L-188, this rumor comes from a PC-12 operator up here, namely me. Heck, if Learjet can do it, why cant we. No extra charges for P3D. Performance specifications Thrust: 2 x 2,950 N Best Cruise Speed: 464 KIAS Best Range (i): 1,535 NM Fuel Burn: 273.2 GPH Stall Speed: 91 KIAS Rate of climb: 6,050 FPM Ceiling: 45,000 FT Takeoff distance: 5,186 FT Landing distance: 2,703 FT Weights Gross Weight: 15,000 LBS Empty Weight: 7,640 Airliners.net is the leading community for discovering and sharing high-quality aviation photography. Here is a recent price break down from Business and Corporate Aviation magazine. Two disc-type indicators are flush mounted under the left engine. The best glide distance with engines windmilling is obtained with a clean airplane configuration and with a glide speed of 160 to 170 knots. The time required to accelerate from idle to 100% RPM is approximately four seconds. Hopefully Flysimware will tweak this accordingly. A new cuff was designed to accelerate the air movement in this area that smoothed the flow between the engine nacelle and the wings trailing edge. Intersting. At this speed, the Learjet 25 glides approximately 26 nautical miles for each 10000 feet of altitude loss. It's got a stick shaker unit that forces the nose down if you get it too slow, pulls it up if you get too fast, This method was first used by Lionheart Creations in their Lear 24B add on and makes great use of the limited panel space. With a cruising speed of approximately Mach 0.76, passengers reach their destination in good time. By 2018, 1970s Learjet 25s were sold for under $200,000. Simply put, a shorter cabin to make room for more fuel. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 If enough folks who buys this add-on and also wishes it included the Fuel Jettison feature would simply ask that it be put on the list for any possible updates, changes, fixes, etc. The Go Around feature is especially well done, be sure to learn more about it. You can find a series of great screenshots of the XP GLJ 25 SE in flight in our screenshot forum. A jet pump installed in each tip tank transfers fuel into the wing tanks. 1,000 nm fuel burn for the Model 25D is 3,920 pounds, compared to 2,530 pounds for the Model 35/36, and 2,480 for the Model 31A. But, the standup and walk around Learjet cabin would arrive at a later date with the 40 and 60 series. These were contributed by none other than Ryan Butterworth in his mini-review as it is being called and a few others fans of the Classic GLJ25. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. Improved version with greater fuel capacity. They can walk you thru the service cost aspect of a Lear. Ouch. At 6000 feet elevation, 50 degrees Fahrenheit and with an average load of 5 passengers, the Learjet 25B will require approximately 8000 feet of runway. The Sun visors do more than flip up or down. This one got interrupted a couple of times and I feel guilty that it took me so long to finally complete the review. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. That all makes a big difference as to practicality, purpose, and just plain thrill factor! Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. Talking about those small fuselage Learjets, take a look at this comparison of a Lear Model 25 fuselage diameter compared to the Learstar 600 design. When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. The CJ610-6 engines fitted to the Learjet 25 have very low inertia and accelerate rapidly. Rest assured, the productionl ine is still rolling right along. Photo: A Gates Learjet showing enormous size of fanjet engines. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. Just use the Find function and locate the values in the aircraft.cfg file and make your changes. It will also cost less to buy, and you won't have to pay MSP, but you will have to assume it will have only minimal residual value. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. Not much, but . 47 Our Model selected for this review is in the center. The conventional airspeed scale is calibrated in knots and the Mach scale is calibrated in percentage of Mach and connected to an aneroid that moves the scale to compensate for changes in pressure altitude. The flaps are hydraulically operated. Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. 2023 MOTORSPORT NETWORK. This pales in total numbers when compared to the Cessna Citation family of business jets that is more than 6,000 and counting. This valve controlls * All weight in excess of the Max ZFW must be fuel in the - 25 C In standby, it powers just the gyro The trim check very important on the Lear Jet, as the trim system The system operates the landing History. The Learjet 25 is similar to the Model 24 but is 1.27 m (4ft 2in) longer, allowing for three additional passengers. In addition to doing more work on less kerosene, the Garrett TFE 731s are 11 inches larger in diameter (to accommodate the 2.82 bypass-ratio fan) but, weigh almost twice as much as the engines they replace (747 pounds to 392). The airplane was destroyed on the ground. The pulsating dc voltage is averaged and forwarded through the selector switch to the fuel flow indicator. Things seem to be just fine at the Lear jet factory. The 25G was introduced in late 1980 mainly to set or break some speed records for publicity. WebCertified to the stricter FAR Part 25, the $13.8 million Learjet 75 competes with the Embraer Phenom 300 and the Citation CJ4, beating them in cabin volume, with 364 cu ft (10.3 m 3) against 327 and 295 cu ft (9.3 Fuel burn at high-speed cruise: 1,079 lb/h (489 kg/h) at 451 kn TAS at FL470 The brake system utilizes hydraulic pressure for power boost. However, it has been often at the cost of fuel efficiency. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Parts are actually less of an issue with a 25 than you might think, because so many have been scrapped that you can usually find used parts. To demonstrate the how much the fuel those tip tanks hold, this is what can happen if a greenhorn fuel boy fills one wing with the other being empty. Interested in buying this aircraft click here. