In the competitive world of mid-sized business jets, few aircraft manage to carve out a legacy of both rugged reliability and surprising comfort. The Westwind II, a product of Israel Aircraft Industries (IAI), is one such machine. While its production run concluded decades ago, this twin-turbofan aircraft remains a respected and highly capable workhorse, a testament to thoughtful design and continuous refinement.

A Heritage Forged in the Golden Age of Business Aviation

The story of the Westwind II is one of evolution. Its lineage traces back to the 1960s with the Aero Commander 1121 Jet Commander, one of the earliest purpose-built business jets. When IAI acquired the manufacturing rights in 1968, they embarked on a journey of continuous improvement, first producing the Westwind 1123 and 1124 models.

The definitive upgrade arrived with the IAI 1124A Westwind II, which entered production in 1980. This was not merely a cosmetic refresh; it was a comprehensive aerodynamic and systems overhaul designed to keep the aircraft competitive against newer rivals like the Learjet 55 and the Citation III.

The Defining Feature: Whitcomb Winglets

The most visually striking and functionally significant change that defined the Westwind II was the addition of the distinctive Whitcomb winglets. Mounted atop the aircraft's signature wingtip fuel tanks, these upward-canted extensions were more than just a stylish flourish. They were a cutting-edge aerodynamic solution that significantly reduced drag, leading to improved fuel efficiency, better high-altitude performance, and an increase in effective range. This feature, which is now commonplace on modern airliners, gave the Westwind II a significant advantage in its era.

Beyond the winglets, the Westwind II incorporated other key enhancements, including an updated Collins Pro Line avionics suite and a redesigned wing with drooped leading edges and double-slotted flaps. These changes collectively improved the aircraft's handling characteristics and short-field performance, cementing its reputation as a pilot's aircraft.

Performance, Practicality, and the Pilot's Perspective

The Westwind II is powered by two Garrett TFE731-3 turbofan engines, providing a powerful and reliable thrust. This configuration allows the aircraft to achieve a maximum cruising speed of approximately 455 knots and a range of up to 2,700 nautical miles, depending on the load and configuration. This range capability made it a highly practical choice for transcontinental flights within the United States or for connecting major European cities.

What truly sets the Westwind II apart is its reputation for ruggedness and reliability. It was built to withstand demanding operational environments, a trait that has made it popular in utility, air ambulance, and military roles around the world. For operators, this translates to a durable airframe and predictable maintenance, factors that contribute significantly to its enduring value in the pre-owned market.

Cabin Comfort: A Mid-Size Surprise

Despite its performance focus, the Westwind II offers a surprisingly comfortable cabin for a jet of its generation. Most configurations comfortably seat seven to eight passengers, with a maximum capacity for up to ten. The cabin layout is typically arranged with a four-place club section and a three-place side-facing divan.

A key differentiator from some of its contemporaries is the cabin's generous dimensions, particularly the full-width lavatory and the ample baggage space accessible in flight. This attention to passenger comfort, combined with its impressive range, made the Westwind II a favorite for business travelers who valued both speed and a comfortable environment for long-duration flights.

The Westwind II's Lasting Impact

The production of the Westwind II concluded in 1987, with over 150 units of the "II" variant delivered. Today, the aircraft continues to be a strong contender in the value-oriented mid-size jet category. Its combination of robust construction, excellent range, and relatively low operating costs for its class ensures that it remains a fixture in the skies.

For buyers seeking a classic jet with a proven track record, the Westwind II offers a compelling blend of history, performance, and practicality. It is a true testament to the engineering prowess of IAI and a definitive chapter in the history of business aviation.
