SUPERIOR MISSION PERFORMANCE

LONG RANGE

With a typical range of 750 nm (over 1,300 km) in standard configuration and a large capacity cabin, the AW101 is the most capable maritime helicopter available in the world today. The AW101 has demonstrated over 900 nm continuous flying with auxiliary fuel tanks.

In addition to its already excellent range capabilities, the AW101 range can be further extended when using the optional Air-to-Air refuelling (successfully demonstrated with C-130 aircraft) and Hover-In-Flight refuelling capabilities (frequently used by AW101 maritime operators).

SHIP OR SHORE BASED

The AW101 routinely operates from ship or shore bases around the world. Existing variants are cleared to operate from a variety of vessels ranging from small Type 23 Frigates up to Helicopter Assault Carriers.

The flight characteristics of the AW101 are designed specifically for ship operations in extreme weather conditions. Large main and tail rotor thrust margins and excellent control response provides the agility needed for operations in rough sea states. The wide tricycle undercarriage and negative thrust capability ensures stability during landing and takeoff operations.

For maximum flexibility, the AW101 can be equipped with an (optional) Deck Lock system, enabling 360° rotation on the deck for optimal positioning. This feature, coupled with the complementary deck handling system assures maximum safety during deck movements in adverse conditions up to Sea State 6.

The AW101 can be equipped with an optional main rotor and tail rotor folding system, enabling stowage, transport and maintenance, even within a confined hangar space.
