Colour triangle when I spot a ship

[wolffpl]

Maybe it`s a silly question, but what does that small triangle when you spot a ship with the periscope or in surface means?. Because sometimes is green then changes to yellow/orange or sometimes is red too. That drives me crazy.:damn:

It concerns how "good" your firing solution is on that vessel. Green means the torpedo is going to go straight out of the tube (give or take 5 degrees), amber means that the torpedo will have to make a turn before heading to its target and red means it can't turn enough to hit that vessel given your current heading.

Are that brings back memories of SH2. :/\\k: :/\\x: :/\\!! :/\\chop :/\\:

But it is a Godsend until you become proficient in targetting.

Manual targetting is an (almost) unknown field for me that I will learn some day...SH2 too :oops: (My undersea life born with SH3 sorry).
I thought that it had something to be like if the other ship detected your sub or not. Nothing closer from that :haha: .

Can I offer a clarification?

1) the green, yellow, amber, and red indicate how much of a turn -- the gyroangle - your torpedo will have to make to turn to the target. Green indicates a pretty straight shot, as Cherry says; red means an almost impossible (or impossible?) shot.

2) But green doesn't mean your firing solution is right. If you are firing an impact torpedo, but on 30 degrees Angle On Bow, your periscope/UZO may show green (because the torpedo can hit the target without turning), but the hit may glance off because of the angle. Nor does it take into account the depth of the torpedo.

3) Morever, the split between green/yellow is not cut in stone, it is just an indicator. You can make successful shots pretty consistently from 350 to 010, even though both of those gyroangles are yellow.

In sum: Green just means your torp doesn't have to go to gymnastics class to hit the ship. But you still need to worry about Angle on Bow, depth, and what pistol you are using.

The triangle also assumes that you are making calculations for an impact hit; if using magnetic settings those triangles are useless. a 30-60 aob is ideal for magnetics since it increases the surface area that the torpedo travels underneath the target and gives it the longest period of time to rise up to hit the target.

Normally you'll aim ~ 1 meter under the draft for a magnetic hit in calm seas, in rough seas that changes to 2-3 meters. If you'll notice in the event cam when the torpedo runs low but is running at a steeper angle (like more than 50 degree) it travels down the keel and you'll watch the eel slowly move upwards until it impact with the target.

Very interesting Desirableroasted and Tessa...there`s a lot of details to learn and that should be on some manual. GWX manual is very complete but I`m not sure if included these details (didn`t read the whole manual).

I think I have to differ, there, Tessa.

The green triangle means only that the torpedo will run a straight line (or close) out of the tube. It doesn't take AOB into account, precisely because you may have good reason to shoot at 30-40 AOB (magnetics, as you note). You can get a green triangle at any AOB.

Yes, I think it represents the chances of the eel making the correct turn to the prescribed gyro angle as it comes out of the tube.
