Overview & History

The IAI Westwind 1 is a product of Israel Aerospace Industries (IAI) and is the predecessor to 1124A Westwind 2.

The Westwind 1 prototype first flew on January 27, 1963.

This medium size corporate jet, produced between 1979 and 1987, exhibits the commitment of IAI to deliver high-performance and luxury in one package.

The development of the Westwind 1 was driven by the need to create an aircraft that offers both comfort and performance. The design process was meticulous, with each detail being thoughtfully curated to ensure that the aircraft meets the needs of the discerning traveler.

The result is an aircraft that not only delivers superior speed and range but also provides a spacious and luxurious cabin, setting new standards in private aviation. The Westwind 1 is more than just an aircraft; it’s a testament to IAI’s vision and innovation in the world of private jets.

From its inception to its final production, the Westwind 1’s history is a captivating story of technological triumph and timeless elegance.

Performance of the IAI 1124 Westwind

Let’s take a look at the performance for the Westwind.

The IAI Westwind 1 is powered by two Honeywell TFE731-3D-1G turbofan engines (originally Garrett TFE731), each producing a thrust output of 7,400 lbs (3356.6 kg).

These two engines enable the Westwind 1 to reach a high-speed cruise of 424 knots (785.2 km/h) and a long-range cruise speed of 400 knots (740.8 km/h).

In terms of altitude, the aircraft can achieve a maximum height of 45,000 feet (13,716 meters), ensuring smooth and efficient travel above most weather conditions.

The Westwind 1 also boasts a commendable range of 2,750 nautical miles (5,093 km), which allows for considerable distance coverage. However, considerations such as wind, temperature, weight, and aircraft configuration can influence this.

The aircraft requires a take-off distance of 5,265 feet (1,604 meters) and a landing distance of 2,864 feet (873 meters), making it adept at operating in smaller airports with shorter runways.

These performance figures represent the best-case scenario, and actual performance can vary depending on numerous factors such as atmospheric conditions, flight rules, and specific mission requirements. This ensures flexibility in flight planning and operations, tailored to the needs of each flight. 

Interior & Comfort

The cabin measures 4.8 feet (1.5 meters) in width, 15.5 feet (4.7 meters) in length, and has a height of 4.9 feet (1.5 meters). The cabin dimensions offer substantial space for passenger movement and relaxation. 

The business jet is designed to accommodate a maximum of 10 passengers.

However, a typical configuration comfortably seats 7 passengers, ensuring each individual has ample legroom and personal space during the journey. This configuration is an ideal blend of comfort and efficiency, allowing passengers to relax or work in a peaceful environment.

Notably, the IAI Westwind 1 also provides excellent cabin altitude performance. It maintains a sea-level cabin altitude until 23,000 feet (7,010 meters), ensuring a comfortable and pleasant environment for passengers.

Beyond this, the aircraft achieves a maximum cabin altitude of 8,000 feet (2,438 meters). This helps in reducing fatigue and maintaining the overall well-being of passengers throughout the flight.

The interior layout typically includes plush seating, storage compartments, and a well-equipped galley. Each element of the cabin’s interior is carefully crafted, offering a perfect blend of aesthetics, comfort, and functional design. 

Westwind 1 Cockpit

The cockpit features a dual-control system, allowing either pilot to take control of the aircraft.

This setup contributes to the safety and reliability of the aircraft, ensuring that control can be smoothly transitioned between pilots if necessary. The cockpit’s instrument panel is clearly organized, enabling pilots to monitor and control the aircraft’s systems with ease. 

In terms of technology, the IAI Westwind 1 is outfitted with state-of-the-art navigational equipment, including GPS and autopilot systems. These systems aid in accurate navigation, ensuring precise flight paths and reducing pilot workload.

Hourly Charter Rate

Chartering the IAI Westwind 1 is estimated at a rate of approximately $3,100 per hour in North America.

However, it’s important to understand that this figure can fluctuate based on a variety of factors. The final cost is typically influenced by elements such as the trip’s duration and distance, the time of year, and the current market conditions.

Other considerations might include additional requirements like onboard catering or ground transportation services.

Purchase and Operating Costs

When it was initially introduced to the market, the IAI Westwind 1 carried a price tag of approximately $3.8 million.

Today, a pre-owned Westwind 1 can be acquired for an average price of around $300,000, a significantly more attainable figure for many private jet buyers. Of course, ownership costs extend beyond the initial purchase price. 

Operating the Westwind 1 for around 200 hours per year incurs an estimated annual ownership cost of nearly $1 million. This figure encompasses a multitude of expenses, including fuel, maintenance, insurance, and more. Thus, when considering the purchase of a Westwind 1, it’s crucial to not only factor in the purchase price but also the ongoing operational expenses.

Understanding these costs in their entirety is key to making an informed decision.
