HUD
The helicopter HUD is displayed for both the pilot and co-pilot whenever they are seated in a cockpit seat. The dial cluster shows:Damage Panel (top-left)
The damage panel is a separate top-left panel, not part of the dial cluster. It carries the helicopter’s name, its overall health bar, the six damage zone indicators, and three status icons:Because those three icons live on the damage panel, hiding the panel hides them too. Press
H to toggle the panel for yourself (client-side, your choice only), or set features.damageZonePanelEnabled = 0 in mod_config.json to remove it server-wide.Cockpit Hint Row
Below the cluster, a single hint row shows the currently selected cockpit action — ramp, landing gear, sling, winch or door — cycled with the mouse wheel and triggered withF. See the Controls Reference.
While a sling load is hooked, the sling row also shows the live rope length in metres, so you can see exactly where the winch has the load.

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 (reworked in v0.3.0) — land the helicopter on or right beside a working fuel station (within ~12 m of a pump — the station roof counts), walk to the helicopter’s fuel refill point with empty hands, and hold F on the “Refuel at Fuel Station” action. No container needed — every airframe fills from empty to full in roughly 100 seconds regardless of tank size. Works with vanilla and Enoch stations, plus pump mods built on the vanilla fuel-station class.
Accepted fuel sources:
Refuel amounts and drain speed per container type are configurable in
mod_config.json. See Global Settings for the full table.
CZAutoz_HeliDrum still exists as a deprecated legacy alias of CZ_HeliDrum so old types.xml entries keep working. Use CZ_HeliDrum in anything new.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.
