Hello 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

Thanks. 1, The open crossfeed valves may have been an inadvertent error on my part . I noticed when I closed them on the flight I am conducting now the error has resolved. 2. Yes on downloading en-route weather to FMC. 3. Fuel calculations have been calculated as mentioned and I have landed with plenty of reserve still showing a fuel warning . Oddly this has only just started happening over the last 4 flights. $. Yes I let the FMC calculate my step climbs.

Hi Running PMDG B777 with FSX and fly regularly with a good general knowledge of the sim/aircraft. For some reason I keep getting an "Insufficient Fuel" warning from the FMC. I have had this occur on short and long haul flights. I always carefully calculate loads and fuel and I fly with real weather software. This has never happened before! I have noticed that if I turn off the fuel tank cross-feed switches the warning resolves. This warning occurs prior to departure and continues regardless of my loads and fuel. This is a new occurance that I have never experienced before after many hours in this sim. Any ideas? Thanks Marc Biggins
