Hi everyone-new to the forums so sorry if this has already been asked.
I recently installed iFly's 747-400 package, but I am having trouble with the route settings for a dep/ arr/ airports. I enter the ICAO code of the airport into the corresponding area, but the FMC returns "NOT IN DATABASE". The Company Route function is also not working. Any help would be much appreciated.
