Development Purpose and History

The King Air series traces its origins to the Beechcraft Queen Air. The company developed the King Air in response to demand for a reliable, pressurized, twin-engine aircraft for business travel. The first model, the Model 90, made its maiden flight in 1963 and entered commercial service in 1964. Since then, the King Air has been continuously upgraded and produced in various models such as the King Air 90, King Air 200/250, and King Air 300/350/360 series. This extended production history has made it one of the most successful turboprop programs in general aviation history.
