Bombardier started the Learjet 45 program in 1989 with a goal to develop a jet that could cover short to medium range distance with a high speed. But they didn’t announce the program until 1992. This model was developed as a competitor in the super light business jet category. This jet introduced a completely new design language for Learjet models. For this reason the development took a long time to complete. Finally after 6 years of development, the first prototype was displayed on Oct 7, 1995. But it took another two full years to complete all the necessary tests and get the FAA certifications. Finally after a long awaited time, the first jet was delivered in mid 1998.
Specs & Performance
The Learjet 45 is powered by two Honeywell TFE731-20AR engines. These engines can produce 3500 lb thrust each providing these jets a max cruising speed of 460 Knots. It has an impressive climb rate of 4250 feet per minute and can reach up to 51000 feet. It can take off with a maximum weight of 20,500 lbs and can cover a range of 1968 NM. The range was slightly improved in the 45 XR variant. The cockpit of the Learjet 45 is equipped with the Honeywell Primus 1000 avionics system, offering advanced navigation and safety features. The glass cockpit setup features digital displays, providing pilots with clear, real-time data for safe and efficient flight management. The avionics suite includes GPS, weather radar, traffic alert systems, and flight management systems, allowing for improved situational awareness and reduced workload for pilots.
Cabin Design
The Learjet 45 cabin can accommodate up to 8 passengers in a double club configuration and two pilots. Though the cabin lacks enough headroom, it is quite longer than aircrafts of the same class and can hold up to six large suitcases. The cabin layout of the Learjet 45 is optimized for business travelers. It includes fold-out tables, allowing passengers to work or enjoy meals and a refreshment center, a galley area for drinks and light meals. Bombardier focused on soundproofing to reduce noise levels, making the cabin quieter than many other jets in its class.
Cabin Length | 19.75 feet |
Cabin Width | 5.12 feet |
Cabin Height | 4.92 feet |
Interesting Facts About the Bombardier Learjet 45
1. First All-New Learjet in Over 20 Years: The Learjet 45 was the first completely new design for the Learjet family in over two decades when it was launched. It was designed to compete directly with the Cessna Citation Excel and Hawker 800XP.
2. Design Collaboration: The development of the Learjet 45 involved collaboration with major aerospace companies like Gates and Honeywell to create cutting-edge technology for avionics, engines, and structural design.
3. Updated Version – Learjet 45XR: Bombardier later released the Learjet 45XR in 2004, which features more powerful engines (Honeywell TFE731-20BR) and an increased takeoff weight. The Learjet 45XR can carry heavier payloads, take off from shorter runways, and offers a faster climb rate than the original 45.
4. Strong Market Presence: The Learjet 45 and its variants have been widely used by charter operators, corporate flight departments, and individual owners due to their balance of performance, operational costs, and comfort.
5. Pioneering Glass Cockpit Technology: The Honeywell Primus 1000 avionics suite in the Learjet 45 was one of the first in business aviation to introduce full glass cockpit technology, paving the way for more advanced flight management systems in later Learjet models.
Learjet Legacy
The Bombardier Learjet 45 embodies the qualities that made the Learjet brand synonymous with speed and innovation. Its combination of high performance, advanced technology, and passenger comfort make it an excellent choice for private owners and business travelers seeking to maximize their time in the air. A total of 642 Learjet 45 aircraft were produced by Bombardier between its introduction in 1998 and the end of its production run in 2012. This includes both the Learjet 45 and the upgraded version, the Learjet 45XR. Despite discontinued production, Learjet 45 continues to hold its place as a top contender in the world of light and midsize business jets.
