# MH-47G Chinook
> 27-seat tandem twin-rotor heavy lifter — the largest, fastest and highest-flying helicopter in the mod. Two-stage rear ramp, a stand-up walkable cabin, and a 10,000 kg dual-hook sling.
The MH-47G Chinook is the largest helicopter in the mod and the only tandem twin-rotor airframe, carrying 27 people. Added in **v0.3.9**, it is also the fastest, the highest-flying and by far the strongest lifter in the fleet — the only aircraft that can sling the heaviest vehicle classes. Two counter-rotating lift discs replace the tail rotor entirely, and the cabin is the only one in the mod you can **stand upright in**: walk in off the rear ramp, pick a seat anywhere in the hold, or stay on your feet while the aircraft flies.

## Tandem Twin Rotor
The Chinook has **no tail rotor**. Lift comes from two counter-rotating discs — one forward, one aft — whose torque cancels out, so there is no anti-torque pedal dance to manage. **Yaw is produced by differential cyclic** between the two discs instead.
This changes the damage model in one important way:
On the Chinook, the **Rotor 2** damage zone is the **rear lift disc** — not a tail rotor. Losing it is not a spin emergency; it is a loss of half the aircraft's lift, and the airframe pitches out of control rather than yawing.
Downwash is modelled per disc: the Chinook kicks up **two dust clouds**, one under each rotor, and a disc that has been shot out stops raising its own.
## Rear Ramp
The Chinook has an openable rear loading ramp with a **true two-stage fold** — the lower ramp swings down while the upper section slides flush into the deck, leaving a clear opening across the full width of the hold.
* Use the **Open/Close Rear Ramp** action to operate it
* The action is blocked while the ramp is already mid-travel — wait for it to finish before issuing another command
* Available to **pilot, co-pilot, and players standing outside** near the rear of the aircraft
* All 25 cargo seats are boarded from **inside the hold** — walk in off the ramp and take any free seat
* Ramp open/close events are recorded in the activity log when `logging.CZAutoz_logActivity = 1`
## Stand-Up Cabin
The Chinook is the **only helicopter in the mod with a stand-up walkable cabin**. Every other airframe with an interior crouch-locks the player; in the Chinook you walk the hold fully upright, in flight or on the ground.
It also supports Cabin Mode, the same system as the UH-1H and MH-60L Black Hawk:
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 hold, moving with the helicopter during flight
3. Full WASD movement, weapon use, and ADS inside the cabin
4. At any time, use **"Return to Cockpit"** to return to your seat (original seat if free, otherwise alternate)
`features.cabinModeEnabled` defaults to `1`, so the **Move to Cabin** action is available out of the box. Server owners can disable it globally by setting `features.cabinModeEnabled = 0` in `mod_config.json` — when off, the action does not appear at all.
See [Cabin Mode](/features/cabin-mode) for full details.
## Sling Loading
The Chinook is the fleet's heavy lifter, with a **10,000 kg lift class** — the highest in the mod, and the only one that can move the heaviest vehicle classes.
* It carries loads on **two hooks**, fore and aft (`sling_hook1` and `sling_hook2`), with a chain bridle to the front and rear of the load so long vehicles ride level and follow the airframe. The AW101 Merlin is the only other airframe with dual hooks
* Its **winch hardware is modelled on the airframe** — the rope and chain gear reveals when a load is hooked, as it does on the UH-1H and Black Hawk
* The lift class is `sling.maxKg` in the helicopter's config file; loads over the limit simply cannot be hooked
## Landing Gear
The Chinook has a **fixed four-wheel chassis** — two forward wheels and two aft. The landing gear does not retract or extend; it remains in the deployed position at all times.
## Door / Wheel Item Classnames
| Item Classname | Description |
| ---------------------------- | ------------------- |
| `CZ_MH47GChinook_Pilot` | Pilot door |
| `CZ_MH47GChinook_CoPilot` | Co-pilot door |
| `CZ_MH47GChinook_FrontWheel` | Forward wheels (×2) |
| `CZ_MH47GChinook_RearWheel` | Aft wheels (×2) |
Door classnames are variant-specific (e.g. `CZ_MH47GChinook_Pilot_NightStalkers`, `CZ_MH47GChinook_CoPilot_UnitedNations`) — add these to your `types.xml` if you want doors to spawn with the helicopter. Wheels are shared across all variants.
## Cargo
Alongside its built-in storage, the Chinook accepts up to **10 extra cargo modules**, the same as the rest of the fleet.
