Design | ||||||||||||||||||||||
Known
worldwide for its sleek fuselage and powerful performance, the AS365
N3 is tailored for a full range of missions, including law enforcement
and surveillance, medevac operations, VIP transportation, passenger
shuttles to offshore oil/gas platforms and port ship pilot transfers
(capable of heli-hoist operations while hovering with one engine out).
The AS365 N3+’s wide lateral access to the cabin, combined with
the enlarged bubble sliding doors and the class 1 rescue hoist, make
it perfectly adapted to SAR operations. The large, unobstructed cabin
can comfortably accommodate up to 11 passengers and 2 pilots. The cabin
is easily accessed by large forward doors. |

Propulsion | ||||||||||||||||||||||
The
AS365 N3+ is powered by two Turbomeca Arriel 2C turbine engines fitted
with a Full Authority Digital Engine Control (FADEC) system. Not only
can this aircraft take off in ground effect at maximum weight and in
temperatures of up to +50°C, but it is also capable of taking off
with a full load from sea level in Category A conditions. The AS365
N3+ incorporates the all composite FENESTRON® tail rotor that provides
high manoeuvrability, exceptional efficiency at all speeds, unparallel
ground crew safety and low sound level. Its sound emission is rated
at 3.1 EPN decibels below the International Civil Aviation Organization
(ICAO) standards, making it the quietest helicopter in its category. |

The
AS365 N3+ is fitted with a digital four-axis autopilot and outstanding
state-of-the-art avionics equipment (e.g. FMS, GPS, Proline radio 21,

Mission capabilities | ||||||||||||||||||||||
The AS365
N3+ offers exceptional speed and endurance to perform all kinds of police
operations ranging from patrol, airborne surveillance, SAR missions
and special operations. The two powerful Turbomeca Arriel 2C engines
provide higher reliability and safety margins than any other aircraft
in this category. The AS365 N3+’s compact size and exceptional
maneuverability allow police forces to operate in the most confined
areas. Low vibration levels, thanks to a digital 4-axis autopilot, make
it possible to install all the equipment necessary for law enforcement
missions and provide optimal comfort for long patrols. The simple design
of the AS365 N3+ reduces the need for maintenance, which, in turn, reduces
operating costs and enhances availability. The AS365 N3+ can be equipped
with a wide range of certified equipment to perform all police operations
which can include surveillance systems, command and control equipment,
day/night infrared camera, rapelling system, auxiliary fuel tank and
night vision goggle. |
