Learjet 35 & 36
The Learjet 35 is known, above all, for its range. It can fly 1,400 miles nonstop. That means direct flights from Los Angeles to New York , from Seattle to Detroit – or pretty much anywhere. The Learjet 35 offers more than range: it has good handling characteristics, a low fuel burn, and fast cruise speeds as well.
A maximum of eight passengers can travel in the Learjet 35’s cabin. It is 12.9 feet long, 4.9 feet wide, and 4.3 feet high. There are 40 cubic feet of baggage space, enough to hold about eight standard-sized suitcases.
The real strength of the Learjet 35 is its range, takeoff, and cruise capabilities. Two Honeywell TFE731-2-2B engines provide 3,500 pounds of thrust, allowing the Lear 35 to take off in 4,972 feet. The maximum take off weight is pretty high as well at 18,300 pounds.
Components of these engines have been used on much higher-performing jets. Their pressure compressors were taken from the Garret 660-series engine, which is used on 747s. Their turbine components come from DC-10s, and the high-pressure impellers are a modified version of the one used in the TPE 331 and T76 engines.
The Learjet 35 is has a relatively long range for a private jet, and can cruise at speeds as high as 451 ktas, or 424 ktas with four passengers. Fuel consumption is excellent: the 31A burns only 177 pounds of fuel per hour. For comparison’s sake, that’s 14 pounds fewer than the Hawker 400XP and 64 pounds fewer than the Citation VI.
A few other details make the Learjet 35 a popular private jet. First of all, it meets FAR part 36 noise standards, making it a kind of “good neighbor” at airports. Furthermore, the avionics system is completely redesigned from previous models, giving pilots an uncluttered control panel that is easy to work with. Pilots have also commented on its agility and excellent performance capabilities.
The Learjet 35 has received some interesting honors since the first serial number rolled off the line. It was selected for use as a military jet, where it now operates with the name C-21. It was the first private jet to land at Denver International Airport when their new runway opened, and it seems to be a favorite among celebrities.
The Learjet Model 35 and Model 36 are a series of multi-role business jets and military transports (designated by the U.S. Air Force as C-21A). Powered by two Garrett TFE731-2 turbofan engines, the 35 and 36 require a crew of two and can carry from six to eight passengers. With a speed of 440 knots, the 35 and 36 are among the fastest business jets. The 35 can seat seven passengers, with an eighth passenger on the jumpseat immediately behind the copilot. The Model 36 is a longer range version, and thus has two fewer seats in order to make room for more fuel.
The turbofans are pod-mounted on the sides of the rear fuselage. The slightly swept wings have hydraulically actuated, single-slotted flaps. The aircraft has a retractable tricycle landing gear, single steerable nose gear and multiple-disc hydraulic brakes. The wingtip fuel tanks distinguish the design from other aircraft having similar functions.
The safety and operational capabilities of the 35 and 36 are increased by the autopilot, color weather radar and tactical air navigation system, as well as high frequency, very high frequency and ultra high frequency radios. The aircraft has a flight crew of two and may be flown from either cockpit seat. It is equipped with an automatic navigation system to enhance crew efficiency. When EFIS-equipped, four cathode ray tubes display essential information to the pilots.
