX several times and other major US airports and I totally agree with you. In very busy airspaces like those they should stick to ICAO phraseology to avoid missunderstandings and unnecessary RT congestions because your respond is "say again". We always mention ATC as a threat going into LAX. It also feels odd when you are number 3 or 4 in the line going in and you are cleared to land!

EstorilM 23rd Dec 2016 05:51

Forgive me if I missed it, since I'm on my phone.

I feel like I've heard terrain mentioned on ATC transcripts before?

Such as "EVA015 expedite right turn, heading 270 for terrain clearance" or something like that? I obviously have essentially nadda comms experience, but I feel like I've heard that on accident tapes or general ATC recordings.

AerocatS2A 23rd Dec 2016 07:22

I heard a a heavy out of Melbourne being told "Expedite climb, terrain!" by ATC. So, yeah it happens.

Sounds like someone who hasn't flown much in the US and simply isn't used to American ATC. I am not native but flew in the US for over 3 years. Once you get the hang of it their ATC is superiorly efficient, imho. However, like driving in the UK, there may be little room for the ones that underperform. Like EVA showed in this case. It's all about what you are used to...
I think it's much better to get cleared to land further out without the stress of hanging on the stall warner (not literally) going into LHR, coz you can expect big bollocking if your wheels are to touch the ground before.

lilflyboy262...2 23rd Dec 2016 11:53

172_Driver, Therein lies the problem. "Once you get the hang of their ATC"

A lot of the long haul drivers do not regularly fly to the USA. Being in South East Asia, it is a very real possibility that you only head there a few times a year.
It could also be that they have never been there before. Combine that with a fatigued or underperforming crew member and you have the potential for a big problem.
Standard ICAO phraseology, while maybe a bit more cumbersome than the USA phraseology, will avoid these issues.

Out Of Trim 23rd Dec 2016 11:56

I agree with ATC Watcher...

Uplinker, they were turned left onto heading 180, which is the the long way round via a Northerly track.. Little wonder they got confused. Very poor ATC in my opinion!

Dorf 23rd Dec 2016 12:53

They ignored the first call to turn left to 270, which they read back. No SA.

The controller was definitely sloppy and should have been handling these guys very carefully as SoCal usually does with the marginal english speakers.

The controller shares a good but of the blame, but if the pilots were competent this wouldn't have happened.

Snakecharma 23rd Dec 2016 14:04

Dorf I am not so sure.

She gave them a left turn the long way around to start with which she followed up with a string of rapid fire instructions including a range of level instructions. If indeed the initial instruction had the nose swing through a northerly direction in its way to 180 and she changed the direction of turn in a subsequent instruction then the machine is going to head north(ish) as it changes the direction of turn, something not easily discernible from the radar paint - coupled with a lag in the radar display vs the actual aeroplane and there is scope for a disconnect.

These guys do not have English as a first language and given her voice got higher and louder with each instruction they would be sitting there go "wtf" in their native tongue trying to figure out what the hell she wanted them to do.

If the aeroplane was turning left and then she countermanded the instruction with a right turn then getting a heavy fast jet (I.E. A heavy jet going fast, not a fighter for the pedants) to change direction isn't a snap roll type of thing and if you then add in the possibility (though I thought you would hear it in the background of their radio transmissions) the egpws going ape**** then there is the recipe for a cockup. There is the added question of whether in the 777 the autopilot always goes the shortest way to a heading or whether it goes in the direction the heading knob is turned. I don't know but it wouldn't surprise me if it takes the shortest turn to the selected heading, so to do a long way around turn you have to turn the heading knob slowly(ish) to get nose to within 180 degrees of the assigned heading before dialling in the assigned heading. Throw in some rapid fire instruction and directions of turn with the oddball "southbound" instruction and there is even more complication.

All in all the start of the problem was the first instruction and it unravelled from there.

