  • DC-10/MD-10 question.

    I was wondering about the MD-10 (DC-10 with an MD-11 cockpit) and how they got rid of the need for a flight engineer. I know the older DC-10's at least had a flight engineer, but the MD-11 doesn't. How did they get rid of this need? Even with the newer avionics of the MD-11 cockpit, the systems on the plane would stay the same wouldn't they?
    I've also wondered what was done to the DC-10's to prevent another accident like UA 232. I know the MD-11 has the thing called the Sioux City valve, which stops the hydraulic lines from leaking. I know something on them had to have been modified, because I would doubt DC-10 operators would be relying on luck to keep another hydraulic failure from happeneing.

    Computers. Instead of having that huge engineers panel, the 2 pilots can access all the systems via a multi function display. I would also imagine that many of the systems kinda run themselves to a point, granted I dont know any specifics about the MD-11

      ^^I remember when they showed a 747 program at Discovery.

      Here you are in the cockpit, and the narrator and artist in the cockpit, showed how many buttons they saved in favor for these computers, thus also saving the flight enginner's work. Now I dont recall how many buttons it was but , kinda lot if you think at the flight engineers panel, how many of it was transferred to the front panel and the above panel.

        Ok yeah that makes sense. That might have been a dumb question lol.

          I wont say there's no such thing as a dumb question, cause there is. But this wasn't one.

            I have always thought about this Question as well, Jordan.

            But I just never got the guts to state the question here.

            I had always wondered what made the difference between this MD10 and the MD11. Not only visual change on the plane but the designation type, the cockpit-upgrade, as well. Like Emu said, I didnt think this was a dumb one.

              The M11's had hydraulic fuses, other than that, IIRC, the design was essentially the same.
