I would love to have the ISG1 Smiths FMC in the 707 so i can fly flight plans anyone know how to do that?

The 707 can fly GPS flight plans made using the FS Flight Planner, or plans made by Third Party addons that can save them in the FS PLN format (like FS Commander v9.2 which I sometime do).

I haven't done an FS Flight Plan (GPS) flight plan in ages. This is how I think I do it (*I'll check later). You load the flight plan from the FS Flight Planner and by putting the Autopilot Mode Selector knob on NAV Mode (make sure that the Doppler/INS switch is set to Doppler, but the Doppler is turned OFF). The only things you need to do is control the 707's speed using the throttles and calculate your own T/D.

I mostly use either the Doppler Navigation or CIVA-INS Navigation (my preference being the INS).
