The ACH135 is the corporate version of the twin-engine H135 helicopter previously known under Eurocopter EC135 designation. The development of the H135 started, as a German Messerschmitt-Bölkow-Blohm (MBB) design prior to the Eurocopter group formation in 1992. Eurocopter will become in 2014 Airbus Helicopter The H135 completed its first flight on February 15, 1994, prior to entering service in 1996.

The H135 offers a dual-engine selection and can be equipped with either two Pratt & Whitney Canada PW206B3 engines or with two Turbomeca Arrius 2B2plus, both are FADEC controlled. The H135 is also equipped with Airbus’ signature Fenestron shrouded tail rotor.

Designed primarily for the Emergency Medical Service (EMS), the H135 features a large EMS optimized cabin providing ample room for patient care. The H135 is a relatively quiet helicopter thanks largely to the refined main rotor blades with advanced geometrical tips and the fenestron anti-torque tail rotor system. The integrated anti-resonance isolation system (ARIS) further dampens induced rotor vibrations thereby enhancing, even more, the comfort.

The H135 flight deck is fitted with Helionix avionics, it features advanced intuitive software, a synthetic vision system, and a 4-axis autopilot system.
