It was my understanding (due to reading a few other threads) that SH4 isn't programmed as you might think with regards to enemy AI and active/passive sonar. In my head, if I was setting SH4 up, I'd have the escorts concentrate on passive sonar, all the time... and use active sonar if/when they suspect that a sub is in a given area. Use active to pinpoint, etc.
Somebody in one of those other threads suggested that the above design is not what SH4 does... if you're within the cone of active sonar, at the right aspect, then the escort pings. Regardless of whether we think the escort should be pinging at that particular moment or not.
At that point, since you're in the cone and with your beam to the enemy, he's able to locate you. Rotate off the beam, and he can't... 'cause the game is saying he can't find you if he did ping.
That's a better way to phrase SH4's method, actually... if your sub is in such a position that if the escort could locate you via ping, then he will. If not, then the escort has to rely on the passive to locate you.
This is probably all complicated by the skill of the escort, too... I've had escorts that have detected me in almost unbelievable situations

, and others that should've pounced on me like a cat on a mouse, but continued by, oblivious.
Somebody feel free to tell me I'm wrong, 'cause I'd love to hear it... I'm tired of mentally picturing sonar ranges & aspects in my head on convoy approaches, wondering whether I'm going to blunder in someone's active sonar cone.
