## 1. Overview
|
|
The Advanced Ballistics module improves internal and external ballistics.
|
|
|
|
### 1.1 Features
|
|
- Drag modelling based on real-world ballistic coefficients.
|
|
- Ambient air density (air pressure, temperature, humidity) affects drag.
|
|
- Wind affects drag and deflects the trajectory.
|
|
- Wind speed varies with altitude.
|
|
- Terrain features, buildings and other objects disrupt the wind.
|
|
- [Magnus effect](https://en.wikipedia.org/wiki/Magnus_effect) (spin drift)
|
|
- [Coriolis effect](https://en.wikipedia.org/wiki/Coriolis_effect) and [Eötvös effect](https://en.wikipedia.org/wiki/Eotvos_effect) (Earth rotation)
|
|
- Loss of stability during transonic flight.
|
|
- Variable muzzle velocity based on powder burn rate and barrel length.
|
|
- Bullet trace effect for supersonic bullets (light refraction due to air pressure waves).
|
|
- A protractor for quickly measuring the inclination angle.
|
|
|
|
|
|
## 2. Usage
|
|
|
|
### 2.1 Enabling Advanced Ballistics
|
|
|
|
#### 2.1.1 OPTIONS → GAME → CONFIGURE ADDONS

|
|
#### 2.1.2 CBA Settings System
|
|
- [CBA Settings System](https://github.com/CBATeam/CBA_A3/wiki/CBA-Settings-System)
|
|
|
|
#### 2.1.3 Enabled in-game ?
|
|
- Pick up a [Range Card]({{ site.baseurl }}/wiki/feature/rangecard.html) and open it.

|
|
|
|
### 2.2 Protractor
|
|
- You need a compatible weapon.
|
|
- Press <kbd>Ctrl</kbd>+<kbd>⇧ Shift</kbd>+<kbd>K</kbd>.
|
|
- Red line indicates the current inclination angle in degrees.
|
|
- Protractor will disappear if you lower or holster your weapon.
