I just discovered that we can change the standard transition altitude to whatever we want. So, I changed it for Europe to 6000 instead of the default 3500 and tested it and it worked.

 

I just thought I would share it with you guys in case some of you didn't know.

 

Cheers

And how you do that?

go to C:\Users\user\AppData\Roaming\Internal Workings\VoxATC X

 

look for VAsettings. open it with notepad and look for (TransitionAltitude Value="3500") amd change 3500 to whatever altitude you want.
