"Working overhead panel?" But the 767 has that, too.
The functionality of all it's switches also is linked realistically.
But I do not know the PMDG-737. I knew the Dreamfleet-737 in FS7/8, and do own the 747 by PMDG. But I never fly it. somehow, my karma always leads me back to the 767 PIC, when airliners are talked of.
The packlage (767) also came with one hour of cockpit video, describing dark&cold, over in-flight, to landing and taxing to parking. Cool. I recognized and understood all what I saw!
