Overview
H145 D3
In 2020, a new innovative version of the H145 entered service equipped with a five-bladed main rotor. This new H145 embodies a major customer expectation: the ability to operate an aircraft with a great useful load. On that point, the H145 is over-performing, and surpassing all the competitors in its class. The latest version of Airbus’ H145 family has an additional 150 kg useful load, leading to the best useful load to maximum takeoff weight ratio for a light twin helicopter.
The new H145’s D-value (the largest overall dimension when rotors are turning) is further reduced, enabling the aircraft to land in even more confined areas. This agility makes the H145 the best choice for challenging EMS and public service missions.
Airbus has set a new standard in smoothness and flight comfort with its bearingless and hingeless five-blade main rotor. The strain on crews has been reduced considerably – improving overall mission efficiency. This innovation builds on the rotor’s simplified maintenance, increasing the availability rate – which is already remarkable on the H145.
‘The H145 is perfectly suited for the most demanding multi-purpose mission requirements’
The H145 (EC145 T2), the newest 4-ton class twin engine, multi-purpose helicopter in the Airbus Helicopters product range, is the latest evolution of the EC145/BK117 family. This family of aircraft has seen more than 800 deliveries worldwide and has accumulated more than 3 million flight hours.
Extended Mission Capabilities
Sharing many basic features with the EC145, the H145 will be able to be equipped with the same optional equipment to carry out missions such as EMS, Law Enforcement, SAR, Business Aviation, oil and gas and utility.
The H145 comes with a 4-axis autopilot, optimizing the capabilities of the aircraft for over-water day and night SAR missions. This innovative autopilot, was developed specifically for helicopters, is already available and in operation on the H155, H175 and H225.

‘The Ultimate Multi-role Helicopter’
In operations on land and at sea, the H145 is at the top of its class in the medium-sized, twin-engine helicopter category. With up to 12 seats for pilots and passengers, this multi-mission helicopter combines Airbus Helicopters’ latest developments such as an advanced cockpit design, avionics and a sophisticated electrical system. The H145 offers a proven hingeless rotor system with a monolithic titanium hub and enhanced rotor blades, which ensure low noise and vibration levels.
The H145 is equipped with two Safran Arriel 1E2 engines which provide outstanding performance and vital power reserves even in one engine- inoperative (OEI) scenarios. 
The H145’s twin-engine reliability is enhanced by a completely separate fuel system, a tandem hydraulic system, a dual electrical system and redundant lubrication for the main transmission. Further built-in safety aspects include energy-absorbing fuselage, seats and crash-resistant fuel cells. In addition, the H145 allows for Category A operations up to performance class 1 according to JAR-OPS 3.
Compared to other helicopters in its class, the H145 offers a significantly larger cabin featuring excellent outside visibility for pilots, crew and passengers, a roomy cabin with no partitions, center or door
posts and unrivaled side and rear loading capability.

The H145 combines Airbus Helicopters’ breakthrough technologies, including an advanced cockpit design, modern avionics, 4-axis autopilot and a Fenestron® tail rotor, with the rugged and proven designs of the BK117 family, such as the main rotor system. Thanks to its outstanding roomy and versatile cabin, this aircraft can accommodate up to 12 seats and can be configured for either one or two pilots.
each controlled by a dual channel Full Authority Digital Engine Control (FADEC), which, in combination with the aircraft’s lifting system, provide outstanding All Engine Operative (AEO) performance. The One Engine Inoperative (OEI) performance of this new aircraft version have been significantly improved. The H145 is capable of Category A operations up to Class 1 and Class 2 performance, according to EASA OPS.
The H145 is equipped with two powerful and reliable Safran Arriel 1E2 engines which provide outstanding performance and vital power reserves in OEI scenarios. The use of the variable rotor speed and torque matching system (VARTOMS), known from the predecessor model BK117 C- 1, enhances overall flying comfort, and makes the H145 the quietest helicopter in its class at 6.7 decibels below ICAO noise level.
The H145 offers unmatched visibility and an incredibly discrete noise level—6.7 dbA below ICAO limits—for effective EMS operations. The state-of the-art, IFR-equipped glass cockpit avionics display is compatible with night-vision goggles (NVGs), so the H145 is fully functional both night and day. The H145 is also particularly adapted to primary EMS missions and flying intensive care units. Its unobstructed cabin has room for two stretchers, three seated persons and all the necessary medical equipment. Its rear clamshell doors allow easy straight-in loading of the stretchers, and extra-wide side doors provide effortless access for attendants and crew. Different configurations of the EMS interior – each tailored
The H145 ensures exceptional reliability and performance parameters in extreme weather conditions. It is equipped with two powerful Safran Arriel 1E2 turbine that provide an optimal level of safety in one-engine-inoperative (OEI) scenarios. Furthermore, the high-set main rotor and tail rotor improve safety on the platform. In the oil and gas configuration, the H145 offers comfortable seating for up to nine passengers plus a pilot. Passengers can easily access the cabin via extra-wide sliding doors on either side or clamshell doors at the back.
The H145 is the best value solution for utility missions. The H145’s unobstructed main cabin is easily reconfigurable to maximize mission flexibility and the helicopter’s sliding side and rear clamshell doors optimize access to the cabin. The high-set main and tail rotor provide unparalleled safety and access, allowing the loading and unloading of passengers or cargo while the rotors are running. Extensive use of new, lightweight manufacturing materials and extensive system modularity simplifies maintenance, reducing lifetime ownership costs and logistic requirements. The H145 was selected by the U.S. Army as new multi-mission Light Utility Helicopter (LUH), called the UH-72A Lakota.
In order to meet the continuously growing responsibilities and tasks of public service missions, the H145 can be equipped with the most modern and experienced police equipment on the market. Fast and reliable, the H145 can rapidly transport up to 11 officers to the scene of an accident. The H145 is fully NVG-compatible.
The H145 is the only helicopter in its category to combine a roomy cabin and excellent window visibility, providing exceptional passenger comfort. This aircraft offers high rotor clearance and large luggage clamshell doors, and extra-thick interior insulation and special flooring that damps out any residual vibration. The H145, with its sporty yet elegant atmosphere, invites passengers onboard via large sliding doors that provide easy cabin access. Inside, passengers discover the stylish comfort of the cabin and its various amenities while they admire the view. With its low noise and vibration levels, corporate and private helicopter users alike can work or relax in the living space.
