Designed to deliver excellent performance throughout the flight envelope, Airbus Helicopters' H145 (formerly called the EC145 T2) is the latest member of its 4-ton-class twin-engine rotorcraft product range - with designed-in mission capability and flexibility, especially in high-and-hot operating conditions. Compact in size, this helicopter's small footprint and large and flexible cabin make it the aircraft of choice for a variety of civil missions.

The H145 joins Airbus Helicopters' multi-purpose EC145/BK117 family, from which some 1,000 rotorcraft are in service worldwide - logging a combined total of more than four million flight hours.
Bringing a large cabin, a compact airframe, and powerful engines, the H145 responds to a multitude of mission needs.
Enhancements incorporated in the H145 include Airbus Helicopters' innovative Helionix avionics suite and 4-axis autopilot; increased performance through the Arriel 2E engines; an anti-torque system with the latest version of the company's signature Fenestron shrouded tail rotor; and a new tail gearbox as well as an upgraded main gearbox.

The H145's designed-in modularity and large unobstructed cabin with flat floor contribute to the helicopter's flexibility for a full range of applications, accommodating up to 8 passengers in standard configuration and 10 passengers in a higher density configuration, plus one or two pilots.
This multi-purpose rotorcraft can be tailored for emergency medical services and police duties, along with aerial work, passenger transport, including business and private aviation, and airlift flight to offshore platforms. For multi-mission operators, the H145 can be reconfigured for different roles quickly and easily.

The H145's enhanced Arriel 2E powerplants and their dual full-authority digital engine control (FADEC) - along with the helicopter's upgraded main and tail rotor systems - guarantee an unprecedented level of performance in both hover and one-engine inoperative (OEI) conditions.
The Fenestron technology brings to the H145 benefits such as improved flight and ground safety, enhanced anti-torque control efficiency, reduced power demand in forward flight, and lower noise and vibration levels.
For its use on the H145, the Fenestron has a new-design tail gearbox with lower maintenance costs, and incorporates a duplex tail rotor actuator and dual hydraulic circuits - installed in a new, damage-tolerant all-composite tail boom.

Airbus Helicopters' new Helionix avionics suite provides undisputed superiority for in-flight envelope protection, pilot assistance and situational awareness - resulting in unprecedented flight safety levels.
Meeting the latest international avionics standards, the Helionix installation incorporates the most innovative alerting and self-monitoring system.
Additionally, the H145 is equipped with the most advanced dual-duplex, four-axis autopilot specifically designed for helicopters. This offers high flight stability and precision, unique flight envelope and over-limit protection, automated takeoff, and fully-coupled approaches to hover, among other benefits.
Further contributing to operational safety are the rotorcraft's high-set main rotor and tail boom, and the Fenestron shrouded tail rotor.

Building on Airbus Helicopters' extensive experience gained with the BK117/EC145 helicopter family, the H145's maintenance procedures optimize the intervals between periodical inspections, ensuring increased availability and reduced operating costs.
The optional helicopter usage monitoring system (HUMS) keeps track of the engine's health in accordance with usage conditions, resulting in further availability and enhanced cost-effective maintenance.

Law enforcement
The H145 is always "ready for duty", capable of being equipped with a modern mission management system for a variety of police operations. Fast and reliable, the helicopter can rapidly transport up to 11 officers to the scene. It is likewise ideal for the transport of special police forces. Primary roles include and patrol, surveillance, and rescue missions, supported by the roomy, flexible cabin, and installation of forward-looking infrared (FLIR) and daylight cameras that are controlled by an operator who also handles communications and data exchange with ground-based police resources. Other equipment opportunities include a powerful searchlight, external hoist, and simultaneous external roping capability for two persons - one on each side. Equipment under development includes a tactical mission management system, connectivity features and an EOS (electro-optical system) digital camera. Further contributing to the helicopter's operational flexibility is its night vision goggle-compatible cockpit with a night vision imaging system (NVIS).

Emergency medical services
Building on the worldwide use of Airbus Helicopters'H145 and predecessor BK117 in emergency medical services, the H145 is well tailored for primary/secondary missions and intensive care transport - benefitting from the easy and safe loading/unloading of patients through wide side sliding doors and the large rear clamshell doors. Its spacious, unobstructed cabin was specifically designed to meet the requirements set by national medical regulatory agencies. The cabin accommodates one or two wheeled stretchers with partial or full suites of medical equipment for operation by up to three medical personnel. The helicopter benefits from multiple EMS cabin interiors, which were designed in cooperation with one of the world's leading EMS providers. Comfort for both patients and the crew is ensured with the H145's turbine-smooth ride. The helicopter's extremely low external sound levels allow neighborhood-friendly operations around hospitals and in urban areas.

Offshore oil and gas transport
Long-range flight capability and the capacity to carry 8 passengers are attributes that make the H145 a natural for offshore oil and gas airlift missions. Adding to this are the helicopter's high performance and small footprint. The H145 can operate in performance class 1 conditions, while its compact airframe contributes to its ability to operate in the confined environments of oil/gas platform helipads. The equipment list covers all elements required for offshore operations, including a color weather radar, emergency flotation system, helicopter emergency egress lighting (HEEL) and automatic deployable emergency locator transmitter.

Business and commercial aviation
The H145 brings together speed and comfort to create the optimum "time machine". The spacious and flexible cabin can be outfitted with interiors that bring a touch of class for passengers - including the "Stylence" design developed by Airbus Helicopters for a highly functional work environment. A step higher in elegance is the leather and wood interior, designed by Mercedes-Benz. Excellent visibility is provided for both pilots and passengers through the large windows offering stunning views. As the quietest helicopter in its class, the H145 can land at work sites, in office zones and urban areas, bringing passengers where they want to go. It is one of the only aircraft authorized to fly in the Grand Canyon, along with the H135 and EC135. Ample space is available for luggage, which is easily loaded through the rotorcraft's rear clamshell doors. There is also an advanced in-flight entertainment systems and subtle ambient lighting.

Aerial work
The H145's power reserves enable this helicopter to perform a variety of aerial work duties, facilitated by the wide cabin's flat floors - which enable the loading of long and bulky goods - and the access provided through side and rear doors. Among the utility applications is the servicing of offshore wind farms, which are being located increasingly farther out to sea - requiring the hoisting and hover performance provided by the H145. Other utilizations include firefighting, the transfer of maritime pilots to arriving vessels and electronic newsgathering.
