How to Refuel
There are two ways to refuel a helicopter: From a container — hold a fuel container, approach withinfuel.refuelDistance metres of the helicopter, and look at the fuel refill point on the helicopter’s model. The refuel action will appear — activate it to transfer fuel from the container into the tank.
At a fuel station — park near a working fuel station and use the built-in pump-refuel action. No jerry can is needed, and the fill rate is faster than a container.
Accepted fuel sources:
Refuel amounts and drain speed per container type are configurable in
mod_config.json. See Global Settings for the full table.
Helicopters spawned by the Central Economy (
types.xml / events.xml) start with a partial fuel load rather than empty or full.Refuel Settings
Fuel Warning System
Audio warning beeps alert the crew when fuel is running low:- Beeps begin at the configured fuel fraction threshold
- The beep interval shortens as fuel continues to drop — urgency increases
- Both pilot and co-pilot hear the warning
The fuel warning threshold lives in
mod_config.json under gameplay. Audio volume settings (audio.engineVolume, audio.rotorVolume, audio.warningVolume, audio.crashVolume) are configured per variant in each helicopter’s JSON file under the audio section. See Per-Helicopter Settings for the full table and per-variant tuning details.
