These models feature new avionics, winglets, and powerful engines that use less fuel. [3]

The Learjet 40/45 light jet is updated with touchscreen-controlled Garmin G5000 avionics and a modern interior. [4] The combination of aerodynamic improvements, which lowered the design's drag by 2%, and 200 lbs less weight in the nose section resulted in an increased range of 4%. [5]

The canted winglet design was incorporated from the Bombardier Global 7500/8000. [6]

Both variants are powered by 3,850 lbf (17.1 kN) Honeywell TFE731-40BR turbofans with thrust reversers, have a MTOW of 21,500 lb (9,800 kg) and a fuel capacity of 6,062 lb (2,750 kg) for a maximum range of 2,050 nmi (3,800 km) with four passengers. Typical cruise is Mach .76 and high-speed cruise is Mach .79, the ceiling is FL510 where the cabin altitude is 8,000 ft (2,400 m). Their flat-floor cabin width is 4 ft 11 in by 5 ft 1 in (1.50 by 1.55 m) high, the Learjet 70's seven-seat cabin length is 17 ft 8 in and 19 ft 10 in (5.38 and 6.05 m) for the nine-seat, double-club Learjet 75. The forward galley facing the entry door is isolated by a pocket door from the seating area with a Lufthansa Technik cabin management, and the aft lavatory has a belted seat. The 50 cu ft (1.4 m3) external baggage hold is heated but not pressurized. [4]

At FL410, ISA + 3 °C (5 °F) and Mach .78 for 462 kn (856 km/h), its hourly fuel burn is 1,000 lb (450 kg) and 1,400 lb (640 kg) at Mach .80.


Development

Two of the planned five flight test aircraft, a modified Learjet 40XR and Learjet 45XR, had flown by July 2012. [7]

The Learjet 75 received its type certificate from the FAA on 14 November 2013. [8] Deliveries began shortly thereafter. [9] [a] This delay in certification caused order cancellations, and Bombardier's overall deliveries fell below expectations. [11] By 2015, the unit cost of the Learjet 70 was US$11.3 million, and US$13.8 million for the Learjet 75. [12] By 2016, production of Learjet 70 had been temporarily discontinued due to lack of orders (with Learjet 75 still being produced at that time). [13]

The 100th Learjet 75 was delivered in June 2017. [14]

By January 2019, Bombardier had delivered 132 Learjet 40/40XRs, 454 45/45XRs, and nearly 130 70/75s, including 24 in 2016 and 14 in 2017. [4] In June, Bombardier launched the sub-$10 million Learjet 75 Liberty to compete with the Cessna CitationJet and Embraer Phenom 300 from 2020, with six seats down from eight, no standard APU or lavatory sink, but still Part 25 and not FAR Part 23 certified, with a maximum payload of 2,910 lb (1,320 kg) and a range of 2,080 nmi (3,850 km). [15]

Bombardier announced the end of the production of Learjet aircraft by the end of 2021. [16] The final Learjet 75 was manufactured in January 2022. [17] As Bombardier focuses on its larger Challenger and Global jets, it was delivered on 28 March 2022. [18]

The Embraer EMB-505 Phenom 300 is a light business jet designed and produced by the Brazilian aerospace manufacturer Embraer. Certified for single-pilot operations, it can carry up to 11 occupants. Work on the Phenom 300 started in response to customer demands for a larger business aircraft than the Phenom 100, a very light jet. While the design team originally intended for the aircraft to be a straightforward stretched derivative of the Phenom 100, a clean sheet approach was later adopted. The Phenom 300 featured more powerful engines, the addition of spoiler and winglets, along with an elongated cabin to accommodate more passengers. Several features, from its cabin and interior design to its landing gear and structure, can be traced back to the Phenom 100.
