The Lear loves to be at FL400. Neither was long range endurance it was pure speed and the ability to get over the weather that moved corporate aviation to the jets. The Gates Rubber Company purchased all of Bill Lears interest for about $28 million in early 1967. 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 But, there's nothing like giving the " finger" to the commercial flying world! The Bombardier Learjet 45XR can cruise at up to 51,000 feet. I am in the business.been flipping large commercial jets to airlines for 15 years. Garrett fanjet Engines for the Model 35 a real hodgepodge of parts. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. I like this Classic Learjet a lot. Bottom Line: A most definite Buy Rating. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. Robertson, of STOL fame, also took a crack at adding small winglets on top of the wingtip fuel tanks to try to enhance the endurance of the Model 25 along with replacing the GE CJ610 engines with PW JT15D-5 engines to add STOL capability to the already hot Model 25. My screen images are not as sharp as it should be but, I just cant seem to find to time to tweak it. It took a year or more to realize they really needed an updated Model 35A and an extended range Model 36A. Now, that would be ideal, maybe even make a video. Our GLJ 25SE flight model does indeed have the updated BLEs instead of the older vortex generators. I use the following for my personal flying in the flight sims. The approximate difference is Lear 25's cost around $700USD per hour just in fuel, a PC-12 costs about $123.50. Despite being used at lower altitudes and equipped with small landing gear, the Learjet can land on gravel runways if it is fitted with a special "gravel kit". WebThe 25 seats up to 10 passengers plus 2 pilot (s). Lear never used an A designator for any production Model 25, only on the Model 24. 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. 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. The fuel inefficiency, the limited range, and the airport noise problem. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes Founder of AVSIM Online. Mr. Gates took over as President and COO of Lear Jet and Bill Lear stayed on for a year or so as Chairman but wasnt involved in the Lear Jet project or day to day operations. I read that this new VC has over 1,500 parts and 250 custom systems, animated gauges, switches, knobs, levers, light indicators and flight instruments. Some aircraft have a 1000 VA auxiliary inverter that is used as an option for added system capacity. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. All the early or classic Learjets had to burn off about 2,000 pounds of fuel to get the weight down to the Maximum Landing Weight. This has always been a choke point, restricting airflow and creating drag at high speed. I now have these items properly introduced and scheduled in my new more leisurely work schedule. Discussion in 'Aviation Chat' started by vrsurgeon, Aug 3, 2012. Hopefully Flysimware will tweak this accordingly. The 51,000 feet altitude Certification was added for all 25D/F models, although the specs are a little vague in the XO manual. ( The drag chute has been deployed in a crosswind of up to 20 knots under actual test conditions. This puts the crew on a longer arm to help bring the cg within the envelope. They even had the engine model numbers and thrust level properly identified. What is not shown in the accompanying artists sketch is just how large those new Garrett engines would be, or the fuselage stretch, or the increased wing span with that now familiar looking two foot section added out near the tips. . Due to the many buyouts, mergers and takeovers, Garrett engines may be referred using the original name Garrett AiResearch, or AlliedSignal, or Honeywell. As those folks that built or bought homes near the new airports and then discovered just how loud these little Pocket Rocket Learjets could be as their dishes rattled and windows vibrated they pressed for more and more stringent noise controls. High Speed Cruise 475 kts Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. Starting ignition is provided by a dual output capacitor-discharge system. Intersting. It is possible for gravel from an improperly packed gravel runway to be sucked into the engines causing "foreign object damage", thus the need for the kit. For some reason, this XP GLJ 25D SE has all the switches and lights but does not have the system coded. 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. This is an FSX limitation, no Ramp Weight field. Bob Berry, Lears engineering test pilot and director of product assurance, says the program calls for the airplanes to have the same performance and handling characteristics of the Model 25. MSFS beta update [1.30.12.0] - January 17, 2023. The thrust reverser paddles are removable with a single click so we can see the partially hidden switches. 