As long the BUG not is repaired you are not able to get the view of NAV/RAD button - in B747-400. (It's functional in B737-800, but not in B747-400)
Only place to set CRS and ILS frequences (especially when map is wrong) is from that FMS window, not able to be visible. Tthe CRS default value is 0 degr. so imagine a landing at RW 19 or 80/260... LoL.
Shame that this bug not have been repaired, I did a bug-report in Januari. Is I alone flying this aircraft and reporting FMS bugs???
Any solution? Or tip?
