If you are looking for an up-to-date modern design, high definition, and highly detailed Classic Learjet, you cant do any better than this one. So why are we talking about the Model 35/36 in a review of the Model 25D? Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. WebThe Lear 70 cruises 11% faster than the CJ3, and has an tremendous ceiling of FL510, allowing operators to climb into the smoothest air and optimize fuel efficiency. I get frustrated with the older autopilots but they usually do what they were designed to do. http://www.avsim.com/index.php/_/reviews/aircraft/review-learjet-24b-by-lionheart-creations-ltd-r2543, http://www.avsim.com/index.php/_/reviews/aircraft/review-a-comparison-of-2-jets-r2567. Photo: A Gates Learjet showing enormous size of fanjet engines. Microsofts planned layoffs will hurt MSFS or not? While writing this review, I got sidetracked with some new introductions to some of my older stuff that I had written reviews a couple of years ago. 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. It's got autopilots that will do everything but put sugar in your coffee. No extra charges for P3D. FC-110 with Yaw Dampers. Pilot workload is high and approach, landing and takeoff speeds are above average for civilian aircraft. Jump straight to the total cost table of the Bombardier Learjet 31. If utilization is 100 hours per year, that's about 20 trips a year. The big news is that the decreased fuel consumption increases the range of the airplanes about 40 percent. Interested in buying this aircraft click here. Get my point? The official price of a barrel of Saudi Light crude oil was $12.37 in the mid-1970s. Nice touch. WebFuel Burn: 257.4 GPH Stall Speed: 87 KIAS Rate of climb: 6,800 FPM Rate of climb (1 engine out): 2,050 FPM Ceiling: 51,000 FT Ceiling (1 engine out): 27,000 FT Takeoff distance: 3,393 FT Landing distance: 3,310 FT Weights Gross Weight: 13,500 LBS Empty Weight: 7,327 LBS Maximum Payload: 3,760 LBS Fuel capacity: 840 GAL Ownership The Bombardier Learjet 31 can cruise at up to 51,000 feet. The Classic GLJ Model 25 SE runs smooth as butter on my test system. A used Lear @ $675,000USD will cost more than the savings on a PC-12 over the course of a year. The fuselage tank can be filled by the wing boost pumps through the transfer line and the fuel transfer valve. Ouch. This point is near the aircraft centre of gravity and minimizes weathervaning when the chute is deployed under crosswind conditions. I did notice that the Sample Manual does not have the full Flight Planning section that is only available to those that purchase the add-on. Not only is this feature available, it is super simple to accomplish and even easier to switch to alternate avionics such as the large EICAS panel from the default Lear45 or most any other payware gauge that will physically fit in the designated area. The Bombardier Learjet 60 can cruise at up to 51,000 feet. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). Four additional shuttle valves connect the pneumatic system to the brake system for emergency braking. The drag chute is attached to the aircraft with a lanyard system that releases it from the aircraft should an inadvertent deployment be made while airborne. I was a dyed in the wool Cessna Citation fan for a long time and really still am, but you have to love the speed and power of these early Learjets. The brake valves are controlled via the rudder pedal toe brakes through mechanical linkages. I doubt not a single person could tell the difference when flying this add-on in any of the 3 sims, but it makes for more realistic loadings when I use real world flight planning data. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 Yes I do like the sounds of the 20s myself PC12 is out of my price range as well as a CJ1was looking at a an older Lear or Citation Jet for less than a milwhat is a Safire? Primary steering mode allows up to 45 degrees angle of turn and is suitable for slow speed aggressive steering maneuvers. The airplane was destroyed on the ground. Tail and Winglet closeups with beautiful airline logos. The Model 25D will climb with bursts at 8,000 fpm and will climb from Sea Level to FL430 in 13 minutes. But, the good news is that you will be flying one of the fastest civilian airplanes in the sky. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. March 28, 1980 - Gates Learjet flies high with its one-thousandth sale. The original tips were aligned with the longitudinal axis. Taxi operations are accomplished using the electronic nose wheel steering. WebThe Learjet 25 generally has five fuel tanks. WebFuel Burn: 257.4 GPH Stall Speed: 87 KIAS Rate of climb: 6,800 FPM Rate of climb (1 engine out): 2,050 FPM Ceiling: 51,000 FT Ceiling (1 engine out): 27,000 FT Takeoff distance: 3,393 FT Landing distance: 3,310 FT Weights Gross Weight: 13,500 LBS Empty Weight: 7,327 LBS Maximum Payload: 3,760 LBS Fuel capacity: 840 GAL Ownership I've never flown the Lears, but wouldn't an old 25 have a hard time with noise restrictions at most airports? Any changes are a little more difficult until you fully understand the logic and procedure. The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. I was disappointed that the developer did not include any climb, descent, or cruise performance charts in the Flight Planning section. See this picture and article found in the June 23, 1969 edition of Aviation Week and Space Technology magazine. A jet pump and electrical boost pump are mounted in each wing tank near the centre bulkhead to supply fuel under pressure to the respective engine fuel system. The Model 35/36 would go on to sell an astounding 738 units. Me, I would not touch a Lear 25 just because of age. Single engine performance is good with the single engine rate of climb approximately 1700 feet per minute at gross weight at sea level and a single engine service ceiling of approximately 21500 feet. