About the IAI 1124 Westwind

The Israel Aircraft Industries 1124A Westwind II is a twin-engine business jet that emerged in the early 1980s as an evolution of the original Westwind design, itself derived from the Aero Commander 1121 Jet Commander. IAI refined the type with improved Garrett TFE731 turbofans, upgraded avionics, and a stretched fuselage, creating a capable mid-size corporate transport that could carry eight to ten passengers across transcontinental ranges. The Westwind II found a niche among charter operators, air ambulance services, and government agencies seeking a reliable platform with good short-field performance and relatively modest operating costs compared to contemporary Learjets and Cessna Citations.

What distinguishes the 1124A is its rugged Israeli engineering heritage and versatility in secondary roles. Beyond corporate shuttles, Westwind IIs have served as medevac platforms, cargo feeders, and special-mission aircraft for reconnaissance and calibration work. The type's high-mounted engines and sturdy landing gear allow operations from shorter runways and less-developed airfields, a trait valued by operators in remote regions. Maximum cruise speed approaches 470 knots, with a service ceiling of 45,000 feet and a range of roughly 2,400 nautical miles with reserves, competitive figures for its era, though modest by today's ultra-long-range business jet standards.

Production ended in the late 1980s after approximately 36 Westwind IIs were built, making it a relatively rare sight compared to mass-produced business jets. Most surviving airframes now serve specialized operators rather than corporate flight departments, with air ambulance providers particularly drawn to the spacious cabin and reliable twin-jet redundancy. The type remains certified and supported, though parts availability and maintenance expertise have become more concentrated as the fleet ages.
