Is there any way i can use a latitude longitude location as a start point for a flight? If i can't do it in FS is there a way of making a designated spot an "airport" so fs will allow me to start there?Many thanks

Move your aircraft where you want it (you can use the map to enter the position). Then save the flight with the ";" (the semi-colon) and set that flight as the default.