I have flown in and through most continents and I find the us Atc to be challenging at times because of the rapid fire instructions that are not necessarily standard phraseology. South America is the worst because I can't for the life of me understand the accents at times, Russia is surprisingly good, though for some reason they always sound like they have a bucket over their heads.

I agree SA is important but whether it was the time and place to start the discussion about the direction of turn when they got the initial instruction is debatable, particularly from a cultural and language interpretation perspective.

In some other jurisdictions the **** would have started hitting the fan and not long afterwards a different voice would have come on frequency as the initial controller got stood down.

crablab 23rd Dec 2016 14:25

Although her instructions weren't great, I believe the English proficiency of some foreign pilots has a lot to be desired. I don't think they understood that they were being asked to do, otherwise why would you continue to fly into some mountains instead of turning southbound!?

Interesting that Eva were given a right turn onto 180 which they completely ignored - hence they ended up going into the mountains.

KelvinD 23rd Dec 2016 14:36

I take it you can show this? The FAA report says differently.
Snakecharma: Spot on. Once you have started turning left (regardless of the nonsensical order), passing through North is going to be certain.
For me, the mystery remains; why was this flight the only one told, repeatedly, to turn "southbound"? I have no doubt a non-English speaking pilot would understand 180 degrees but the term "southbound" over the air may be a different issue. What we don't hear is the conversation on the flight deck that may, for all we know, gone along the lines of "What the hell is she talking about?" Or "left turn to 180? Well, you heard her, that was what she said".

IcePack 23rd Dec 2016 14:38

ATC watcher. Uplinker only made an observation & speculated what the EVA crew thought ATC had said. Yes I expect they suddenly got situational awareness if their EGPWS suddenly responded to the approaching terrain.
As for poor ATC well the USA is pretty lax but not any way the worst. One controller in another part of the world tx: Xxx for your information I have lots of the aeroplanes coming & going all over the place!

crablab 23rd Dec 2016 14:41

In the initial tx from the controller we do not hear whether she said "left" or "right" heading 180. We only hear EVA acknowledge "left" heading 180. The question remains whether she inadvertantly said "left" or if she did mean left as in all the way around. My own experience is that controllers generally, for clarity, add "the long way around" in their tx when giving such turn instructions. 98% of the time LAX traffic departs on westerlies and indeed turn "left" heading 180. There is an outside chance that in a moment of distraction (a great deal goes on simultaneously on a controller position) she did say "left" by habit. This may have confused the EVA. However, the crew should have immediately sought confirmation.

Ushuaia 23rd Dec 2016 22:30

Snakecharmer: spot on.

The initial "stop your climb" instruction came at a critical time. The controller issued contrary instructions to AC at first ("stop your climb, AC; correction, expedite yiour climb AC") and then to EVA "stop your climb!". All in a raised, urgent tone as if to say: imminent collision. Picture the EVA flightdeck: trying to correct the left/right thing then suddenly it's "STOP CLIMB NOW!" Any pilot knows what happens then: you will get the nose down ceratainly, probably to the brief detriment of getting onto the heading. They'd task shed. They would be briefly rattled; anyone would be. And THEN it was turn "left onto 29, correction, 270", towards the AC who they are thinking potential conflict with. "WTF?" they think. Pause. Then "what are you doing, turn southbound now". The shortest way being at that point..... a right turn now. No wonder these guys came back with "left..right..?" at one point.

Very confusing controlling. I have flown into LAX and other US airports a lot and this sort of stuff doesn't surprise me at all. Most of the Yank controllers are excellent; they have to be. But a significant number are too culturally insensitve, lack understanding of what goes on in a flight deck and seem to forget we're all on the same team. Trouble is, half the people's attitude over there is "if you don't like it or can't hack it, don't come here!"

Poor language skills by EVA, yes, but this is primarily an ATC problem all of their own making.

