Is there anybody who can advise me. Ihave just changed my operating system from ME to XP-Pro. Now whem loading the DF737 FMC all goes well except that the activated flight plan will not transfer to the cockpit. I can take off but thereafter no LNAV or VNAV available - all looks to be fine in the FMC.Jack

Make sure you're pressing the "EXEC" botton when viewing the Legs page of your route. If you do not do this, neither your laternal information or vertical information will be used by the MCP.Ryan-Flightpro08 :-cool VATSIM Pilot/ControllerZLA ARTCC Senior Controller (C-3)SAN TRACON Lead [link:www.taxiwaysigns.com|Taxiwaysigns.com] Scenery Designer-----------------------------My "Home Made" System Specs:Intel Pentium 4 2.2GHz ProcessorTurbo Gamer ATX Mid-Tower with 420W Power SupplyEPoX 4G4A Motherboard with Intel 845G ChipsetVisiontek XTASY GeForce4 128MB Ti4600 (Det 41.03 Drivers)512MB PC2100 DDR RAM40GB Matrox 7200RPM Hard DriveWindows XP Home Edition SP1*No CPU or GPU Overclocking*3dMark2001SE Score: 11298-----------------------------Click [link:ftp.avsim.com/library/esearch.php?DLID=&Name=&FileName=&Author=Ryan+Fretwell&CatID=Root]Here to Download my New American Eagle POSKY CRJ-200!

Hi Jack,I would suggest you read again the manuals that come with the DF734.Apart from entering the flight plan, you must also provide more information to the FMC before it will actually activate the flight plan and you can use VNAV and LNAV. To give you a hint...Did you enter the ZFW in the Pref page? Did you set up and confirm the Vspeeds? Did you select a departure rwy ?Fly safe,George DorkofikisAthens, Greece

Thanks you where right did not follow the right programming procedure.Jack
