DC-10 MD-11 question

Thu Mar 04, 1999 12:39 pm

Could the dc-10 or the md-11 fly with only the 2 WING engines on and the back one [number 2??] turned off? And could it fly with only the back one on?

Yes, The MD11 could easily stay in the air with only two of its engines operating regardless of which two were left on. I have no idea how long if the MD11 would be able to stay in the air on only one engine but I would guess not since that would put it on 1/3 of its full power, it does not matter which since each produces the same amount of thrust.

The DC10 MD11 can operate with any two engines shut down. It would not by any means be able to continue on with a norman flight however. There are many variables that would affect the performance of the aircraft such as payload and it's distribution. the loss of any one engine is considered an emergency. The loss of two would critically effect the way the aircraft handled especially if it results in assymetrical thrust. I am not sure but I would believe that there is no procedure for a single engine go around at any weight. So you had better get it right.

With the two wing engines still on, I think it could still fly because the aircraft would still have two thirds of the power and there would be no assymetric thrust. With only the back engine on, the pilots would have to declare an emergency and land right away. Now the other problem is when the hydraulic lines get severely damaged because of the n°2 engine on fire. That is exactly what happened at United 232 ten years ago, a DC-10 bound from Denver to Chicago that ended up making a forced landing in Sioux City.
