I am having probs with the FMC....when I enter a flightplan from say Perth,(YPPH)-Adelaide,(YPAD) or anywhere else for that matter, the FMC tells me the flight is "not in the data base".I have downloaded the latest airac cycle 08/05 and the FMC shows that as being installed.Where have I gone wrong... I want to be able to put plans in and fly themThanks in advance for any help you can give.Cpt Des
