The AW101 Merlin is the largest and heaviest helicopter in the mod, capable of carrying 18 people. With its rear loading ramp, pilot-operated retractable landing gear, and large enclosed fuselage, it is purpose-built for large group transport. All passengers board and exit through the rear fuselage — the rear ramp is essential for efficient boarding.

Rear Ramp

The Merlin has an openable rear loading ramp:
  • Use the Open/Close Rear Ramp action while grounded to operate it
  • The ramp cannot be operated mid-flight — the action is blocked while airborne
  • 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 16 passengers enter and exit through the rear of the fuselage
  • Practical for large group boarding — land, open the ramp, load up, close and lift off
  • Ramp open/close events are recorded in the activity log when logging.CZAutoz_logActivity = 1

Retractable Landing Gear

The Merlin has a retractable tricycle landing gear operated by the pilot using the F key (landing gear action) from the pilot seat. Raise the gear after takeoff and lower it before landing.
Landing gear always deploys to the lowered position on server boot, regardless of its state at shutdown. Pilots must raise the gear manually after each takeoff.
Landing gear deploy/retract events are recorded in the activity log as LANDING_GEAR when logging.CZAutoz_logActivity = 1.

Seat Exit Free Walk

The Merlin does not use the Move to Cabin / Return to Cockpit system. Instead, because it has a fully enclosed fuselage, the standard “Get Out” action from any seat — including pilot and co-pilot — exits the player into the aircraft interior rather than outside. The DayZ engine automatically links them to the helicopter’s coordinate space, and they can walk freely mid-flight. Getting back into any available seat works normally mid-flight. To actually leave the aircraft, the rear ramp must be open. Players who exit into the interior with the ramp closed remain inside until it is opened.
