The passive sonar sensors (range/sensitivity/etc) are not impacted by the settings used for active sonar. Passive settings are a whole different kettle of fish that are a serious pain to tweak. I actually think they are OK. It seems like everything I've done to "improve" them only messes them up for the worse. They're also much more painful to test.
I also tried to figure out how to get escorts to use active before a submarine contact but couldn't figure out a way to do it. That's probably for the best because it might result in them Never turning off active. That much pinging would likely break game immersion even more than the lack of active we have now (imo).
Unfortunately, the escort AI in SH3--while artificial--is far from intelligent.
