AS355 NP AS355 NP When Performance Meets Affordability With excellent handling, robustness and ease of maintenance, the AS355 NP incorporates twin-engine added reliability and performance—making it ideal for police and parapublic missions, as well as demanding operations over water, rugged terrain and urban areas. Renowned for its low operation and maintenance costs, this helicopter benefits from the reliability and safety of its two Turbomeca Arrius 1A1 engines, and is equipped with a full authority digital engine control (FADEC) system. The AS355 NP is fully IFR certified and can be fitted with a 3-axis autopilot, along with mission-specific equipment for medical evacuation and law enforcement operations. The helicopter also offers excellent maneuverability, high speed and low vibration levels. An unobstructed cabin and forward-looking seats provides excellent visibility for all passengers, and the AS355 NP’s very low vibration levels make it a perfect choice for corporate transportation. The flexible, reliable and economical AS355 is one of the most successful twin-engine helicopters in the world, with 760 AS355/AS555 delivered and over 3.5 million flight hours achieved. Technology The AS355 NP is equipped with two powerful Turbomeca Arrius 1A1 engines and a full authority digital engine control (FADEC) system that provides automated engine control and monitoring. With this state-of-the-art system, the pilot has no engine parameters to monitor during the automatic starting sequence, which thereby eliminates the risk of engine deterioration. In the event of engine failure during flight, the maximum emergency power is automatically and instantaneously provided to the operating engine, enabling the pilot to concentrate on the external environment while the FADEC takes control. The AS355 NP provides excellent OEI performance: It is capable of taking off at MTOW in Cat A from a helipad at temperatures up to 25° C at sea level. Just as other helicopters in the Ecureuil family, the AS355 NP is also equipped with a Vehicle and Engine Multifunction Display (VEMD), which optimizes the human-machine interface, and a standard avionics suite for day and night VFR operations that includes a GPS color map display and a redundant COM/NAV. The aircraft is fully IFR certified (single/dual pilot) and can be fitted with a 3-axis autopilot as well as mission-specific equipment. News gathering Medical service Multipurpose Missions The Reliable Twin-Engine AS355 NP Equipped with state-of-the-art technology, the twin-engine AS355 NP can perform all type of missions including law enforcement and public services both day and night, whether over water, congested areas or hostile environments. The AS355 NP’s unobstructed cabin and forward-facing seats guarantee excellent visibility for passengers. As an option, footsteps and sliding doors can be installed to provide easy access to the wide cabin. The helicopter is equipped with an array of certified equipment to perform a wide range of operations with optimal efficiency, including: • Surveillance • Command and control • Light Search and Rescue • Border patrol • Aerial support for ground operations • Coastal surveillance. The helicopter’s open cockpit concept and low vibration levels make it possible to install fully-integrated law enforcement instrument panels and tactical consoles. Installing optional equipment is also simple in order to effectively perform missions such as: • Harbor pilot transportation • Sling load operations • News gathering • Power line maintenance and repair • Bungee jumping • Radioactivity measurement. For EMS operations, the AS355 NP can carry one patient and two medical attendants in addition to a pilot and a considerable payload for the most demanding high and hot missions, over a distance of 731 km (395 NM) and at a cruising speed of 222 km/hr (120 kts). Its high-performance rotors make it easy to maneuver the helicopter even in tight spaces, and offer a high level of safety when flying above urban environments. Just as the other helicopters in the Ecureuil family, the AS355 NP can be equipped with a large selection of medical kits and can be operated from elevated hospital helipads in congested areas. When fitted with a Stylence® interior layout, the AS355 NP is an exceptional choice for efficient and comfortable passenger transportation.
