I know its not easy. On the Other Programm i used a Script (on the Flightmaster) in the Dev Tool.
<Objective>UseFlightPath</Objective>
<IgnoreQuestCompleted>true</IgnoreQuestCompleted>
<FlightDestinationX>?</FlightDestinationX>
<FlightDestinationY>?</FlightDestinationY>
<TaxiEntry>?</TaxiEntry>
<WaitMs>?</WaitMs>
With the Script i got the <FlightDestinationX> & <FlightDestinationY> i guess that where the Points of the Flightpaths.
If possible give me a Example that would help me alot.
