The Bombardier Learjet 70 was the last of the Bombardier Learjet series along with the Learjet 75, receiving its FAA type certification in 2013. As the latest iteration of the Learjet series—and as an upgraded and enhanced version of the popular Learjet 40—the aircraft features improved avionics, revised winglets for better fuel-efficiency, and an advanced hydraulic system. According to Business Jet Traveler, the new technological advances help the Learjet 70 achieve the comfort and performance of a midsize jet with the operating costs of a light jet.
BOMBARDIER LEARJET 70 FEATURES
Interior
The Learjet 70’s seven-passenger cabin measures 17 feet 8 inches long, 5 feet 1 inch wide, and 4 feet 11 inches high for a total cabin volume of 363 cubic feet, making it one of the largest cabins in the light jet class. While the Lear 70 has the same cabin space of the Lear 40, the way the space is used has changed—seats and galleys have been redesigned, and passengers can utilize side-wall cutouts to store personal belongings. The jet also includes 65 cubic feet of baggage space that can be accessed both internally and externally.
The cabin features a forward-club formation that typically seats six passengers. It also includes touchscreen displays on the seats, high-definition monitors, and an iPod interface for the convenience of the passengers. Additional features include an aft bathroom with an optional toilet seat and executive tables.
Performance
The Learjet 70 is equipped with two Honeywell TFE731-40BR engines, which enable the aircraft to reach speeds of up to 464 kts, produce 3,850 pounds of thrust per engine, and have 10 percent more takeoff power than engines furnished on the 40 and 45. According to Business Jet Traveler, aided by new canted winglets, the engines provide faster climb times, better short-field performance, and improved high/hot capabilities. These engines are also four percent more fuel efficient than those on the Lear 40 and 45.
The Learjet 70 can cover up to 1,849 nautical miles with 6 passengers and NBAA IFR reserves, meaning it can fly passengers on routes like London to Moscow or Chicago to Vancouver in comfort and style.
Avionics
The Bombardier Learjet 70 utilizes the Garmin G5000 Vision flight deck, which includes widescreen displays, touchscreen controllers, and a synthetic vision system to assist with flight. The environment control system (ECS) that is installed in the Learjet 70 offers great control of the aircraft environment along with dual-zone control for cabin and cockpit. The cockpit also includes a digital audio system, datalink capabilities, and a surface awareness system that reduces the burden on the pilot.
