Re: Could MD-11's used domestically do without the winglets?

Is there even a CDL for that? I know you can for 330/340, 747 and most others with wingtip devices. But my MD11 work was entirely powerplant, so I am a little curious about that. No. The lower winglet assy can be removed, but the upper or main winglet can not. It's a big job, requiring tank dive an...

Re: Could MD-11's used domestically do without the winglets?

The winglets on an MD11 are a completely different animal than the winglets on a -400.

On the MD, they are structural. On the -400, they are over glorified fairings.
