Some torpedo and sonar questions....

[MaHuJa]

I believe the TIW warning is based on a very sensitive version of your sensors - as if he suddenly made some very loud sound, and if you could hear it (with "enhanced" sensors, the effect on the sonar displays are usually negligible), you get a TIW warning. If you're in a shadow zone (on the other side of the layer) you don't hear anything, so you won't get the TIW until you can. Which is usually after its closer - or you go to the other side of the layer.

The instant ping intercept has been fixed, but introducing a new issue of its own - you now don't hear a second ping emitted before the first reaches you.
