I'd like to take assistance in cracking the error i get when i run the Flightgear simulation via. Matlab. 

The program is written in such way that the airplane for example, the running time should be 500 seconds, airplane must be at 30000 ft height, 120 deg heading, Mach 0.50, KSFO airport (12L runway), etc,. That is the simulation must start with the airplane being mid-air at mentioned speed. 

After running the MATLAB program successfully and the opening of FlightGear tool in MATLAB, the FlightGear opens up and the airplane remains static and is not moving at any direction. I also get the error which i cannot able to recognize and rectify. Kindly visit the url. (I've taken a snapshot of the error box)
