The Great thing about SH3 and 4 is how scale-able it is. Beginners can lock a target in and allow the targeting to be done for them. That's useful if novice users lock a target in and then look at the gyro angles and settings to see where the game computer set them and learn targeting that way. This makes the simulation fun for basic users as well as more advanced players. Once a basic user learns the Trigonometry / Algebra principals associated with manual settings, they are ready to step up.
More advanced users Prefer to perform their own calculations to approximate as closely as possible the actual conditions and circumstances that a real u-boat / submarine commander would face.
To that end.
In computing Gyro angle:
Target Torpedo
--------- equals ----------
Deflection Bow
------------- equals -------------
Deflection ( Track - Deflection )
This can be used to calculate deflection angles with computed course
Target torpedo
________ Equals ________
Deflection ( Track - Deflection )
the Target part of the equation is the angle or difference between the targets course and the course the torpedo takes to intersect lines or intercept the target.
It can be useful to use a stationary target and use these equations and then use the automatic features and see if the solutions you calculated are the same as that derived by the computer.
Happy hunting.
Edit: I found an example where what I'm writing Isn't being screwed up.
