The IAI Westwind is a business jet initially produced by Aero Commander as the 1121 Jet Commander. Powered by twin GE CJ610 turbojets, it first flew on January 27, 1963, and received its type certification on November 4, 1964, before the first delivery. The program was bought by Israel Aircraft Industries (IAI) in 1968, which stretched it slightly into the 1123 Westwind, and then re-engined it with Garrett TFE731 turbofans into the 1124 Westwind. The 16,800–23,500 lb (7.6–10.7 t) MTOW aircraft can carry up to 8 or 10 passengers, and 442 were produced until 1987

The Westwind was originally designed in the United States by Aero Commander as a development of its twin-propeller namesake aircraft, first flying on January 27, 1963, as the Aero Commander 1121 Jet Commander.[2] After successful testing, the aircraft was put into series production with deliveries to customers beginning in early 1965

Design

The Jet Commander/Westwind was of broadly conventional business jet arrangement, with two engines mounted in nacelles carried on the rear fuselage, but the wings were mounted halfway up the fuselage instead of the typical low-wing arrangement of aircraft in this class.

At FL310 and Mach 0.74 (436 kn; 808 km/h), the 1124 burns 1,600 lb (730 kg) per hour, and 1,200 lb (540 kg) at Mach 0.7 (413 kn; 764 km/h).

The 1122 Type Certificate was cancelled, the two airplanes manufactured have been converted to model 1123. The 1124N Sea Scan is a maritime surveillance aircraft, and the 1124 was renamed Westwind I after the introduction of the 1124A Westwind II