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. The large markings are graduated in 2% increments from 0% to 100% and the small dial is graduated in 1% increments from 0% to 10% to allow the pilots to accomplish more precise engine speed settings. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Or you could always get a Notar. Every conversation stressed the Learjets FAR 25, Transport Category certification, the very same certification level as a Boeing 747. Garrett fanjet Engines for the Model 35 a real hodgepodge of parts. I just need to find the time to find all those 80 animations in the cockpit. You need to factor in that at today's fuel price, you can pay anywhere from $3.75 to 8.50 per gallon of Jet A. WebThe 25 seats up to 10 passengers plus 2 pilot (s). Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). Intersting. In case you just skipped over the CJ610 engine history, the highlights are that every production Model 20 series was powered by some version of the GE CJ610-1 through the CJ610-8A turbojet engine rated at 2,850 or 2,950 lbst. In 1970 the Learjet 25B was produced along with the Learjet 25C in the same year. This puts the crew on a longer arm to help bring the cg within the envelope. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. . 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 Learjet 25 is similar to the Model 24 but is 1.27 m (4ft 2in) longer, allowing for three additional passengers. Please send us your experiences on your aircraft. The pitch would be to corporate American and the world that the new Learjet was a safe and efficient means of doing business. Now about that General Electric CJ610 turbojet engine. Exactly which specific model is this Classic Learjet? Monobromotrifluoromethane (CF3BR) is used as extinguishing agent. The brake system incorporates four power-boosted disc-type brakes with integral anti-skid system. Founder of AVSIM Online. There is no doubt that I totally overlooked several items that probably required months to research and code and I didnt even notice or failed to suitable take notice. They are practically identical to the engines in the supersonic T-38A Air Force jet that the Thunderbirds flew for years, except the civilian version does not have the afterburner. These numbers were soon eclipsed by Cessna and their Citation line of business jets. When all was said and done, this New Version of the Learjet 25 was none other than the Model 35 which first flew more than 4 years later on August 22, 1973 but, not certified for almost another year in July, 1974. The 35 has a bench-style rear seat that will accommodate two wide bodies, or 3 very thin ones on short trips, four forward facing chairs and a side-facing potty/jump seat opposite the door. The time required to accelerate from idle to 100% RPM is approximately four seconds. WebEvery Lear that comes out of the factory is equipped to fly itself. Learn about cockpit equipment upgrades that are FAA mandated. Make sure you checkout the Approach plates and the iPad on the side panels. These two important reasons are near the top of the priority list, but the fact that most everyone was convinced that taming the noise levels of this military adapted gas guzzling high performance turbojet engine was going to be near impossible. Best Range (i): 1,590 NM Fuel Burn: 256.0 GPH Stall Speed: 90 KIAS Rate of climb: 6,900 FPM Ceiling: 45,000 FT Takeoff distance: 3,393 FT Landing distance: 3,310 FT Weights Gross Weight: 12,499 LBS Empty Weight: 6,150 LBS Fuel capacity: 834 GAL Ownership Costs 1965 Total Cost of Ownership: Register For Free Total Fixed Cost What is missing in the Manual? The vortex generators, those rows of little metal tabs, and small fences were replaced with newly designed cuffs for the wingtip fins and Boundary Layer Energizers, BLEs. The bleed air is cooled in the heat exchanger by ram air entering the dorsal fin inlet and passing through the heat exchanger. AC current is provided by two 1000 Volt-Amperes (VA) solid-state inverters.

If you own the previous 20 Series add on from XP, keep in mind that this version 2.0 Special Edition is not an update or upgrade - this is a totally and completely redesigned new version. 1. There were several Model 25 Learjets starting with the basic or original Model 25 that was introduced as the Stretched or Long Range Learjet. Gates was able to immediately improve the financial stability of Lear Jet and brought in their kind of proven management controls and marketing savvy that had generated profitable and dynamic growth of their parent company Gates Rubber for the last 55 years. This added a stall strip and full-chord wing fence to create an aerodynamic warning and a straight-ahead stall. The EICAS panel can be added from the default Lear45 with a couple of lines of code added to the panel.cfg file and then cycled with one click on a hot spot on the VC panel to the standard GPS or Flight1 GTN750, should you own one. MSFS beta update [1.30.12.0] - January 17, 2023. