No takers? Some of the LCD window features are on Label 147 for the FGMEC's, however when I power the FCU they appear briefly and then revert to the stuff that is being held in the RAM? As if the info is being discarded? And I can't dash the displays, nor illuminate the LOC/ALT/APPR PBs.
If there is anyone out there who knows of this stuff there is considerable beer in it for your learned advice!
