If I try to Intercept the FMC course I am then vectored away from it again?? Although I may fly a very similar course it renders the FMC useless!!! So can I not use FMC and ATC at the same time??MY RESPONSE:I had the EXACT same problem as I also used FS Navigator to to create my flightplans.

I usually create an IFR flightplan using high altitude airways. I let FS create the flightplan, and then I take note of all the VORs and INTERSECTIONS. Then, I manually enter the route generated by FS into the FMC, and voil
