The title says enough. I know it’s not possible on cruise level, but at 2000 feet, hmmm must be possible, no?
And another thing. A Russian aircraft crashed because it lost power of nr 3&4. The assymetrical thrust made the aircraft out of control. Is this a pilot error, or are you really in trouble if you get this kind of assymetrical thrust?

How about this situation : –Concorde, Climbing through 10000ft at 300kts, outbound from Heathrow, you lease the 2,3, and 4 Engines. What do you do?
Bend over and kiss your ass goodbye ?

You wouldn’t have any power with which to deploy the flaps so it would be a high speed clean landing/crash. You would certainly have a pitch much much higher than 15 degrees nose down (in fact almost certainly quite nose high).

How do you do that, not too much flaps and a 15° nose down approach?

I’m talking about a 2 engine out situation.

Well, there still isn’t enough info to determine exactly what went wrong there. BUT, Pilots should be able to handle an asymetrical thrust situation be it one or two engines
Perhaps in this Il-18 flight control problems occured due to the loss of power. Perhaps the Il-18 didn’t have backups.
I dunno.

From what I’ve read, the 747 can fly on 1 engine, fully loaded for a short period of time. Enough to get you to an airport.
As for the asymetrical situation, I wouldn’t like to say if the russian incident was pilot error or not. Perhaps the failure of No.3 and 4 caused loss of control systems?
But I do know a pilot should be able to handle this kind of engine failure, assuming all the controls were still operational.
An Evergreen Cargo 742 lost an engine on take off due to heavy turnbulence. The No.2 engine ripped completely off the wing, And took a good portion of the leading edge slats along with it.
The No.1 engine ingested debris and was shutdown.
Although is was a heck of a job, the Captain got the plane back on the ground fine.
Here’s the aircraft in question, safely on the ground.

Although not a four engined aircraft, a TriStar would stabilise at around 4000′ on one engine at fairly heavy weights.
