thanks for good infos… the CTD are new since 1.13.16.0 ? ( it’s realy important info )
I will made a test flight, both airports looks not far away from each other 
PS:. please not write in other threads parallel. It’s a bit confusing, because I sometime think ‘where I have seen this report already ?’ ( examples: 1 , 2 )
EDIT: and is the CTD in your case repeatable ? allways at these route ?
