I’ve programmed the FMC with a quick flight from Belfast to Newcastle. No issues and all weights, speeds, GPS Location etc all set.
FMS#1 is active, yet the Green VOR is showing on the Compass Rose? Should this not change to Nav/GPS magenta line?
Missed this also but finally after checking the expert serie youtube find that you must have nav1 nob to fm1.
Then later on when for example use ils change nav1 nob to v/ils1
Hope that helps