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. WebThe Lear 70 cruises 11% faster than the CJ3, and has an tremendous ceiling of FL510, allowing operators to climb into the smoothest air and optimize fuel efficiency. The Flysimware Lear fuel burn more or less works out when using a M0.71-M0.72 cruise, which I've always considered to be quite slow. Search for the string learjet 24/25 MrMoo pdf. So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. ), Please tell us: I know, I know why dont the developers get away from the round dial old stuff and give us a Lear 60XR with a fully integrated ProLine 21 system? During ground operations, a solenoid limits the pressure differential to 0.25 psi in order to ensure normal functioning of the door and emergency exit. The nose wheel has a specially moulded tire to prevent water splashing into the engines. (But the cargo door is still available as an option.) The 30 series have much more fuel efficient engines, not to mention quieter. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. Hanger, insurance, service, unscheduled maintenance,de-icing, etc., you truly need to be prepared for the "real world" costs of ownership. This is a glide ratio of 16 to 1 and is based on a wings level glide with gear and flap up and a gross weight of 11000 to 12000 pounds. Heck, if Learjet can do it, why cant we. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. It is simple enough to modify the fuel capacity for a fuel tank and it is easy enough to modify the Empty Weight of the aircraft. This was caused by the weight of all that fuel in the tip tanks. Good luck. On the east coast of the U.S. center contollers will not allow you to get to those altitudes very quick making the aircraft sucking the fuel down. The original design guideline was to increase thrust over the GE turbojets just enough to make sure the new model was at least as fast as the Model 25 that it was to replace. It would have been a wonderful addition if they had spent another day or so and added the climb, cruise, and descent details to the example. In addition to the speed efficiency the 25G gained 370 nm in range compared to the normal 25D. 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. The 31 is also still in production, although speculation is that the 31 line (which has been very sluggish) will shut down with the introduction of the 40. Each system has a detailed description along with a key to every switch, gauge, and instrument. All rights reserved. The CJ610-6 engines fitted to the Learjet 25 have very low inertia and accelerate rapidly. 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. One click on the 8-Track tape player will start, move to the next selection, or stop the music. The Century III wing modification alone lowered the final approach speed by an astounding 15% without any loss of cruise speed while reducing the landing distance by nearly 1,000 feet for the new Model 35. No warranty of Before we get into the specifics of our Xtreme Prototypess simulated GLJ 25 SE model, I would like to tell you the story, very abbreviated of course, of the trials and tribulations of designing a replacement for the Model 25. Review: Classic GLJ Model 25 Special Edition, The Janitor - An Interview with Tom Allensworth, Interview with Joshua Howard Re MS FLIGHT - March 2012, Interview with LMOC Re P3D - September 2012, The AVSIM Hack - First Published in May, 2009, The AVSIM Hack - The Full Story - Published April 2013. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. You can read those reviews here and here. The GE CJ610-8A engines came directly from the military inventory. 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. I especially like the fact that we get all three installers, 10 very nice repaints, an outstanding flight manual and a highly tuned flight model that will cruise at Mach 0.82. The control wheels operate the elevator and ailerons mechanically through a system of cables, pulleys, push-pull tubes and bell cranks. Although Lear is saying the 35 and 36 have eight- and six-passenger cabins respectively, the arrangements theyre showing are really seven and four for practical purposes. I cant speak for the Legacy systems, but Ryan Butterworth says he has a something less than the best system and he has posted some Frame Rates compared to some of his other addons. The 40 is a 45 that has about 26 inches chopped out of the fuselagealso in production and certification with first flight scheduled for March. A drag chute is fitted as optional equipment on some Learjet 25 aircraft. Now, that would be ideal, maybe even make a video. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. Mainly because the two models were designed and built alongside each other and practically all the improvements being designed for the newer, slightly larger and better selling Model 35/36 were also being applied to the Model 25 provided it was cost efficient. This graphic show how different, yet how similar the full line of Learjets are from the first Model 23 to the most popular of the modern large cabin Model 60XR. Many times I receive offers or invitations to review a product and the offer comes at an inconvenient time mostly due to my haphazard work schedule. Embraer is the latest manufacturer entering the business jet market with the Phenom and Legacy lines of business jets. A 25 will burn more fuel, of course, but that's only part of the equation. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. The Bombardier Learjet 31 can cruise at up to 51,000 feet. What about a King Air 90 or Cessna 421? 