Airbus H125

The Airbus H125, known for most of its production life under its earlier designation as the Eurocopter AS350 Ecureuil, is a French single-engine light helicopter built originally by Aerospatiale and later by Eurocopter and Airbus Helicopters, entering service in 1977 and remaining in continuous production for decades since. Built as a versatile utility helicopter capable of operating reliably at high altitude and in hot conditions where engine performance is most challenged, the H125 has been widely adopted for mountain rescue, aerial firefighting, agricultural spraying, law enforcement and tourism flights, including operations at extreme altitudes such as scientific support flights near Mount Everest. Its single-engine simplicity and strong power-to-weight ratio have made it one of the best-selling light helicopters in aviation history.
