AS355 NP
When Performance
Meets Affordability
With excellent handling, robustness and ease
of maintenance, the AS355 NP incorporates
performance—making it ideal for police and
parapublic missions, as well as demanding
operations over water, rugged terrain and
urban areas.
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
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
AS355/AS555 delivered and over 3.5 million
flight hours achieved.
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.

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.