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? Both military and civil versions, Blimps / Airships If utilization is 100 hours per year, that's about 20 trips a year. Only $1.1 MM for the full mod. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. Heck, if Learjet can do it, why cant we. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. Simply put, a shorter cabin to make room for more fuel. The Bombardier Learjet 31 can cruise at up to 51,000 feet. The 30 series have much more fuel efficient engines, not to mention quieter. 100 hours a year isn't worth owning an airplane. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. 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. This Century III wing enhancement was introduced by Gates in 1976 for the new Model 35, but we also got the benefit because the Model 25D was a concurrent production airplane in the late 1970s. GlobalAir.com is your partner in connecting you with relevant information and resources. The lower console is now wider, not double wide, but somewhat wider. 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. Everything from the Goodyear blimp to the Zeppelin, Night Photos This Century III wing did not alter the Learjets tendency to roll off sharply during a stall. With this setup I can use standard weights of 170 lb men and 120 lb women and carry a small amount of baggage with full fuel and be slightly under Max Ramp Weight of 15,300. 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. Some of this research was done for the Lionheart LR24B review and the follow-on comparison of the Learjet 24B to the T-38. They already knew how to build jets that would fly faster and higher than the competition, now they needed to increase the number of seats, expand the cabin width and height, add some small things like toilets and food service, and extend the endurance with larger and more efficient engines. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. The GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. Beautiful shots taken while the sun is below the horizon, Accidents This created a little unexpected legroom in the cabin, and they even gave the crew a few more inches. Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. Search for the string learjet 24/25 MrMoo pdf. The brake system incorporates four power-boosted disc-type brakes with integral anti-skid system. I have been told that the aircraft likes the dutch roll during landing approach or the student like to do it and you need to declare fuel critical while taxing out. Some of the animations only work either in the Lockheed Martin P3D edition or FSX, but, the performance and pleasure of flying a high performance classic Learjet with 3d gauges in an ultra HD virtual cockpit using our latest 3rd party avionics is outstanding. The Venezuelan armed forces forced the Learjet to land on suspicion the aircraft was being used for "illicit activities," possibly involving drugs smuggling. Thanks to Alain Rouleau at xtremePrototypes.com for answering all my questions and providing the evaluation software. This combination makes the 35 and 36 much less costly to operate than a 25B or C and it will give them one of the best single engine angles of climb of any of the jets. The Learjet 25 cabin is pressurized to enable high altitude operations without the use of supplemental oxygen. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. Nose wheel steering is electronically controlled by the rudder pedals, utilizing the synchro principle. WebThe Learjet 25 generally has five fuel tanks. The engine fire system is of the continuous-element type and will provide a FIRE warning indication to the crew in the event that the rear nacelle area temperature exceeds 510 degrees Fahrenheit or if the forward nacelle area temperature exceeds 480 degrees Fahrenheit. The often mentioned price of Jet fuel in 1975 across the nation was less than 30 cents/gallon, but would go absolutely insane a few years later. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. Some of the milestones credited to Gates leadership was actually accomplished prior to the Gates takeover. No extra charges for P3D. The original tips were aligned with the longitudinal axis. 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. 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. After a honest introduction to the turbine world, will you feel that playing with Ferrari's are chump change, by comparison. The Model 25C also has an optional two bed sleeping compartment. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Leasedont buy. Of course, I always reserve the right to refuse but should I take the add on, I always do my best to provide a fair and balanced review. 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. 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. 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. The Model 31A /ER was the long range version which added an additional 275 miles to the range. hehehehe. 60 somethin gallon tank, 300nm+ range, I've stayed airborne for over 3 hours on one tank.

