Aviation Core is a shared framework for helicopters and aircraft in Project Zomboid Build 42.20+. It provides flight controls, aircraft handling, spawning, persistence, fuel management and HUD systems for compatible mods. The library does not add any aircraft on its own and remains under development.
Contents
Aviation Core is a technical framework for Project Zomboid that provides the systems required to implement helicopters and other aircraft.
Designed for Build 42.20 and newer, the library handles essential aviation mechanics, including flight controls, vehicle behavior, fuel management and interface elements.
Instead of implementing the same systems independently, compatible aircraft mods can use this shared foundation.
Important: Aviation Core does not add helicopters, airplanes or any other aircraft by itself. You need a separate compatible vehicle mod to use its functionality.
Main Features
The framework includes several interconnected systems for aviation modifications.
| System | Function |
|---|---|
| Flight Controls | Handles aircraft control inputs |
| Aircraft Handling | Provides shared flight behavior |
| Spawning | Supports aircraft appearing in the game world |
| Persistence | Manages aircraft state persistence |
| Fuel Systems | Provides fuel-related functionality |
| Aircraft HUD | Displays flight-related interface elements |
| Mod Integration | Provides shared systems for compatible aircraft addons |
Flight Controls and Handling
The library supplies the underlying mechanics for controlling supported flying vehicles.
Individual aircraft modifications can use these systems to implement their own flight behavior.
The exact controls and handling characteristics depend on the aircraft addon being used.
Spawning and Persistence
Aviation Core includes functionality for aircraft spawning and persistence.
These systems provide a foundation for managing aircraft in the game world without requiring every compatible mod to implement the same underlying features independently.
Fuel Management and HUD
The framework also provides systems for aircraft fuel handling and a dedicated flight interface.
Specific displays, controls and fuel behavior may vary depending on how individual aircraft modifications use these features.
How to Use Aviation Core
This modification primarily serves as a dependency for other addons.
- Install Aviation Core through Steam Workshop.
- Install an aircraft modification that requires the framework.
- Enable both components in Project Zomboid.
- Follow any additional installation instructions provided by the aircraft developer.
Installing Aviation Core alone will not introduce new vehicles into the game.
The original description does not specify a complete list of supported aircraft.
Compatibility and Development Status
| Feature | Status |
|---|---|
| Game version | Build 42.20+ |
| Helicopter and aircraft systems | Available for compatible mods |
| Standalone aircraft | Not included |
| Multiplayer | Not specified |
| Existing-save compatibility | Not specified |
| Development status | Work in progress |
The developer is continuing to improve the framework, so bugs and compatibility issues may occur.
Support for additional aircraft modifications is also planned.
Aviation Core provides the technical foundation for expanding aviation in Project Zomboid, allowing compatible developers to build aircraft around a common set of flight, fuel and interface systems.
