Hi Folks,
I have discovered a work around for this problem, using GPS1 as the NAV source. Using GPS1 allows the plane to track the GPS course with AP active and NAV mode selected. Here are the steps:
1. Pre-load an FSX flight plan into the GPS while configuring the flight. (As mentioned, I prefer to use SimLauncher 9.3 over FSX's default start up screen, so I load the flight plan through that)
2. When into the powered up cockpit, turn on the FMS
3. Accept the coordinates (if correct, which they should be. A quick <Shift><Z> will show them)
4. Press the RLSK for the X-FILL prompt --> loads the flight plan into the FMS
5. Press the NAV/BRG button on the DCP --> Allows selection of VOR needles
6. Press the Selection Button on the RIGHT bezel of the PFD that displays FMS1 --> This changes the selection to GPS1 as the NAV Source
7. Press the NAV/BRG button on the DCP again, if you wish, to return to the previous screen button selections
8. After takeoff, engage AP, YD, ALT, VS, and NAV - the plane will then track the GPS1 Flight Plan
This may just be a work around, but it DOES work to get the plane to track the flight plan automatically.
(Incidentally, this plane works well in P3D v2.2 I'm LOVING it now!)
Off to start learning the Citation X hope this helps anyone else who may be having the problem I was having!
