Hi Ed.

When you save the flight plans, you get a choice of how to save them. Mine are normally set for FSC and FSX. So if there is a check mark (tick) in the boxes for FSC and FSX then it will be saved to both and the FSX flight plan will be in FSX format. Save it as something like DEP-ARR-FSC (e.g. YMML-YSSY-FSC) so you know it's the FSC plan you created.

Once you have your flight plan saved, start FSX, then, using Free Flight, start at the departure airport with the 707. Now open FS Flight Planner from the menu and load the plan you saved with FSC. Now you are ready to fly the flight plan. Go back to FSC and connect to FSX and fly the plan, only using the 707 autopilot (Autopilot Mode Selector knob set to NAV). FSC will follow the flight, but you will be using the 707 A/P, you will hear when you reach each waypoint as it will give you that "bingggg" sound. ;D

Hope this helps.
