listening to the live atc feed of the accident , I'm getting a little confused if the go around was initiated by the ATC ( recording not very clear ) but the pilot response of climb 4000Ft is very clear . which is pretty much the last conversation , and then after about 10sec you hear a voice saying " did you see that " so that would have been the time of the impact .

And it also wouldn't be the first time a go around has been initiated without pressing the TOGA switches, especially by ex-Airbus pilots, although I'm not saying that's the case here. I've seen it happen several times in the simulator: pilot pushes up thrust levers to commence a go around (without pressing TOGA), calls for Flaps 20, positive climb, gear up, meanwhile pilot takes hands off thrust levers and the thrust comes back to idle. Oops... |
Would be interesting to know what EK's B777 legal temperature operating limitations are as 120f is the normal limitation for most Boeing aircraft. DXB METAR temp as reported was 49c or 120.2f. . . Such limits however, can vary by airline in that they may be extended by Boeing if the airline is willing to pay extra $$ for special engineering (extrapolation) data.
In the USA, many Boeing operators cannot legally operate at temps of 120f or higher. EK I would expect, is in possession of higher limits. |
or even better on the NG,
Goaround, flaps 15, check thrust This is what I am doing This is what I need This is what I want you to check |
So one side of the aircraft is smoking with the engine visible on top of the wing and on the left side no flames or smoke but three perfectly good doors can't be used because the slides were flapping in the wind or blown up against the open door.
With a fire truck and firemen on the ground powerless to speed up the evacuation. Can't we do better? Mickjoebill |
Re: 49 degrees oat. Does it still happen that the actual temerature is above 50 degrees, but the official temperature is kept at 49? There seems to be a local law, stating that on days with 50+ degrees, all manual labor is halted. So they warp reality and officially keep it at 49.
Of course engines at go-around thrust don't listen to this artificial temp. They perform according to actual ambient conditions. |

@sitigeltfel #305 above
Does that flap still look to be set at 30? |
XEQUE--- yes I also look at the Flap position and question it.....doesn't look to be 30, hard to tell?
|
Xeque: @sitigeltfel #305 above Does that flap still look to be set at 30? The following video shows a 777-300ER with Flap 20 at 8:01: https://youtu.be/Xtwne9UbH8o?t=481 Flap 30 at 8:45: https://youtu.be/Xtwne9UbH8o?t=525 Of course the Emirates aircraft could have been using Flap 25 for landing, given the conditions. |

Even with what little is known at present, the circumstances of this event would appear to be quite different to those of the SQ incident, most obviously starting with an uncontrolled 'crash' landing and detachment of the starboard engine. |
MickJoeBill,
further to your comments about evacuation slides being blown around and rendered useless thereby, a similar issue came to my attention with the Korean Air incident at Haneda back on May 27th. (see http://www.pprune.org/rumours-news/5...-2708-hnd.html) If (as I believe is recommended in an engine fire scenario) the aircraft is positioned with the wind blowing the fire and smoke away from the fuselage, rather than towards it, this might create a problem with the slides on the 'safe' side. I don't know if there is an answer to this problem. |
As most on here will know - On a go around, particularly one initiated at a low level, if you don't pitch up at the same time as you apply the thrust then you just accelerate towards the ground at a frightening rate - I've seen it in the sim many times.
I have also seen, sitting at the holding point with a sub 200 foot cloud base, a 747 exit the overcast apparently still on the glideslope with the wheels in transit and very nearly impact the ground as it climbs back into the overcast. LOW GA + THRUST BEFORE PITCH + TAILWIND COMPONENT/HIGH ROD + AMBIENT CONDITIONS ? Just a thought |
A TWA TriStar was burned out on the ramp at Boston on 19th April 1974, presumably the incident the OP was referring to. |
A CATHAY L1011 EVAC in Tokyo Haneda a long time ago suffered the same problem of the slides blowing in the wind rendering them useless.....
|
Heard that all the crew of EK521 is put up in a hotel so that they cannot talk to media or any one else.
Is this true....??????? |
UK news have several interviews from passengers who all speak very good English and all confirm that there was no cabin call pre-warning them before crashing.

Do we need slides that are better windproofed? In most cases any winds will blow from the nose to the tail so just some minor stabilization (like a rope or some inflatable "anchor" or similar) might make more evacuations slides available?