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. Engine bleed air is admitted through a flow control valve to a heat exchanger. Both are powered by aft-fuselage-mounted, twin Honeywell TFE731-40BR turbofans, with a top speed of an impressive 535 mph (465 knots) and an average fuel burn of just under 200 gallons per hour. The Model 28 and 29 Lears were test beds for adding winglets and testing early version of the eventual Garrett AiResearch fanjet engines that were first used for the Model 35 and 55 Longhorn. They even had the engine model numbers and thrust level properly identified. The oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. So, in summary, it appears that Gates was going down a path of basically adding two new engines and whatever electrical, mechanical, hydraulics-wise and otherwise was required to make them work on an existing well developed airplane to move from turbojet engines to fanjet engines. This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. Intersting. Even with a 35 look for as new as you can afford. There were no plans to increase the length or height of the small tube fuselage so this Model 35 would not be in competition with the future 40 and 50 series enlarged fuselage models. You will find more and more nifty features designed into this add on as you spend more time flying. Only $1.1 MM for the full mod. The Models 35/36 and all the winglet models have much larger engines cowlings and a slightly longer fuselage than the Model 25D. To correct for the wing drop, in 1979 Gates introduced another improvement call Softflite. The normal pressure relief valve will open at 8.9 psi differential pressure and the safety outflow valve will open at 9.2 psi differential pressure which is the maximum allowable differential pressure. Any Learjet 25s that have not been modified by installing noise compliant engines or "hushkits" will not be permitted to fly in the contiguous 48 states after December 31, 2015. Is this a review on a flightsim website, or Wikipedia ? The valves are controlled by the FIRE switch and activation of these valves are indicated with pinhead lights located in the cockpit next to the FIRE switch. The 25G was introduced in late 1980 mainly to set or break some speed records for publicity. 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. Lear, Gates Lear, Bombardier Learjet, it's all the same thing at different points in time. That one is indeed in work and will, most likely be available by a different developer in the next couple of years or so, maybe sooner. I wonder why they decided to start with a new version 2.0? . Most accounts state that 64 base model 35s were built before the Models 35A and 36A arrived with upgrades throughout but mostly increased fuel load and therefore increased endurance. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. During a series of demonstration flights lasting from June 9 to 18, 1982, the 25G broke a number of long-distance speed and fuel consumption records. I use the following for my personal flying in the flight sims. autopilot. So, 10 percent of this essay, is "Review", and 90 percent about the history of the Learjet ? The problem it creates for me is that I have so many similar Learjets that after a while many of the systems seem to run together and I start confusing one with another. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. Oxygen is always available for the crew and can be made available to the passengers manually or automatically. [2], Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on the aft fuselage. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. The nose gear doors operate mechanically with linkages attached to the nose gear shock strut. This GLJ 25D (rw) would have been required to have the standard Fuel Jettison pumps, switches, and lights working for any flight. I would like to recount the history of the General Electric CJ610 engine used in all the 20 series Learjet models, including our GLJ 25SE and hopefully get back to the story of how the original Garrett AiResearch TFE731 engine came to be. The AirNav price of Jet A fuel is currently somewhere between a low of $1.99/gal and a high of $9.00/gal with an average of 3,682 FBOs nationwide of $4.11/gal. hmm. The Venezuelan armed forces forced the Learjet to land on suspicion the aircraft was being used for "illicit activities," possibly involving drugs smuggling. If it floats or flies rent it. Some of this research was done for the Lionheart LR24B review and the follow-on comparison of the Learjet 24B to the T-38. It is our mission to be the go to leaders in the aviation industry. 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. On aircraft 25-181 and subsequent the variable volume engine driven pump delivers fluid under a pressure of 1450 psi to the system and static pressure is maintained at 1500 to 1550 psi. 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 aircraft description and specifications section, instrument panels, systems description have their one chapter or section along with a an excellent flight planning chapter. Understand that age equals maintenance because things wear out. 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. However, it has been often at the cost of fuel efficiency. The Normal Checklist and Procedures are far more than simple lists each item has a reference to a page number and a figure in the manual in addition to the action required. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour.
