- Both airplanes are derivatives, actually. The MD-11 was certified under
- the DC-10's certification basis.

- I can't speak to exactly how much of the 747-400's wing design could be
- considered 'new', but I do know that it was modified extensively to
- change the pressure distribution across the wing - particularly the
- inboard wing where we were seeing double shocks on the older models.

- The Fokker 100's flight deck is much more Boeing-esk than Airbus-ish.
- There are control columns, and the FMS is very similar to the Boeing
- models. The F 100 does have envelope protection, as do the Airbus
- airplanes, but I don't think you would find it much different from
- what is already flying. It is a very advanced flight deck, very
- clean.

- Could it be the Performance Management System, a la Douglas MD-80? :-)

-
- You are quite right, three-crew cockpits are union requirements on some
- airlines. The flight engineer on a 767 would do the same job done
- on other three-crew airplanes - deal with onboard systems. All those
- nifty controller boxes are left behind in Seattle. :-)
