Can't get autopilot to follow GPS

[granman]

Hello,

Nice work on the VC and I'm enjoying your work. The question I have is that after setting up the autopilot, it follows heading properly, but when I click the Nav/GPS lever and turn off HDG, it doesn't follow the GPS flight plan, nor the one in FMC. Am I missing something that you can think of?

Thanks.

I run my own test and pput back the default FSX-737-800 the one exacly that comes in the box ,and it does the same, the Navigation system Glideslope and Localizer (autolanding) stop working on the aproach ,to be honest I never made a "flight plan" in GPS mode, have you try other airplane? about the FMC this is something that does not work even close to a realistic FMC like those in PMDG payware products, its something basic,..

I'll try a small flight tomorrow in GPS mode to see what is wrong there

I ran the test again using the default FSX 737-800 using a gps tracking guide line and then I install my upgraded cockpit....Conclusion :same thing

Do you know how to set up the Flight planer?
1) did you set it to IFR?
2)did you set the switch to GPS?
3)did you set the VOR switch to make the airplane to follow the GPS track line?

Hi Alejandro,

Got it working correctly. Your image helped as I got confused and didn't set VOR LOC. I think in some other aircraft you hit a few different buttons, so I appreciate your help.

Thanks,
