Aviator: a narrow-body FO here is going to Flt. Eng tng. very soon on the generic 747-200. (then moving to Honolulu!). Are the elec, fuel etc systems the same on the -400, with the main differences (aside from FMC, LNAV, VNAV...) consisting of more automatic relays due to the lack of the Flt. Eng.? Thanks. Our -400 FOs go to the simulator each six months to maintain landing currency, by the way. Very little hand flying the real airplane unless you are one of the two Captains...
