# UH-1H Iroquois

> 5-seat helicopter with Cabin Mode. Pilot or co-pilot can leave their seat and walk the cabin while airborne.

The iconic Huey. The UH-1H is a 5-seat medium helicopter and one of two aircraft in the mod with Cabin Mode — the pilot or co-pilot can leave their cockpit seat and walk freely inside the cabin while the helicopter is in flight.

## Door Item Classnames

| Door Item Classname    | Position         |
| ---------------------- | ---------------- |
| `CZ_UH1H_Nasa_Pilot`   | Pilot door       |
| `CZ_UH1H_Nasa_CoPilot` | Co-pilot door    |
| `CZ_UH1H_Nasa_Cargo1`  | Left cargo door  |
| `CZ_UH1H_Nasa_Cargo2`  | Right cargo door |

Each variant has matching door classnames (e.g. `CZ_UH1H_MilitaryPolice_Pilot`, `CZ_UH1H_StealthBlack_Cargo1`).

## Cabin Mode

The UH-1H supports Cabin Mode:

1. While seated as **pilot or co-pilot**, look back to find the **"Move to Cabin"** action
2. Activate it — your character leaves their cockpit seat and walks freely inside the cabin, moving with the helicopter during flight
3. Full **WASD movement**, **weapon use**, and **ADS** are available inside the cabin
4. At any time, use **"Return to Cockpit"** to return to your seat (original seat if free, otherwise alternate)

<Warning>
  **Cabin Mode is still being reworked and is OFF by default as of v0.2.4.** `features.cabinModeEnabled` now defaults to `0`; when off, the **Move to Cabin** action does not appear at all. In-flight Move to Cabin does not yet hold the pilot/co-pilot inside the cabin correctly — **please keep it disabled until a future hotfix** completes the rework. It can be re-enabled server-wide by setting `features.cabinModeEnabled = 1` in `mod_config.json`.
</Warning>

See [Cabin Mode](/features/cabin-mode) for full details.
