With an of the MD-11/-10 family a two-engine out approach is significantly different than just one engine out. It's a slats only approach, airspeeds are significantly higher, no auto-throttles during landing and no go-around option once the gear is down or the aircraft is below 1000' AGL.
Single engine out is a non-event in comparison. Normal flap settings and speeds and auto-land is even an option.
One out of two= I was referring to a twin engine aircraft with one engine out.
The other comments in my post were referring to a three engined aircraft with one engine out ("one out of three").
Maybe you thought I meant one out of three was running? I could see that perhaps. And yes, that would be a pretty big deal. I was trying to say that a one-engine inop in something like a 75 or 76 would be a much bigger deal than having just one engine fail in an MD 11.
You're stating my exact point, with one engine out, it's not much of an event. It's significant, but not a significant change in how you fly.