So why are we talking about the Model 35/36 in a review of the Model 25D? I tend you use the Honeywell name for the engines. Fuel flow is indicated via a fuel flow system. Props and jets from the good old days, Flight Decks The Model 25G received a thicker wing section where the wing joins the fuselage. The leading edge of the standard wing sweeps back at a 13-degree angle to a straight trailing edge. A jet pump installed in each tip tank transfers fuel into the wing tanks. 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. There were several Model 25 Learjets starting with the basic or original Model 25 that was introduced as the Stretched or Long Range Learjet. Two disc-type indicators are flush mounted under the left engine. There were only a handful of 20 series models after the 25D. Xtreme Prototypes hybrid model the Classic GLJ Model 25 Special Edition is based on one of the last true or original Lear Jet designs at the start of the Gates Learjet tenure. The indicator face is divided into green (safe), yellow (caution) and red (danger) segments. ). The main gear is enclosed by two doors after retraction. 1. 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 by the manufacturer or FAA. The first modification to the original Learjet wing came in 1970 when the tip tanks were realigned. The Model 35/36 would go on to sell an astounding 738 units. The hydraulically retractable landing gear is of conventional tricycle configuration with air-hydraulic shock-type nose and main gear. You can only carry so much fuel and still have room for a few passengers. This is a review of the recently introduced Xtreme Prototypes Classic GLJ Model 25 Special Edition aircraft add on for FSX and P3D. Small stall strips were place on the leading edge with a newly designed stall fence. This one breaks new ground in advancement and efficiency because it is an all new design specifically intended for new high end PCs using the most up-to-date version of FSX:SE and Lockheed Martins P3D v2-3. A green overboard indicator on the outside surface of the dorsal fin will be ruptured or missing to indicate that the rupture disc is not intact. The time required to accelerate from idle to 100% RPM is approximately four seconds.

Disclaimer: Information on this site may not be accurate or current and is not valid for flight planning or any other aircraft operations. The pulsating dc voltage is averaged and forwarded through the selector switch to the fuel flow indicator. By 2018, 1970s Learjet 25s were sold for under $200,000. A check valve prevents reverse flow between the containers. So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. 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. You will find more and more nifty features designed into this add on as you spend more time flying. Two shuttle valves in the pressure lines prevent fluid feedback between the pilot's and copilot's pedals. ) 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. The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. How about time to climb to 15,000 meters (just shy of 51,000 feet) in 12 minutes, 27 seconds? Best Cruise: 417 KIAS I'm not trying to dissuade you, just make you understand the JOYS of ownership! Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Lears made their mark with exceptional speed and high-level cruise. 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. Exceptions may be granted. XPs GLJ 25 was inspired, according to the manual, by the Model 25D with a few real world options added, such as the Dee Howard thrust reversers, Century III wing with SoftFlite Boundary Layers and some more recent additions such as the availability to add some of our 3rd party avionics to the VC panel such as the popular Flight1 GTN 650/750 combo or one of the newer weather radars. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. Here is a recent price break down from Business and Corporate Aviation magazine. The largest seller is the Model 25, but more 35s were sold in the past six years. Not only the F1 GTN but you can also have your working REX/Milviz Advantage weather radar. True! One of Gates priorities was to improve the low speed handling of the Learjet while keeping the top end speed somewhere in the low Mach 80s. As most of you already know, Bill Lear invented the autopilot during World War II, and every Learjet that ever left the factory came with a Bill Lear designed J.E.T. Or you could always get a Notar. Of course, the Model 25 was an improvement of the Model 24 that had replaced the original Model 23 the one that started it all. 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. The H-valve position can be adjusted by the crew to increase or reduce the amount of bleed air cooling at the heat exchanger. I also changed the MTOW to read 15,300 (Max Ramp Wt) knowing I will be at the official 15,000 MTOW with a few minutes of taxi time. WebThe Learjet 25 generally has five fuel tanks. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 psi. 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. The engine compressor inlet and turbine discharge pressures are sensed by the EPR transmitter and transformed into an electrical signal that is transmitted to the EPR indicator. 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 On April 10, 2014, a privately owned Learjet 25D was destroyed on the ground by Venezuelan forces. 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. The 36, because the normal behind-the-aft seat baggage area was removed to make room for the larger fuselage fuel tank, has a small luggage area opposite the door under which a slide-out potty is stowed. 