How to tell the difference?

Apart from the winglets the tail is not as high on the MD11

Not as fat? Well, they do have the same fuselage cross section, and yes, the MD-11 is in fact longer than the DC-10. The winglets are very visible, and to anyone who has X-Ray vision a la superman, can peek inside the flight deck to see the 3rd crew member. For those of us that have normal vision, that’s a little impossible. So no, I won’t be looking for the 3rd crew member any time soon in order to distinguish between the 2.

Thats the easiest way to tell them apart, by the winglets, but to me, the MD-11 looks longer in the front section and not as Fat as the DC-10?

MD-11, has winglets:

DC-10…. no winglets:

hehe matthew

good point now that i look at pictures of them both i can see thanks a330:)

Most basic difference is that the MD-11 has Winglets and the DC-10 doesn’t.