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. For practicing the return to the airport procedure, I start with 13,500 pounds Gross Weight so I can burn off 200 pounds of fuel on takeoff and return for a landing. Almost all Learjet models have one less fuselage window on the left side because the cabin door does not have a window as opposed to practically all Cessna Citations that do have a window centered on the door. It will also cost less to buy, and you won't have to pay MSP, but you will have to assume it will have only minimal residual value. A pressure switch will energize the pump if hydraulic pressure falls below a preset level and de-energize the pump when pressure returns to normal. So effective is this thicker wing cuff that the 25G can cruise at 0.81 Mach on the same fuel flow as the 25D cruising at 0.78 Mach. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. WebCertified to the stricter FAR Part 25, the $13.8 million Learjet 75 competes with the Embraer Phenom 300 and the Citation CJ4, beating them in cabin volume, with 364 cu ft (10.3 m 3) against 327 and 295 cu ft (9.3 Fuel burn at high-speed cruise: 1,079 lb/h (489 kg/h) at 451 kn TAS at FL470 Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Performance specifications Thrust: 2 x 2,950 N Best Cruise Speed: 464 KIAS Best Range (i): 1,535 NM Fuel Burn: 273.2 GPH Stall Speed: 91 KIAS Rate of climb: 6,050 FPM Ceiling: 45,000 FT Takeoff distance: 5,186 FT Landing distance: 2,703 FT Weights Gross Weight: 15,000 LBS Empty Weight: 7,640 ( All three installers are included. See their website at. The panel has been cleaned up, regrouped and made somewhat prettier. Or possibly several hours away from a commercial field? The Learjet 25D was first built in the mid-1970s but is still flying today. The official price of a barrel of Saudi Light crude oil was $12.37 in the mid-1970s. The Lear loves to be at FL400. Your burn rate is probably 140-175 gal/ hour, depending on power settings. (But the cargo door is still available as an option.) In master mode, 10 degrees of steering is possible. Conventional wing flaps are used to improve low speed flying characteristics and reduce landing and take-off speeds. I tend you use the Honeywell name for the engines. This is a review of the recently introduced Xtreme Prototypes Classic GLJ Model 25 Special Edition aircraft add on for FSX and P3D. The Learjet 25 is listed explicitly. Best Cruise: 417 KIAS You have to remember, VRSURGEON's mission is about 2.0 - 2.5 hours/ each leg for visiting family . No more barrel rolls by the demo pilots, no more geographic sales regions within countries, no more price cutting or undercutting sales prices by competing salesmen. The autopilot head unit is mounted on the lower center console immediately below the Fuel Control Panel. There were several Model 25 Learjets starting with the basic or original Model 25 that was introduced as the Stretched or Long Range Learjet. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. I was rewarded with free download links for a Learjet 24/25 Cockpit Reference Handbook and the Learjet 25 Operating Handbook that has the performance charts. Every type from fighters to helicopters from air forces around the globe, Classic Airliners Logically laid out, with tons of high resolution, close up screenshots with lots of bullets, detailed descriptions of every bit and piece of the aircraft, charts, tables, checklists, procedures, illustrations, references, known issues, and so much more. The force applied in the nose down direction is 80 pounds at the control wheel. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. The angle-of-attack transducer supplies a proportional voltage to the angle-of-attack of the aircraft. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. The engine compartments consist of an eight-stage axial-flow compressor directly coupled to a two-stage turbine, a through-flow annular combustion system, variable inlet guide vanes, controlled compressor interstage bleed, exhaust nozzle and accessory drive system. Dial markings are based on percent of maximum allowable engine speed. Due to the ease of converting the cabin the Learjet 25 has found a niche as a medevac aircraft. I remember Clay Lacy stating that Jet Fuel for the Learjet was 18 cents a gallon in Southern California when he was giving demo rides in the Model 23/24 in 1965. A safire is a four passenger jet (6 if you include the pilot seats) that sells for around $970,000 new. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. Neil Armstrong, the first man to walk on the moon, was a director at Learjet and set 3 climb time speed records in a Lear 28. - Aircraft data that you believe is inaccurate or have specific experiences. Fair enough. Just when I thought I had it all together and had a plan of action to get this review done by Christmas, along comes Black Friday week, then Cyber Monday and then all those extended deadlines. Due to the many buyouts, mergers and takeovers, Garrett engines may be referred using the original name Garrett AiResearch, or AlliedSignal, or Honeywell. How about time to climb to 15,000 meters (just shy of 51,000 feet) in 12 minutes, 27 seconds? Two spherical fire extinguisher containers can discharge their contents to either engine. Even more interesting might be why the Model 35 and 36 have that funny shaped 2-foot wing extension and why the plane is a foot or so longer than planned. If the red disc is ruptured, either or both the containers have been discharged overboard as a result of an overheat condition causing excessive pressure within the containers. The tip tanks provide additional fuel capacity to enable longer times aloft. Some of the milestones credited to Gates leadership was actually accomplished prior to the Gates takeover.
