Qatar 787 diverts to OTP, engine shut down

[skytrax]

Oslo-Doha
A7-BCT

Landed safely at LROP.
Apparently engine no2 was shut down. Emergency declared.

Edited the error

[ironbutt57]

why the request for turns in a specific direction, is this a 787 thing?

[Momoe]

Turning into the good engine, maybe just being cautious but perhaps control issues?

[olasek]

It is better to avoid turns into a dead engine - on all twin engine airplanes. There were simply too many related accidents.

[TURIN]

Nice little jolly for an engine change. What are the local bars like?

[CDRW]

Olsen - care to share with us some of the many related accidents? And I refer to modern jet aircraft - not a twin commanche or similar.

What a load of rubbish.

[ironbutt57]

only one I recall was the El Al 747 freighter in Amsterdam, but i seem to recall they had lost both engines on one side

[Methersgate]

Do turboprops count? - Breguet Atlantique at Farnborough, 1968?

Lost, as in the number three sheared off and took out the number four along with a load of systems and some leading edge devices, fuel leaks and god knows what else.

Bit different to a 'routine' inflight shutdown.

If I remember correctly GEnX comes in three parts with some assembly required instructions. AI B787 changed a GEnX at BUD. Based on posts from local folks, it was lot of fun with limited facilities.

Turns with one engine inop in either direction are absolutely no issue on the 787...

[sleeper]

Flew all Boeing twins, except 787, and there was never any issue turning over the dead engine. Never noticed any difference including one actual single engine B737.

I see Emirates were changing an engine (RR Trent) on a B773 in Entebbe today. Not sure what the cause was.

Olasek, could you please explain why you hold this opinion? I would say that provided the speed is above the critical speed pertaining for the thrust of the good engine and assuming that the rudder force is trimmed, the flight controls (and any competent pilot) should be capable of rolling into and out of a turn in either direction. I have demonstrated this on numerous occasions during multi-engine asymmetric training.

Furthermore, I don't recall ever having seen this restriction mentioned in any Airplane Flight Manual that I have studied.

I'm not trying to score points: I would genuinely be interested to learn where and when this particular piece of pilot's 'folklore' originated.

Thanks!

The GEnx can be easily broken down into modules - but it doesn't automatically come that way. It's basically dependent on how it's going to be shipped that determines if it'll be shipped as a complete engine or individual modules.

[Hotel Tango]

Doesn't this avoid turning into the dead engine thing not originate from certain somewhat under-powered piston twins from another era, especially when, ehm, heavy?

[JW411]

Yes; it was particularly dodgy in the Vickers Vimy.

Good to know, as twins are getting ever bigger, logistics related to engine mx becoming ever more complicated.

It is most definitely a throwback from the old days when propellor driven aircraft provided extra lift over a wing with the prop wash. For an engine out scenario, turning into a live engine kept the wing that wasn't "blown" by the failed engine propellor on the outside of a turn, at a slightly higher airspeed (more lift) than the into turn wing, reducing the chance of stalling.

Of course this is of virtually no help with an underwing jet.

I don't understand how in this day and age with all the technology available on the flightdeck that you could actually line up on the wrong runway. How hard is it to program a runway extension?

Southwest did it last year now Delta. What are people doing for an arrival brief and setup? Not alot I would suggest.....

I think that the thread that you are looking for is over here.
