In the 777, you have to turn on all the pumps and packs on the overhead, whereas in the MD, it does all that for you. It doesn't have a "standby flight plan" and the third MCDU is rarely used for anything, other than Sat Com calls or calling the F/A's in Door mode. It doesn't do "Route Copy" either.

It only has Route 1 and Route 2. We only use Route 2 to load our ETPs and our divert airports. It gets reloaded every time we load a new Route 1, unless we are flying a short domestic leg, like ATL-LAX, where we are not going to load a Route 2 with divert airports.

If you lose both FMS heads you can use the third head for Standby Nav, but it's not going to jump over to Route 2 by itself, you have to activate and execute Route 2.
