‘Best of Versatility and Comfort’

EC155 OverviewThe H155 (EC155 B1) is Airbus Helicopters’ high end 5-ton twin-engine helicopter. It is an enhanced version of the proven Dauphin family and boasts the most advanced technologies available. The H155 has a five-bladed Spheriflex® rotor head with an extremely low vibration level. Equipped with Airbus Helicopters’ famous Fenestron® tail rotor, the H155 performs with a noise level that falls 4.6 dB below ICAO level. It’s so quiet that passengers feel as if they are travelling in a business jet. The pilot’s workload is minimized by the aircraft’s quality Human Machine Interface, the most intuitive glass cockpit available, its single-pilot Instrument Flight Rules (IFR) capability and its unique Airbus Helicopters 4-axis autopilot. The first of its kind to be developed specifically for helicopters, this autopilot system was another Airbus Helicopters technological breakthrough and remains the best available in the world. Its outstanding functionality and user friendliness allow the pilot to fully concentrate on the mission during all flight phases over the full flight envelope, showcasing the H155’s excellent hover stability and its smooth high-speed flight. Other cutting edge technologies include Terrain Awareness Display, Enhanced Ground Proximity Warning System and satellite phone.

EC155 EngineThe H155 is equipped with two Safran Arriel 2C2 turbine engines, which are fitted with Full Authority Digital Engine Controls (FADEC) for fully automated One Engine Inoperative (OEI) safety. Thanks to its significant power, the H155 delivers a long range as well as the fastest cruising speed in its class. The cabin comfortably seats 12 passengers plus 2 pilots or, in its luxurious VIP configuration, 8 passengers and 2 pilots. Its exceptional roominess, comfort, speed, endurance and effectiveness make this aircraft a truly versatile helicopter ideally suited for the widest range of missions, including VIP and corporate transportation, long-haul offshore operations and inter-rig shuttle transportation, Emergency Medical Services (EMS), Search And Rescue (SAR), Police, Special Forces and other governmental roles.
