If I enter only the departure gate/ramp in the MSFS World Map planner and launch the flight, then use the plane's Simbrief import routine via the FMC after importing via the EFT, MSFS ATC never gives me the option to use the IFR route in the FMC but instead forces me to announce a taxi to takeoff straight out or directional, then at the threshold gives me the option to REQUEST TO CLEARANCE VFR FROM TOWER.

The other planes I use give me the option of an IFR flight in the FMC and only the PMDG doesn't.  I can use the World Map planner and input an IFR plan there and ATC works correctly.  Any ideas if there is anything else I can do to make ATC offer the IFR option when launching only to a gate w/o a full flight plan from the WM planner?

I think you have to make an IFR flight plan on the world map for ATC to function.

Thanks, but it appears you missed teh distinction.  The WT 787X and FBW 320nx both offer up the IFR option (reads the one in the FMC) and only PMDG 738 doesn't and ATC will direct those flights as it would if the plan was created in the WM planner.

I guess this is because they (787 and A320N) are basically modified DEFAULT planes? Not sure if it works for Fenix and other complex, full addon planes. Is there any addon which is not based on a default plane where this works? If yes, it might be worth asking this dev how he achieved it.
