When you lose the second engine on the same side, so long as you are just about clean (let's say flap 5 or less, and say 230kts) you should be ok, even at 350+tonnes. Turning towards the live engines requires addditional rudder. If you are lower/slower than this you have BIG problems, and will probably not stay airborne.
