Overview and History of the Bombardier Learjet 31AER

The Bombardier Learjet 31AER falls into the light aircraft class.

The history of this iconic aircraft began with Learjet, a company known for creating high-performance light business jets.

The development and production of the Learjet 31AER took place from 1991 to 2003.

The 31 series is the last Learjet that can trace its design roots back to the original Learjet Model 23.

In 1987, Learjet was acquired by Bombardier, a Canadian multinational manufacturer, and the Learjet 31AER was one of the first aircraft to be developed post-acquisition.

This aircraft represented the growing ambitions of Bombardier, combining the speed and range capabilities of a large jet with the economical advantages of a light jet, making it an attractive option for many.

The Learjet 31AER not only upheld the reputation of the Learjet brand but also marked the beginning of Bombardier’s successful journey in the private aviation sector.

Performance of the Bombardier Learjet 31AER

Powered by two Honeywell TFE731-2 engines, the aircraft boasts an impressive thrust output of 7,000 lbs (3175 Kg).

The high-speed cruise is an impressive 451 knots (835 km/h), while the long-range cruise speed stands at 417 knots (772 km/h). 

The Learjet 31AER demonstrates its ability to reach soaring heights, with a maximum altitude of 51,000 feet (15,545 meters).

The aircraft’s range is a notable 1,911 nautical miles (3,539 kilometers), providing ample reach for most domestic and even some international routes.

The aircraft requires a take-off distance of 3,800 feet (1,158 meters) and a landing distance of 3,208 feet (978 meters). 

These performance figures represent the Learjet 31AER’s capabilities under ideal conditions.

However, actual range and ground performance can be affected by numerous factors, including weather conditions, passenger load, and fuel weight among others. 

Interior Layout and Features

The cabin dimensions provide ample space for passengers, with an interior width of 4 feet (1.2 meters), a length of 12.9 feet (3.9 meters), and a height of 4 feet (1.2 meters).

These dimensions ensure a comfortable environment for up to eight passengers, although a typical configuration would see six passengers enjoying the amenities. 

The cabin altitude capabilities are remarkable with a maximum cabin altitude of 7,800 feet (2,377 meters) and it’s able to maintain a sea-level cabin until reaching 25,700 feet (7,830 meters).

Having a low cabin altitude ensures a comfortable and pleasant flight experience, minimizing the effects of altitude changes on the body. 

The seating arrangement is a testament to the emphasis on both comfort and functionality.

The eight-place interior features soft-touch camel seating, including a belted side-facing seat in the lavatory area.

A highlight for travelers seeking privacy, the lavatory area boasts fully enclosed hard doors on either side. 

Cockpit and Avionics

The Learjet 31AER featured the Honeywell Primus 1000 Integrated Avionics system.

This system, renowned for its reliability and efficiency, provides pilots with comprehensive flight data, significantly enhancing their situational awareness.

The cockpit layout is designed with a dual-pilot setup, allowing for teamwork and shared responsibilities during flight operations.

Furthermore, the layout ensures that all essential controls and instruments are within easy reach of the pilots, allowing for swift and accurate responses during critical flight situations.

To enhance pilot comfort over long flights, the cockpit is ergonomically designed.

The seats are adjustable, providing ample legroom and support, ensuring that pilots maintain their focus on the task at hand. 

Charter Cost of the Bombardier Learjet 31AER

The estimated charter cost for a Bombardier Learjet 31AER within North America is approximately $3,200 per hour.

However, it’s essential to understand that this price isn’t fixed and the actual cost can fluctuate based on several factors.

These influencing factors can include but are not limited to, the distance of the flight, the duration of your stay, the time of year, and the departure and arrival locations. For instance, peak seasons may see an increase in demand, which could lead to higher prices.

Additionally, longer stays may necessitate crew accommodation, consequently affecting the overall cost. Therefore, while the Bombardier Learjet 31AER offers a high-class flight experience, it’s important to remember that the charter cost is subject to vary depending on various circumstances.

Purchase Price and Operating Costs

When new, this jet retailed at approximately $6.7 million.

However, the current market presents more affordable options with the average pre-owned price standing around $1.16 million.

Yet, as with any aircraft, ownership extends beyond the initial purchase.

The estimated annual operating costs, assuming an operation of 200 flight hours per year, come to around $672,000.

It’s crucial for potential owners to factor in these ongoing costs when considering a purchase, ensuring they are fully aware of the investment involved.
