Ok , so it has worked after editing the position and test but when come back to menu and retry it replace the aircraft at wrong position resulting in the same issue.
So for the solution work it needs to entering the editor , validate then it replace the aircraft and everthing is working.
Is there a way for GSX position can be detected immediatly ?
Can you add maybe a feature to repositioning aircraft like the airport .ini file does , maybe Synchronyze airport position with preset ?
To make it work , i need to enter to choose repositionning the aircraft (menu 0) and select GATE C3 , and it is working well then
Thanks
