1. What is the Mortar Elevation Equation?

The mortar elevation equation calculates the optimal launch angle for a mortar to hit a target at a specific range, given the projectile's velocity and gravity. This is essential for accurate indirect fire in Arma Reforger.

2. How Does the Calculator Work?

The calculator uses the mortar elevation equation:

\[ elevation = \frac{\arcsin\left(\frac{range \times g}{velocity^2}\right)}{2} \]

Where:

\( range \) — Distance to target in meters
\( g \) — Acceleration due to gravity (9.81 m/s² on Earth)
\( velocity \) — Muzzle velocity of the mortar in m/s

Explanation: The equation calculates the angle where the projectile's parabolic trajectory will intersect with the target at the specified range.

3. Importance of Accurate Elevation

Details: Correct elevation calculation is crucial for effective mortar fire. Too high and you'll overshoot, too low and you'll fall short. This calculator helps find the perfect angle.

4. Using the Calculator

Tips: Enter the range to target in meters, the mortar's muzzle velocity in m/s, and gravity (default is 9.81 m/s² for Earth). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does my calculation show an error?
A: The error occurs when (range × gravity) exceeds velocity squared, which is physically impossible. Check your inputs.

Q2: How do I find my mortar's velocity in Arma Reforger?
A: Check the weapon stats in-game or consult the Arma Reforger documentation for your specific mortar type.

Q3: Does this account for wind resistance?
A: No, this is a simplified calculation that ignores air resistance. For more precise results, you may need to adjust based on in-game conditions.

Q4: Can I use this for other projectile weapons?
A: Yes, this works for any ballistic projectile where you know the velocity and want to calculate the elevation angle.

Q5: Why are there sometimes two possible solutions?
A: The equation can give two angles (a high arc and a low arc) that reach the same range. This calculator returns the lower angle (more direct trajectory).
