Beechcraft King Air history, performance and specifications

The Beech King Air is the world's most popular turboprop aircraft. Beech Aircraft Corporation developed the King Air in 1964 as a compromise between piston-engine and jet aircraft and the design quickly found success. The King Air can fly farther and higher than piston-engine aircraft, and, unlike many jets, it can land on the short runways of most small airports. With the three different models, including the C90B, still in production in 2001, this aircraft remains the primary business aircraft for small to mid-size companies, and it is an integral part of the flight inventories of many larger corporations.

Since its incorporation in 1932, Beech Aircraft was a successful builder of civil and military aircraft. After Walter Beech's death in 1950, his wife and co-founder, Olive Ann, became president and chairman of Beech and she continued the profitable aircraft production lines, while also diversifying into other aerospace endeavours. In 1959, Beech Aircraft introduced the Model 65 Queen Air to fill the gap between the six-seat twin-Bonanza, a derivative of the single-engine Bonanza introduced in 1947, and the Super 18, a deluxe version of the classic Beech 18. The Queen Air featured the low-wing, all-metal, tricycle design typical of Beech's post-war aircraft, carried seven to nine passengers, and featured two horizontally-opposed 340-hp Lycoming engines. Subsequent improvements included a swept tail and a pressurized fuselage, but when turboprop engines were added to a Queen Air 88 in 1964, it was re-designated the King Air 90.

In August 1963, Beech Aircraft announced the King Air design to meet the requirements of executive and corporate business travel for six to nine passengers, using turboprop engines to bridge the gap between piston-power and jet aircraft. The first King Air, powered by Pratt & Whitney Canada PT6A-6 engines, flew on January 20, 1964 and, after the prototype completed a 230-hour test program, the design received its type certificate on May 27, 1964. The first production aircraft deliveries began in late 1964.

The design was a low-wing cantilever monoplane of aluminium construction with retractable tricycle landing gear. To improve its utility and safety in changing flight conditions, standard equipment, that had been optional on the Queen Air, included de-icing boots on the leading edges of the wings, fin, and tailplane. Flight instruments allowed for all-weather capabilities and various communications and navigation packages included autopilot, radio, and radar systems. The Model 90 had two seats in the cockpit and four reclining passenger seats facing each other in the cabin, with options for a two or three-place couch for passengers. Air conditioning and soundproofing also improved passenger comfort in the cabin. Two 500-hp P&W Canada PT6A-6 turboprop engines with three-blade Hartzell propellers gave the King Air a top ceiling of 27,400 feet and a range of 1,565 miles at 270 mph. Piston-powered aircraft could not match this performance while emerging jet aircraft of the 1960s used turbojet engines that were high-priced, noisy, and had high fuel consumption.

Rather than investing in a completely new and expensive technology, Beech built a vastly improved and marketable business aircraft from its existing production line. After the King Air's initial success, Beech concentrated on continuous upgrades to appeal to a range of executive and corporate needs. Sophisticated electronics packages, increased cabin space, and finer interior amenities in Models 90, 100, 200, 300, and 350 provided comfortable working and transport environments for business travellers. Newer models are longer and sport T-tails, but the basic configuration remains the same and continues to appeal as a new or previously owned medium-range aircraft. In addition to the airframe, the Pratt & Whitney Canada PT6A turboprop engine family consistently provides a high level of performance and reliability. Nearly 40 years since its introduction, the King Air series is still the king of the turboprops and fills a significant niche in the business aviation marketplace.
