Firstly I apologize but I have read about every post on FMC/NAVDATA issue and I cannot seem to resolve my problem which is:

Issue: I continually get the  "NOT IN DATABASE" message on the FMC's of both my B777 & B747 but NOT my B737NG when I try to enter the initial airport IAOC Code from the airport from which I intend to fly.

System: Windows 10,  P3Dv4.Active Sky P3D. Orbix multi scenery. FS Tramp. PFPX, Navigraph Data Manager. No other add-ons or weird stuff all up to date. All system drivers up to date.

Troubleshooting: 1.Clean re-install of PMDG B737.747/777. Navgraph.

                              2. Repair of P3Dv4

                              3. Navigraph  AIRAC path re scanned "PMDG ALL Products to P3Dv4 default in Navigraph"

                              4. Tried to manually install AIRAC in to PMDG NAVDATA folder in P3Dv4.

Please Help!!

Many Thanks Marc Biggins
