Thanks santobr, I tried this option but it doesn't seem to change anything.
Could someone please explain some of the more cryptic contents of the settingsXXX.dat file?
[AF_OFF] and [Airstart] seem self-explanatory, but I'm not sure about the contents of the [Distance] section: AFRange, ClustersRange, ClustersRadius and ClustersCount. What do they do? Are there any other available tweaks?
AFRange=3000 (default)
Objects in this Range around the airfield will be recognized as airfield targets and not, for example, as artillery or depot. It was necessary to add this setting for the Guadalcanal part of my Solomons campaign, because with the default setting all objects in the small American perimeter on the island were recognized as airfield objects. The setting is useful for other campaigns too, whenever an airfield is inside a small pocket, Stalingrad could be an example.
ClustersRange=2000 (default)
The distance between target clusters. If within this range a cluster already exists, a second cluster isn't formed.
ClustersRadius=1000 (defaul)
Radius in which objects are recognized as part of a target cluster.
ClustersCount=10 (default)
Number of objects that need to be in a cluster to be recognized as target for a mission. I am not sure if this is really needed for ETO campaigns, but in PTO campaigns it is useful.
