HUD
The helicopter HUD is displayed for both the pilot and co-pilot whenever they are seated in a cockpit seat. It shows:
| Element | Description |
|---|
| Airspeed | True airspeed in knots — smoothed to remove needle and number jitter |
| Altitude AGL | Height above ground level in feet |
| Health Bar | Current helicopter HP |
| Pilot Control Indicator | Green when you hold flight control, red when the other cockpit seat holds it |
| Autohover Status | Whether Autohover is currently active |
| Light Status Icons | Whether the spotlight and navigation lights are on or off |
Fuel System
Fuel Capacity & Burn Rate
| Helicopter | Tank Capacity | Burn Rate | Approx. Flight Time |
|---|
| MD500 Civilian | 242 L | 126 L/hr | ~1h 55m |
| MH-6 Little Bird | 235 L | 112 L/hr | ~2h 06m |
| SA342M Gazelle | 448 L | 128 L/hr | ~3h 30m |
| UH-1H Iroquois | 833 L | 333 L/hr | ~2h 30m |
| MH-60L Blackhawk | 1,362 L | 545 L/hr | ~2h 30m |
| AW101 Merlin | 3,222 L | 644 L/hr | ~5h 00m |
Unlimited Fuel
Set fuel.burnLPH to 0 to disable fuel consumption entirely.
fuel.burnLPH = (fuel.maxCapacity / desired_flight_minutes) * 60
Example — UH-1H for exactly 2 hours of flight:
fuel.burnLPH = (833 / 120) * 60 = 416.5
How to Refuel
There are two ways to refuel a helicopter:
From a container — hold a fuel container, approach within fuel.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:
| Source | Notes |
|---|
CanisterGasoline (jerry can) | Standard refuel. Default: fills 10% of any tank per full can. |
CZAutoz_HeliDrum (Helicopter Fuel Drum) | Large drum. Default: fills 50% per drum — 2 drums to fill any helicopter from empty. |
Bottle_Base items | Water bottles, glass bottles, etc. Very small fill per bottle. |
| Fuel station (built-in) | Vanilla, Enoch, or a Simple Gas Pump — pump-refuel directly with no container, at a faster fill rate. |
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
| Setting | What it does | Default |
|---|
fuel.refuelOnRestart | 1 = helicopter refuels to full on each server restart. Does not affect fresh spawns — admin-spawned helicopters always respect the spawner’s fluid choice. | 1 |
fuel.refuelDistance | Max distance in metres for the refuel action to appear | 5.0 |
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
| Setting | What it does | Default |
|---|
gameplay.fuelWarnThreshold | Fuel fraction at which beeps begin. 0.20 = starts at 20% remaining. Set in mod_config.json. | 0.20 |
audio.warningVolume | Volume of the fuel warning beep and rotor emergency alarm | 1.0 |
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.
