I think there's something misconfigured in my installation. Look how abruptly the ground textures disappears, this is very disturbing specially during night flights.So...FS9 issue or something misconfigured?

Make sure you have "Extended Terrain Textures" checked in your display settings--should fix the problem for you...-John

That was it in fact, feel so stupid, I was sure it was checked. Thanks a lot! ;-)
