What controls land proximity?

[Hitman]

Looking for some assitance here, for an idea I want to study a bit more.

Anybody knows/has stumbled upon what file/value tells the game when land is closeby and causes thus the time compression to be limited? ("Landproximity" in the time compression cfg file) :hmm:

What I'm trying to do is expand that "Land proximity" boundary to the air coverage area from land based aircraft, and limit time compression to 256x inside it. That would limit you to be always only at the maximum time compression that makes the game play correctly (Preventing the high TC no-spawn aircraft bug ) without having to guess if you are far enough or not from air coverage to enable higher TC and such.

Since locating a convoy an lurking around it will already make TC go down, it would also reflect well the air coverage of those convoys from land bases (Allied airplanes did not search the whole atlantic for U-Boats, they just did it in shore areas where U-Boat transit was necessary -like the Biscay Bay- and in the convoy lanes).

Thanks