P.S. Please: every pro pilot knows a turn onto a heading the "wrong way round", is certainly not unusual. Off 06 or 07 in LAX and a left turn onto 180 deserves some extra confirmation, sure, but its not wrong, as such. I have routinely departed LAX from 24L and made LEFT turns initially before heading out to the north, north-east, to Vegas and beyond. Doesn't seem logical but its all about traffic flow. Now these guys read back the initial "left 180", providing the controller a opportunity to correct either her initial, erroneous instruction or EVA's misunderstanding of the turn direction, and she didn't take it. It all started at that point and went downhill with the poor controlling thereafter. Thank God its really only bruised egos....

My own experience is that controllers generally, for clarity, add "the long way around" in their tx when giving such turn instructions.
Thank you for this observation, as a Pilot and the owner/teacher of an English for aviation language school this is good to know, the rest of the message (below isnt't aimed at Hotl Tango... Just some observations..

With my students, in all classes we run a section about RT used in the United States, which is for my students to have a broader knowledge of how the USA breaks from the norms of most of the rest of the world. As a commercial pilot based in Brazil you will find that a lot of your interational flying is done to the USA and, infact ANAC (th Brazilian FAA/CAA or what have ya) have molded there English exam (to some extent) with this in mind. However, I think that it is absolutely fundamental that when my students leave to take their exams that I can sleep at night in the knowledge that they have received more than just enough education to perform, that they understand that infact, ICAO 4 is far from perfect and while I can not cover every eventuality in the time that we have, the student will certainly continue to consider and study the many differences that exist between reality and standard RT in the States. When I have the time, I will start another thread on this... However, ANAC here in Brazil are now actively lobbying and petitioning the USA to improve and starndardize its phraseology to be inline with (most of) the rest of the world.

With regards to the quoted text, I actually just called a student, who is a commercial pilot for a blue airline here in Brazil, a 10k + hours captain, who has just received level 5.... When I asked him to readback and then to explain the message "turn soutbound, the long way around" after explaining that he was currently climbing through 6000 and heading 030...... The read back was a tongue twister, he mumbled long as something between long and wrong - he was also unable to explain in Portuguese exactly what the controller wanted him to do.... Setting him up in the same position and saying... turn left heading 180.... there were no problems at all, both the read back, and his explanation of the situation were perfect.

Bestcontracttill... 24th Dec 2016 01:53

Took off easterly,a bit b4 Eva that day, in not your typical sunny LA weather with winds up to say 7000' being no factor for the climb(in a 74-4 just below max TOM).
Of course a direct track overhead Mount Wilson after t/o was no option, even with a slats extended climb and 250kts.

Having flown a mix off meds and heavies it strikes me how often ATC seems to have no clue of the ac performance, especially in areas like SA(Quito-Bogota, although Quito is getting much better).

Was just wondering how much training our ATC colleague's get in ac performance.

Any ATC lads/ladies who can enlighten?

framer 24th Dec 2016 05:43

Saying " the long way around" is a classic example of where the US controllers go wrong as evidenced by JumpJumpJump 's story. If you want someone to be confident that the instruction is indeed meant to be 'the long way around' you simply say " turn left, left heading one eight zero".
There is so much extra jargon and unnecessary words used in the transmissions that it is no wonder the frequencies are often more congested than they otherwise would be.
I'm not excusing the Eva crew but the ATC was atrocious.

Ha ha ha, ATC Watcher; that is priceless ! My comments in this thread refer to the ATC recording on the youtube link given in the first post, which I have listened to about 5 times. Perhaps I have missed something?

For what it is worth, I have 16 years commercial passenger flying experience, including 10 years flying heavy twin jets (A330) longhaul across the Atlantic to the USA, Canada, and the Caribbean. I have spent thousands of hours listening to and responding to ATC instructions, including some truly atrocious ATC in the Middle East, India and SE Asia.

The incident on this tape has some mistakes from both sides, but the first one and the majority of the others are made by EVA015. We don't hear whether ATC said 'left' in her original instruction, but that is immaterial. Given 180 degrees from a heading of 090 one would query a plain "left" instruction. But they did not query it and neither did they turn onto 180 degrees - they turned north (I reckon onto 018 degrees) !!

