Bombardier kicked off Europe’s largest business jet show in Geneva, Switzerland, today with an announcement of the Learjet 70 and Learjet 75 light business jets.
The new Learjet 70 and Learjet 75 aircraft build on legendary Learjet strengths and successes while leveraging Learjet 85 aircraft technology, The planes will replace the Learjet 40 and 45 models.
The jets will feature a new modern design interior, a next generation cabin management system, the Vision Flight Deck with a state-of-the-art avionics suite, superior aircraft performance and low operating costs. Entry-into-service is scheduled for the first half of 2013.
The two planes, which will be assembled in Wichita, will offer greater range, more speed, new interior styling, lighter weight, and, because they will have improved fuel efficiency, lower operating costs, said Ralph Acs, head of Bombardier’s Wichita Learjet plant.
The aircraft will have enhanced performance through an engine thrust increase with an improved Honeywell engine, offering improved takeoff field length performance over its predecessor. The new systems will also contribute to weight savings gain and the new canted winglets will improve aerodynamic efficiency. Overall, up to a nine per cent improvement in field performance under hot and high conditions and up to a four per cent improvement in fuel efficiency are expected.
The Learjet 70 and 75 will offer sportier performance than the Learjet 40XR and 45XR because they carry several hundred pounds less in avionics weight and are propelled by 700 lb. more thrust. The increased thrust will shorten takeoff field lengths to less than 4,500 ft. Runway performance long has been a sore point with Learjet 40-series operators. The -40AR engines used on Gulfstream G150 are rated at 4,420 lb. thrust to ISA+13C, thus the 3,850 lb. thrust -40BRs will have generous flat-rating margins for hot-and-high airport performance.
The new aircraft will climb directly to 45,000 and, once there, burn 4-5% less fuel than the aircraft they will replace because of the new winglets. (The -40BR engines have the same high altitude cruise thrust output and thrust specific fuel consumption as the -20BR turbofans on today’s Learjets).
Both aircraft will be able to carry at least 200 lb. more payload with maximum fuel and will be able to fly about 2,000 nm at long range cruise.
Based on the Learjet 85 aircraft interior design and technology, the Learjet 70 and Learjet 75 aircraft include: improved comfort and styling of the seats; cabin management system featuring individual touchscreen monitors with full audio and video control; LED lighting throughout the entire aircraft; a generous baggage suite and a spacious galley for optimized catering, work and storage space.
The advanced connectivity options of the Learjet 70 and Learjet 75 aircraft will ensure the highest levels of convenience.
Vision Flight Deck
A breakthrough in business aviation, the Vision Flight Deck is designed to deliver a completely new cockpit experience. By combining the best in technological advancements with superior design aesthetics, it provides pilots flying Bombardier’s Learjet 70 and Learjet 75 aircraft an unprecedented level of control and comfort. The Vision Flight Deck for Learjet 70 and Learjet 75 aircraft will feature the fully integrated Garmin G5000 digital avionics suite, designed with leading edge technology and one of the most intuitive crew interfaces available.
Upon entry into service, the aircraft will be supported by a maintenance program designed to allow customers to operate to a generous 600 flight hour fixed inspection interval at Bombardier’s growing worldwide Customer Services infrastructure. In addition, direct operating costs will be reduced as a result of performance efficiency gains.
Learjet 70 aircraft: The Learjet 70 aircraft will be able to achieve an exceptional range greater than 2,000 nautical miles at a cruise speed of Mach 0.75. It will connect Chicago-Sao Paulo and Toluca-Minneapolis non-stop(ii) with six passengers and two crew members.
Learjet 75 aircraft: With a maximum range greater than 2,000 nautical miles at cruise speeds up to Mach 0.75, the Learjet 75 aircraft will be able to fly four passengers and two crew members non-stop from Los Angeles to Toronto and Mumbai to Bangkok. Additionally, it will be able to handle a range close to 1,950 nautical miles with eight passengers.
