# Aircraft Behaviour

## Aircraft behaviour

This system changes how aircraft behave in flight. It adds stronger turbulence, improved glide physics, GPWS warnings, and weather-based hazards.

You can tune most values per aircraft and per weather type. This lets a crop duster feel very different from a military jet.

### Turbulence

Aircraft experience stronger turbulence than in standard GTA. The effect is designed to make different aircraft feel heavier, lighter, or harder to control depending on their role.

You can configure:

* camera shake multiplier per aircraft
* turbulence intensity by weather type
* different handling profiles for different aircraft classes

Weather also affects how much turbulence an aircraft experiences. This gives storms and rough conditions a much larger impact on flight.

### Glide physics

Planes use improved glide physics. This makes forced landings more believable and gives pilots a better chance of recovering after an engine failure.

In practice, a total engine failure does not always mean an immediate crash. If you keep control of the aircraft, you may still be able to glide to a landing.

### GPWS

GPWS stands for **Ground Proximity Warning System**. It gives the pilot audio warnings when the aircraft enters a dangerous flight condition.

You can configure warning limits per aircraft, including:

* bank angle limit
* overspeed limit
* maximum operating height
* terrain warning height
* sink rate warning threshold

### Warning types and consequences

Ignoring warnings can damage the aircraft or put the flight at immediate risk.

#### Overspeed

If you do not reduce speed after an overspeed warning, the aircraft can start to break apart. Landing gear is especially vulnerable if it is still deployed. If the overspeed is under a prolonged duration, parts of the wings may start to break apart, such as the rudder and flaps. 

#### Terrain

This warning means the aircraft is too close to the ground. If you do not correct course or climb, impact is likely.

#### Sink rate

This warning means you are descending too fast. If you keep descending at that rate, you may lose control or enter an overspeed condition.

#### Bank angle

This warning plays when the aircraft tilts too far

#### Best operating height

Each aircraft performs best within its intended flight envelope. At the right altitude, turbulence stays manageable and performance remains stable.

#### Maximum operating height

Each aircraft also has a ceiling. Light aircraft cannot follow high-performance jets indefinitely, which creates more varied pursuits and more realistic aircraft roles.

#### Lightning strikes

Aircraft can be struck by lightning in thunderstorm conditions. A strike can damage the aircraft and may cause an engine failure.

### Configuration overview

Most aircraft behavior can be tuned in the config file. A typical setup includes:

* per-aircraft turbulence and warning values
* per-weather turbulence intensity
* aircraft-specific performance limits and safety thresholds

Use lower values for small civilian aircraft and higher values for large or high-performance aircraft. This keeps each aircraft type distinct without making every flight feel the same.