This put them into conflict with the Air Canada 788, who was minding his own business, following the GABRE SID, and the controller then had to rapidly prevent an airprox, by stopping the EVA015 from climbing, and telling AC788 to expedite their climb to 12,000'.

Yes, she starts to sound concerned and trips over herself a couple of times but faced with EVA015 being in completely the wrong place, approaching the AC788 and ignoring all her instructions, who wouldn't? Having got AC788 safely out of the way, she climbs EVA015 as she sees he is heading for Mount Wilson. She is not up to the extremely high standard of UK London TMA controllers, but the instructions she issues sound clear to me, and I would not characterize her performance as "atrocious", far from it.

I did wonder if EVA015 had suffered a compass malfunction, but they do eventually turn onto 180 degrees, so presumably not.

I don't think that at any point the pilots were "ignoring" her instructions. Misunderstanding, misinterpreting or NOT understanding, maybe... but at no point was the controller being ignored.

Atrocious is a strong word, I agree, however.... Both parties were operating within the bounds of their respective licences. The EVA pilot must have at least ICAO level 4, if not his flight plan out of his home country wouldn't have been approved, the controller is also qualified and was operating under the rules and norms of her own country..... And therein we find the problem.

It is largely irrelevant that that clip clips the initial instruction from the controller as the controller had a final chance to spot the left turn was being initiated when the pilot readback "Turn left heading 180". RT communications should be a similar process as establishing who has control control... I have control > you have control > I have control...... in this sense should be.... Pass instruction > Readback > Listen to readback to assure that the readback was correct and that the pilot has understood the message.... or to assure that your first transmission was correct. So depending on the initial message, what we should have had here should have been either...

ATC: turn left heading 180
EVA: Turn left heading 180

or

ATC: turn left heading 180
Eva: turn left heading 180
ATC: Eva, Correction, turn right heading 180
EVA: Turn right heading 180

or

ATC: Turn right heading 180
Eva: Turn left heading 180
ATC: Negative EVA, I say again, turn Right heading 180
ATC: Turn right heading 180

Situation 1, would have led to a situation similar to what happened, but would have been resolved faster with the continued use of standard RT.

Situation 2 would have been a non-event.

Situation 3 would have been a non-event.

What will need to be addressed as an outcome of this event is whether or not the English Language Exam in the pilots state is sufficiently good fr international operations and whether or not US RT is sufficient for foreign pilots operating in the USA. It would also be worth noting the amount of time since the pilots took their English tests and whether or not sufficient time had passed since any language training was given in which the pilots would have suffered a decline in their language skills. However, I am still willing to say that the major factor here was the American system, and that further cross cultural training and a tightening of the US standard RT system MUST be given, whilst I think that this must be rolled out at all stations across the nation, it should DEFINATELY be improved upon at all centers and at all TMAs of international airports. This wasn't necessarily the direct fault of the individuals involved.

Well said. I would also add:-

Eva: Request high speed.
ATC: Negative. Do not exceed 250kts.

A stupid request from EVA whist still tracking away from destination, foolishly granted by ATC. Allowing the A/C to increase speed during a large turn only complicates her task to get the A/C eventually tracking towards its destination.

ATC: EVA, What are you doing?

Even the French "say edding" would have been better!

Always was such a welcome sound - that first contact with Scottish or Shannon control after a trip across the pond.

When I turn aircraft the long way around:" EVA15 it will be a left turn on course today, turn left heading 180". I also only give the non English types one instruction at a time. May take a few extra transmissions but you save time not having them asking to confirm something or a long winded reply. With the US not being responsible for errors in read backs, I sometimes wonder if they pay attention or if they are already onto the next task in their mind. And did I hear correctly she assigned an altitude with a frequency change and didn't receive a read back? Seemed like an accident/incident waiting to happen.

