[0002] The AW139 helicopter is a multi-role, medium-sized, twin-engine helicopter with a crash-resistant fuselage and a self-sealing and explosion-proof fuel system. Powered by two turboshaft engines, it offers robust performance suitable for high-temperature and high-altitude operations. Equipped with a 4-axis autopilot, a fully glass cockpit, and an integrated warning system, it significantly reduces pilot workload. It also supports night vision goggles (NVG) compatibility and operation in adverse weather conditions, enhancing mission reliability. Thanks to its superior performance, the AW139 helicopter is widely used in maritime commuting, firefighting, police operations, and military transport, with a large global presence, demonstrating its reliability.
