I have recently discovered that when I tried to fly from North America to South America, the only place I can go is Brazil. The fs9 CTD when I fly to Argentina Buenos Aires' Ministro Pistarini International Airport or Chile's (SECL) from anywhere. Anybody know what is happening? There is no duplicate AFACD files as I have checked. I have a Buenos Aires and Santiago sencery though. However, I can fly from the respective airports up to a certain distance. For eg I can fly locally from Chile's SECL and go around up to a 120 mile raduis and then fs9 CTD. Argentina is shorter around 90 mile
