March 27, 20179 yr Not an issue...mostly the operator but where is the setting to display both FMC's. Somehow or another I got it in single mode. Thanks, Bob M. Bob M
March 27, 20179 yr You have 3 separate MCDUs, any 2 of which can display FMCs, though by default you'll see the FMC options only in L and R MCDU. the center one will only have other modules like PMDG and FS OPTIONS. Of course to have 2 FMC options, you have to have both FMCs online, which means the correct electrical configuration - just the other day, I managed to disconnect the GPU on a 777 before APU came online... and lost the whole right side. Had to wait until the second FMC booted, but eventually it did. --Peter Fabian
