Bell 407 (FADEC engine)

The Bell 407 is a multipurpose civil utility helicopter. It uses the four-blade, soft-in-plane rotor with composite hub developed for the United States Army, instead of the common two-blade. It is used for corporate and offshore transport, as an air ambulance, by law enforcement, and for electronic news gathering and motion picture filming. The Bell 407 blends reliability, speed, performance, and maneuverability with a cabin configurable for a variety of purposes and payloads. It provides a very quiet and smooth ride in all weather conditions, a clear and important reason for its popularity. Its turbine FADEC engine delivers exceptional hot and high altitude performance with the ability to cruise at 140 knots (259 km/hr). FADEC stands for full authority digital engine, and is characterized by the digital computer that is contained in the engine, optimizing it for peak engine performance, better fuel efficiency, and a higher safety rating.
