GWX's "uber" AI demystified

[Tobus]

The AI's ability to hear you depends on a few things:

A.) The state of the sea.
If the sea is calm, sonar conditions are greatly improved. If the sea is rough, sonar conditions are craptastic to say the least, and for you, this is good news.

b.) Engine RPMS.
It's not your speed per say that the AI qeues in on. Its your engines RPMs. When setting your speed, use the interior free cam and take a close look at your engines RPMS. 100 RPMs is usually the maximum i would go in a silent running scenario.

c.) Your position in relation to the escort. Looking back up at the picture of the aspect, you'll see a big semicircle around the destroyer. The area behind it, is its deafspot, or its baffeles. Its also deaf to anything DIRECTLY under it, at or around a radius of 10 meters. Depth charge attacks DO NOT mask your noise. Only when an escort is directly above you, or if you are directly behind an escort are you completely safe to use as many RPM's in your motors as your heart desires.

I was reading a book, "" U-boat killer" by retired destroyer captain Donald Macintyre (http://www.uboat.net/books/reviews.html/title/260), in which he clearly states that hydrophones were not used anymore on British subhunters since the 1e world war. ASDIC was the only means of hunting down u-boots. So what's this with "hearing" subs due to their enginenoise and other noises like pumps, reloading and repairwork? It seems to me everything of sound IS modelled in SH3/GWX.

Can you clarify?
