In the IRON NEST Heavy Turret Simulator, I do not need to deal with the complex ballistics of the real world when calculating my shots. If I want to fire without using the TDC-style computer, or if I reach the mission where the computer is damaged, I can calculate the correct elevation angle with a simple formula.
How to Calculate Elevation Without the TDC
When I need to calculate my shot manually, I only need to know the distance to the target and the number of charges I want to use. The formula gives me the elevation angle directly.
Elevation Formula
The formula I use is:
Elevation = Distance × 0.012 / Number of Charges
With the target distance and the number of charges, I can quickly calculate the elevation angle without relying on the computer.
Elevation Calculation Example
For example, if I know the enemy is approximately 6470 meters away, I can use 2 charges because they allow me to shoot up to 10 km.
First, I calculate:
6470 × 0.012 = 77.64
Then I divide the result by the number of charges:
77.64 / 2 = 38.82
This gives me an elevation angle of 38.82. I can also check the result on the in-game computer, which gives me the same angle.
Another Elevation Example
If my target is 4300 meters away and I want to use 5 charges, I use the same formula:
4300 × 0.012 / 5 = 10.32
In this case, my required elevation angle is 10.32.
What I Need to Calculate the Shot
Basically, all I need to know is the distance to my target. The red pencil helps me determine that distance, and once I have it, I can use the formula to calculate the elevation angle.
Enjoy, operators.