Things get interesting if you forget to go from F30 to F20 in the Go-Around. F30 Gear down landing rate of climb at 225T at 49 degrees gives you approx minus 190fpm at sea level! Note, all these figures are for SINGLE ENGINE. Performance with both engines even at 49 degrees is not an issue. No airport will tell you you can't land with an emergency. They may 'suggest' other options but, as Captain, it's your choice. Edited to add that these are for the 777-300 GE115. My operator doesn't have the straight 300 so willing to be corrected The radio call from tower for the GA, and the reply from the PM, does not mean that the GA was instructed by the tower. The ATC controller was most likely paying attention and rather than wait for the call from EK521, he was proactive and eliminated a 3rd transmission on tower's freq. The call to tell tower about a GA is pretty low on my priority list, especially in close proximity to the runway. While quiet, you can hear the CA command the evac in the evac video. Sounded SOP to me. |
Just been reported on Australian TV news that the Australian copilot of the aircraft is a Qantas employee and is currently on leave without pay. That makes no sense as Qantas has no 777's. Has to be a misreport.
|
Nope perfectly possible, quite a few surplus QF crew went on LWOP and joined many different Airlines. Some had never flown the type they were employed on and were therefore trained. Most will come back to QF, some won't.
Simple. Oh and it is a standard call for Military Towers in Australia to say "clear to land check wheels" the reply is "three greens" ( or whatever the type has!! ) |
Rumor around at Costa is that it was wake of the preceding AC combined with winds
|
ACMS : Yes. And if the resultant prang & slide was not anticipated by the crew, everyone did a mighty fine job of handling, instantly, the evacuation. Total praise for that last bit and all, but one, survived. Now, lining up the holes and the blame game will be noteworthy.
|
Slides - IIRC there was a good discussion about the issues way back when they introduced the 747 and Tripp of PanAm was worried about how people would get off
If you make them very stiff they are heavy (bad for economics) and can be dangerous to both the passengers, the fire crews and the airframe. - there is also a problem in fitting and deploying a "hard" slide. And if you want them to double as temporary life rafts................... |

Interesting how little information has been released just over 24 hours after the incident. Who are the investigating authorities ? |
Emirates B777 gear collapse @ DXB?
Re the earlier pics of the flaps. Is it not normal to lower 40 (or more) flap during the evac drill?
|
Not on the 777. There are over wing slides.

Who is investigating?
Is this in Dubai where the temperature never exceeds 50c, the building workers are shipped out each night to camps, a foreigner is automatically guilty in a road accident, you have to pay a bribe to get a drivers licence etc etc? Let's not hope its the locals but I am afraid it will be... |
So, assuming the aircraft was experiencing a significant tailwind, had got high/fast, had the thrust back at idle and decided to do a 'normal' but rather late go-around: how long would it take for the engines to spool up enough to climb once the appropriate buttons/levers had been pressed/pushed?

The point is how quickly a fuselage made of aluminium and surrounded by flammable liquid and an uncontained fire can be reduced to a charred shell, even with Dubai RFF going above and beyond the call of duty. Any doubt, get out. Might it have gone otherwise, and the fire been less easily contained? Yes, in which case presumably the AFS would have communicated this fact to the commander - no doubt continuously re-evaluating his decision not to evacuate - who could've acted accordingly. |
Aussie FO on secondment from QF confirmed.
Australian co-pilot Jeremy Webb escaped Emirates plane crash in Dubai |
The AIB at the state of occurrence will be in charge of the investigation, in this case the GCAA.
Now the AIB is supposed to be impartial but in the UAE it is organized under the governing body of the GCAA - This is in my opinion a problem! In most countries the AIB is completely separated from CAA to make sure that an investigation will be conducted without pressure from the governing authority. Who owns Emirates, who owns the GCAA and who controls the AIB? Lets see how they can spin it! That said Boeing, RR and probably the ATSB will be accredited to the investigation. |
So how will Emirates 'buy' themselves back into ignoring a hull loss as an accident when the safety records are compiled?
In passing I note Gulf news yesterday stated "Emirates suffers first hull loss in three decade history'. And today one of their headlines read "Emirates safety record - Zero deaths in 30 years". |
Emirates B777 gear collapse @ DXB ?
Forwarded to me from a mate who had it forwarded to him :
" My mate is with flydubai and he saw the crash live : Yeah I was crossing runway behind it as it landed ....front row seat ... they landed hard, aborted , go around, gear up ... not enough power and it sank back into the runway .... some are saying windshear but we felt nothing. Crazy site to see ...even crazier that apparently most people survived ! I thought it was a total loss for sure. This was on the fo group chat " The above message was posted as it was received. I can't verify its authenticity and make of it what you will. |
Finger trouble with the TOGA switches?:confused:
|
Sounds plausible. I do wonder if the B777 "landed with equal weight on wheels on each side, whether the spoilers auto-deployed, and whether idle reverse was selected on "touchdown"? And of course whether TOGA was selected promptly? Many unanswered questions.
As for the cabin crew, clearly they performed their job well as a team. |

Well done to the EK crew and RFF. |
