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 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.