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 lanyard is attached to the aircraft at the forward end of the tailcone access door opening. 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. FAA certified on September 4, 1970. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. In 1974 the Peruvian Air Force purchased two 25Bs with a belly pod that contained an aerial survey camera. Even better would be a full-blown tutorial flight or example flight. 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. The low pressure compressor was taken from Garretts 660-series APU used on the 747, the high-pressure impeller is scaled from one used in the TPE 331 and T76 engines, and the turbine components are from the APU used in DC-10s. 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. (But the cargo door is still available as an option.) On May 17, 2017, a Learjet 25B registration XA-VMC operated by the company Aerotransportes Huitzilin S. A. de C. V. crashed at 3:26p.m. local time shortly after taking off from Toluca International Airport, Mexico bound for Durango. It comes only as a pdf and in two editions the full blown 160 pages that in provided to registered user and a still excellent 70 page Sample Version for those who wish to see some detail prior to purchase. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. This GLJ 25D (rw) would have been required to have the standard Fuel Jettison pumps, switches, and lights working for any flight. Check column 5, for the 1,000 nm comparison of the fuel burn. 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. Credit: FROM THE OCTOBER 1973 BUSINESS & COMMERCIAL AVIATION. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. Improved version with greater fuel capacity. Photos: Original Model 23 (at Smithsonian) on left, yet to be built Model 85 on right. In 2013, the FAA modified 14 CFR part 91 rules to prohibit the operation of jets weighing 75,000 pounds or less that are not stage 3 noise compliant after December 31, 2015. The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). 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. What about a King Air 90 or Cessna 421? The engine pressure ratio (EPR) system enables the pilot to obtain power required to meet certified aircraft performance without exceeding engine limitations. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. I read that you can expect to find 80 animations and in another paragraph I read that there were hundreds of cockpit animations so start looking and expect a few pleasant surprises. It is almost always mentioned the reason for the push to abandon the GE 610 turbojet engines was the spiraling cost of jet fuel and the fact that just about every ounce of efficiency had already been squeezed out in the many upgrades and modifications since the first Lear 23 flew with the 610-1 version. But first, they needed to stop the bleeding and improve the cash flow at their newly acquired Learjet factory. 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. One big problem it would not solve is the headroom and elbow room. A Denver based subsidiary Gates Aviation, was already a major Lear Jet distributor so they already knew a lot about airplanes and specifically the Learjet. How much does it cost to operate these aircraft? Thanks for the info..that was a great help? The 25G was introduced in late 1980 mainly to set or break some speed records for publicity. The Model 31/31A would be the final adaptation of the small bore fuselage but add large delta fins at the rear for yaw control and added 4 foot extensions to each wing with 4 foot high winglets for improved efficiencies and more docile handling. These boundary layer energizers are small spanwise ridges on the upper wing surface just ahead of the aileron. There are so many flying around on medical runs, express cargo services etcI often wonder how much profit they compaines make on each flightI heard they charge big bucks the 20 series learjets are cheap to aquire but the fuel bill is a different story. - Send us pictures of your plane. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. 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. WebThe 25 seats up to 10 passengers plus 2 pilot (s). To overcome the problem, they added 13 inches to the fuselage ahead of the wings leading edge. In master mode, 10 degrees of steering is possible. 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.

I think the upper level VMO is actually 350 kts, provided it has the Century III wing. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. Typical Price: $2,296,212.00 One of my favorites is the show/hide throttles feature so I can see the light switches. Just so you know the details Timberland shoes, Flysimware Learjet 35, SPAD.next, Volair Avionics Panel, and the new Aerofly FS2 simulator. WebEvery Lear that comes out of the factory is equipped to fly itself. I suppose you heard the current joke, Owner - How much do you think my beautiful, well maintained Gates Learjet 25 is worth? Salesman That all depends on how much fuel is in the tanks! Sigh. Our large helicopter section. Moving the tip tanks out undoubtedly added inertia and so, to increase lateral control without heavying up the feel, spoilerons are now used for additional roll command. The official price of a barrel of Saudi Light crude oil was $12.37 in the mid-1970s. To complete the design efforts that started with the somewhat simplified plan of upgrading the Model 25 with newer fuel efficient and quieter engines with a little more thrust turned into a longer, wider, more powerful new model with much improved low speed handling while retaining excellent cruise speeds at the highest flight levels allowed.
