I have been playing SH3 for a few weeks, and after reviewing some videos about manual targeting i found many interesting ways to get the TDC ready sooner.
For start, and very essential in every procedure.
1. IDENTIFY THE SHIP. Take note of the mast height (H), the length (L) and the draft (D)
Using the periscope I could count the number of ticks and I can find the range. The factor F depends on the magnification of the periscope (and the value used in different mods). I use with GWX and 10x the value of 0.315
2. The speed is found counting the number of seconds it takes to cross the ship through the mid line from bow to stern. The speed is then calculated with
V = L / secs * 2
(value rounded up) [ L is in meters and the result is in knots]
3. To get the AOB I use the ratio between length and mast height (L/H) and that should give me an equivalent legth in horizontal ticks by applying the formula.
HT = (L/H) * VT
where VT are the vertical ticks used to calculate the range.
That means if I see that the target is HT ticks in the periscope then it is at 90 degrees.
The proportion between the horizontal ticks viewed (h) and calculated ones (HT) gives me an approximate AOB.
h/HT AOB
1.0 90º
0.9 65º
0.8 53º
0.7 45º
0.6 37º
0.5 30º
The relation between this values are obtained using
sin(AOB) = h/HT
So if you got a intermediate calculated value, you could use a calculator to find the value of the AOB.
4. From the recognition book we obtained the draft, so we could set the torpedoes depth
All these methods are very dependable of the values sighted and the error margin propagates along this process. So they become approximate values. As I mention before, they can be used to prepare an attack in short time and at short distance (less than 2 km)
P.S. Sorry I didn't got the captured screens. Maybe someone could teach me how to do that.
