what do these turn knobs do for DU brightness?

Featured Replies

yes, I did scan the manuals but this is difficult since I found no cockpit poster with a reference to all those knobs. so, first I thought I have a bug. brightness of outbound and upper DU was perfectly scalable. But not the one of the inbound and lower DU. until I zoomed really close and realized that the latter 2 have sort of 2 turning knobs in 1 and I need to grab the lower one to adjust the brightness. but what the heck does the upper part do? was turning left and right but could not see a result in the cockpit? in the picture below you see that the lower DU brightness knob seems to be turned completely left = dark but the DU is actually bright. if you look closer you will see that only the upper part of the knob is fully left whereas the base part is fully right and thus the brightness...

I can't remember which is which at the moment, but for the inboard DU knob, one of them controls the DU brightness, and the other one controls the terrain display brightness. Turn on your terrain and turn the knob. On the lower DU, one of the knobs doesn't do anything. smile.png Not sure why it's there, but even in the Boeing manual it says inoperative. Check out page 594 of FOMC 2.
