Engine failure

Okay, just so I know if I should interrupt my flight at 1/5th of my flight done to land in emergency,
Say E3 fails (on a 747 so 4 Engines) should I just shut off E2 to stabilize the push and keep going, or just land?

Because on my last flight, E3 fell on-route, I decided to shut off E2 to stabilize the push and I turned around for the nearest airport I knew large enough to welcome me (KJFK, at about 60 miles behind)
Would it have been wise to keep going all the way to KMIA with 2 engines down (I know E4 would most likely overheat to keep a push equal to E1 and E2, or wouldve ran out of fuel so I justs shut off E2)?
 
Hi Pierre-Nicolas,

As I know, engine failure is an emergency case.
Even if you aircraft is certified ETOPS like all 4 engines and most of twin, in case of engine stop, you must divert to the nearest airport with aircraft facilities.

Hope this help

Cheers
Pierre ;)
 
This pretty much answer my questions
Was wondering when I'd have a failure, done 19 long flights (3h+) with 0 failures :( I was due for one eventhough KJFK was really foggy with crosswinds :p
too bad my flight didnt last just a few more minutes, im 1 point away from a new Air-Child pilot rank :(

Thanks for the help
Pierre ;)
 
Good decission to divert but I would not shut down engine number 2. The Yaw should not be a problem and when it is you can always reduce power on the engines 1 and 2. If you shut it down you loose perfectly good power that you might need for a go around or to maintain altitude to cruise to your new destination.
Just shutdown the affected engine and divert.
And 1 small correction, couldn't resist it :oops: ETOPS stands for Extended-range Twin-engine Operational Performance Standards. It is only for twin engined aircraft, not 3 or 4 engines. ;)
 
In case of an engine failure you might have to descend to the maximum FL possible using only one or in your case 3 engines (Check your FMS for that information). Terrain starts to be an issue when experiencing an engine failure, that's why flying over mountaineous terrain needs special flight planning (e.g. crossing the andes, crossing the alpes with let say DHC-8).

Don't shut engine Nr.2 off, you'll need the power. One major factor in the decision where to divert would be the current position and the airports suitable around you and the maintenance facilities available at those aerodromes (are you familiar with the procedures; e.g. company aerodrome). It depends all on the "kind" of engine failure. The engine might be burning or you might just have unusual vibrations, many things to consider while deciding what to do next and where to fly to...

In my case, the failure was due to E3 oil temperature raising too much resulting in a slight performance lost, but, since uncorrected, complete engine failure, I didn't notice the difference as I was talking to a friend at the time of my flight :oops:

And I shut off E2 because because I knew I was just by the ocean with absolutely no dangerous terrain around and a clean landing for my airport (had to GA, ATC wanted me to land within 15 miles when I was at 11,000 ¬¬) I wouldve landed manually, but due to heavy fog the airport was IFR (and I didn't have a single visual on the airpot until 2 nm from it) and with 2 engines on one side and 1 on the other, landing manually would be somewhat hard with a stronger push on a side and weaker on the other (I use the default 747 I have PMDG but its a frameratekiller or just makes my laptop overheat and shutoff in flight)
 
Still, don't shut it off if it's still running :rofl: But I see that it might be a problem with freeware addons aircrafts.

Hy,

I have to underline my previous writers. Do not shut down a working engine. It`s Murphys law: If something can go wrong e.g. not enough thrust, it will go wrong :devil: .

So accept the asymmetrical thrust. You can train it if you want. Put one engine in idle and don't touch it anymore. Unless you have a real emergency.

But don't take this critique too hard. Because every landing you can walk away from is a good one ! :hi:
So just try something out!

See ya in the air

Ahh well of course I shouldve put it idle :p but then it wouldve moved along with the other ones as I use a pretty basic joystick for flights...but I knew with only 2 engines running thrusts could be a problem so I made sure to keep my speed 50 kts above stall speed at all times, and 30 above when on short approach :p though to add up to the fog, I had intense crosswinds so my landing was not all so straight but I managed to lland correctly :p ill keep my eyes on my oil temperature next time :oops: and idle engines that ruins the push instead of shutting them down, E1 might of died too then id look like a fool with only E4 running ;)
 
with 2 engines on 1 side and 1 on the other, using them all would generate a very unstable push, and I dont think that while flying on my own id have the time to keep everything steady for passengers and set E2's power to stabilize it all :p

True for most freeware addons ;)