All Boeing products afaik turn in the direction closest to the HDG target in AP HDG mode. So to turn left to 180 from 90, you would need to turn the heading bug left to 350ish degrees, wait until close, then continue the knobbing left to 180. But I don't suspect any of us know what AFS lateral mode they were in. Likely HDG mode, but we don't know.

Some observations:

I have watched movements on FR24 prior to this incident. Runway change took place just after midnight (local time), about 1 hr and 15 mins prior to EVA15's departure. During all this time every southerly departure turned right onto 090 followed by a further right turn heading 180. There were no left (all the way around) vectors for any previous departures. Furthermore with the ACA departing off 06R it is incomprehensible that EVA would have been given a deliberate clearance to turn left all the way around as this would have immediately created a conflict with ACA (as it in fact transpired).

So, again it comes down to the unheard (by us) initial tx by the controller. And indeed, as mentioned by Uplinker, the EVA initially turned left and flew on a heading of approximately 018. So, did they hear "left heading 180" and, instead of confirming with ATC, put the emphasis on left and decided "oh she must mean 018"? Who knows?

The official transcript will in time shed more light. What was said on the F/D will also be of interest, but that will probably never be known.

I was thinking maybe the Boeings turned in whatever direction the heading bug went for a turn of more than 180 degrees. In other words, if you start cranking the heading to the left, the plane banks left and will not reverse turn direction if you continue turning the heading knob more than 180 degrees from the current heading.

But, I'm not sure. Some of this detail stuff on the avionics and automation is 'pin selectable' like the single cue or crosshairs flight director. And some of the autoflight behavior is subtly different with with different engine and airframe combinations.

So I do exactly what you describe, walk the heading bug around keeping it less than 180 degrees from the aircraft's passing heading.

I'm trying to think if I've ever had a heading like 018 (other than maintain runway heading) given for vectors in airline flying. If that's what I thought we heard, like everyone here says, I would question and confirm.

Also, is there an ICAO ATC phrase that implies 'turn the long way around'?

FAA Order 7110.65—the ATC handbook—lays out the vectoring toolbox in section 5-6-2. Let’s roll with the basics: “FLY HEADING (degrees).” The controller wants you to turn to the assigned heading, but which direction should you turn? The Pilot/Controller Glossary’s Fly Heading entry says, “The pilot is expected to turn in the shorter direction to the heading unless otherwise instructed by ATC.” If you’re heading 089, and ATC says “Fly heading 270”, you’ll make your turn to the left. If there’s ever any ambiguity—for instance, if you’re flying 090 degrees and ATC wants a 270-degree heading—verify the direction with the controller.

If ATC indeed needs the turn in a certain direction, they’ll employ the second tool: “TURN LEFT/RIGHT HEADING (degrees).” Let’s say you’re heading 089 degrees again and need a westbound turn, but off your left wing there’s an obstacle or traffic. “Turn right heading 270” ensures you make that turn in a safe direction. If the direction is truly critical or the turn direction is counterintuitive, controllers may add extra emphasis, such as, “Turn right—again, turn right—heading 270.”

The phrase "Long way round" is in many aviation phraseology collations.

Photocopiable Glossary of Aviation Terms Word Definition and examples Resolution | Toni Lazarovski - Academia.edu

Normally, repeating 'left' twice is sufficient with emphasis on one of the left's is sufficient: "Left, left, heading 180" -- this avoids the query: "XXX confirm left180?"

Adding 'the long way round' is also common for the same reason and just avoids the potential queries or worse a direct right turn despite saying "left". "Left, left the long way round, heading 180"

I keep hearing in posts here that in the US controllers have no read back responsibilities. That is not true. They are required to monitor and correct a bad readback and face discipline if they miss a bad readback. What is true in the US is that as a pilot if you read back a clearance wrong and the controller fails to catch the error it does not absolve you from possible FAA action.
