Hi all,
Uniuniunium.....
Yes, our NGs don't have any lower DU at all, only the 5 screens. This means, of course, that we only have one rotary selector for the DUs, above the PFD/ND.
We do still retain the SYS and ENG selections, shown on the inbd DUs, as we do both primary and secondary engine indications.
...but then again, we do also have a fuel jettison system!
It's an interesting bird, generally speaking.
Another screen replaces the lower DU, for an entirely different purpose.
Cheers, FD
