The Airbus H-135 Helionix can offer the most safety and discretion in its class.The H135’s state-of-the-art cockpit with its new 4-axis autopilot provides the highest possible safety levels. The Helionix® avionics system designed by Airbus offers operators undisputed superiority for in-flight envelope protection, pilot assistance and situational awareness – resulting in unprecedented flight safety levels. The new Helionix® is also available on the H145, H175, and H160.Further contributing to operational safety are the rotorcraft’s high-set main rotor and the Fenestron® shrouded tail rotor. The H135’s latest performance improvement further aids flight safety, providing enhanced safety margins to the pilot and improved performance even in one engine inoperative (OEI) scenarios.As one of the quietest helicopters in its class, the H135’s sound footprint is markedly lower than that of other helicopters in the same category. This matters most to customers who regularly operate in or over cities and in densely populated areas, such as in corporate transport, emergency medical services and law enforcement.The H135 is allowed to fly in the United States’ Grand Canyon, which has one of the country’s most stringent noise limitations.
