The medium range Learjet 35A, created as a replacement for the Learjet 35, represented Learjet’s first clean sheet design since its original Learjet 23 came to market.
Launched in 1992, the company took full advantage of the opportunity to update and enhance its iconic jet, making the Learjet 35A the first business aircraft designed entirely on computer
rather than paper. The FAA strengthened its standards for anti-ice systems during the model 35A’s development, and the aircraft came to market with the most advanced anti-ice system of any
light or mid-sized jet.
Learjet 35A Design
Bombardier also convened numerous customer focus groups during the design phase, ensuring the cabin would be every bit as comfortable as the aircraft is capable.
First flight lifted off in 1995, FAA certification was awarded in 1997 and the model entered service in January 1998. In keeping with customer input, the Learjet 35A’s interior is
designed to offer the most usable passenger space possible for the volume, offering more legroom, seat width and galley storage area than the model 35. In fact, the model 35A’s
flat-floor cabin was the first design element, and the rest of the airplane was built around it.
Learjet 35A Cabin
The cabin is arranged in a double-club configuration with eight reclining seats, with both in-base and floor tracking, and slide and swivel motions. Details like fold-down work tables,
a two-zone temperature control system and low noise levels (the cabin never exceeds 72 dB) ensures the cabin is both functional and comfortable.
Learjet 35A Engines
The aircraft is powered by two FADEC-controlled Honeywell TFE731-20AR engines, each delivering 3,500 lbs. of thrust. The -20AR engine variant was developed specifically for this airframe.
With winglets improving its performance, the Learjet 35A has a top cruise speed of more than 530 mph and a 51,000-foot service ceiling, enabling it to cruise over almost any weather.
Learjet 35A Interior
The cockpit features a four-screen Honeywell Primus 1000 EFIS avionics suite with a built-in avionics and engine diagnostic system that records anomalies digitally,
allowing the data to be downloaded and speeding up maintenance and troubleshooting. This last capability adds to one of the aircraft’s most popular aspects among owners:
its low direct operating costs, which are more on a par with light jets than with other jets in the midsize category. Indeed, with 410 cubic feet of cabin space, the Learjet 35A
feels like a large midsize jet, comparable to a Hawker 800XP or Citation VII. With high performance, low operating cost and surprisingly roomy cabin, the
Learjet 35A remains one of the best values in the midsize jet category.
