Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). This has always been a choke point, restricting airflow and creating drag at high speed. I decided on an Empty Weight of 7,168 pounds and a total fuel capacity of 1,055 gallons. 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 51,000 feet altitude Certification was added for all 25D/F models, although the specs are a little vague in the XO manual. L-188, this rumor comes from a PC-12 operator up here, namely me. As a matter of fact, Gates announced at the Paris Air Show of 1969 what appeared to look and sound like a Model 25 with new Garrett fanjet engines. I understand that a new French language edition of the manual is almost complete. Just about any gauge can be added to this area with a little adjustment to the height and width of the gauge to fit the area available. An audible waning horn warns of flap extension to more than 25 degrees if the landing gear is not down and locked. - Aircraft data that you believe is inaccurate or have specific experiences. If utilization is 100 hours per year, that's about 20 trips a year. WebThe Learjet 25 generally has five fuel tanks. Each system has a detailed description along with a key to every switch, gauge, and instrument. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. They have their own book for the 30 series Learjets. The Venezuelan armed forces forced the Learjet to land on suspicion the aircraft was being used for "illicit activities," possibly involving drugs smuggling. A duty cycle of 3 minutes on and a cooling period of 20 minutes off is required to avoid overheating the pump motor. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. When the tank is full, a float switch de-energizes the wing boost pumps and closes the valve. All rights reserved. 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. A check valve prevents reverse flow between the containers. 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. VRSURGEON also didn't state where his Family is, possibly not near a commercial field? This would solve all three disadvantages of the Model 25 Learjet. Many don't put that on their FCar in decades. In normal cruise, the tip tanks are streamlined with the airflow, reducing drag, even though the tanks appear to droop when the plane in parked on the ramp. A jet pump installed in each tip tank transfers fuel into the wing tanks. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. WebEvery Lear that comes out of the factory is equipped to fly itself. Twin engine turbojet aircraft. (But the cargo door is still available as an option.) 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 You really need to do your self a favor, and go to your local private airport, find a Company that does Lear maintenance. The XP design team did a good job with what they had to work with. No warranty of The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). Being an optimist and knowing the Xtreme Prototypes design team, both of them, love their work and their products, just might be receptive to making this addition. [2], Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on the aft fuselage. Approach reference speed was cut by 12 knots and the landing runway requirement was reduced by more than 800 feet. Rest assured, the productionl ine is still rolling right along. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. Photos: Original Model 23 (at Smithsonian) on left, yet to be built Model 85 on right. Good luck. Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. Intersting. A tank cross-flow valve is installed to prevent fuel transfer between 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. 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. Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). I use the following for my personal flying in the flight sims. Sorry, sometimes I get carried away with this stuff. 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 As the wheel rotation speed accelerates to normal tolerance limits, normal braking pressure is restored. I need something cabin class that is cheap to fly for about 1 hour legs. (the Learjet 25D was certified for FL510). Pilot workload is high and approach, landing and takeoff speeds are above average for civilian aircraft. Wheel speed transducers in each main wheel axle induce an AC frequency on the DC voltage input proportionate to the wheel speed as they are driven by the wheels. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. The original model 25 wing had a fairly sharp leading edge designed for high-speed cruise. 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 For instance, Gates supposedly upgraded all the production models to FAR 25, Transport Category certification level aircraft, while in fact the Model 24/24A aircraft were certified as Part 25 aircraft 8 months prior to any Gates involvement and the Model 25 was already in the approval process. 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. 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. Ouch. You know, that old just a few more lines of code, thing.. Our GLJ 25SE flight model does indeed have the updated BLEs instead of the older vortex generators. The angle-of-attack transducer supplies a proportional voltage to the angle-of-attack of the aircraft. I think the upper level VMO is actually 350 kts, provided it has the Century III wing. 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 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. Tail and Winglet closeups with beautiful airline logos. This doesnt raise the cruise speed Mach limits but does provide a greater safety margin in turbulence or when maneuvering at high speeds. This is from the XP Flight Manual. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. They even had the engine model numbers and thrust level properly identified. The Phenom 300 is marketed as direct competition of the smaller Bombardier Learjets and Citation CJ3/CJ4. MSFS beta update [1.30.12.0] - January 17, 2023. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. Let's not even talk about the cost in maintenance on a 30 year old plane. If you happen to be overtaken at normal cruise, which could be at 51,000 feet, it will be one of the Gulfstreams or a Citation X or another Learjet. Just use the Find function and locate the values in the aircraft.cfg file and make your changes. 124.2 The Learjet 25 also requires long runways at high altitude or ambient temperature. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. 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. fitness for any purpose is made or implied. Understand that age equals maintenance because things wear out. 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. 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. 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. This pales in total numbers when compared to the Cessna Citation family of business jets that is more than 6,000 and counting. This added a stall strip and full-chord wing fence to create an aerodynamic warning and a straight-ahead stall. 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. The pointer responds to the dynamic pressure from the pitot heads on the nose compartment. 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. Maybe missing is not the correct word, but I sure do miss the ability to perform a fuel dump or fuel jettison procedure so I can practice returning to the airport after taking off with a full load of fuel. 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. Everything from the Goodyear blimp to the Zeppelin, Night Photos The engine pressure ratio (EPR) system enables the pilot to obtain power required to meet certified aircraft performance without exceeding engine limitations. Plus, the first jets, straight jets, ate fuel like it was going out of style, and they had quite a restricted range, This is not exactly what Bill Lear was telling his potential customers at the time, but was obvious to the new Gates team that had to pick up the pieces and move forward. Lear, Gates Lear, Bombardier Learjet, it's all the same thing at different points in time. The real world Model 25D was in production from 1976 to 1982, long after Bill Lear had moved on to other things, but was, in fact, just one of the many variations of the Model 25 that was a true Bill Lear design. 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. You need to be a member in order to leave a comment. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. On April 10, 2014, a privately owned Learjet 25D was destroyed on the ground by Venezuelan forces. When the aircraft speed is 7% above stall, the stall warning energizes a control column shaker that produces a low-frequency buffet signal through the control column to warn the crew. Oxygen is contained in a pressurized bottle located in the dorsal fin of the aircraft. The H-valve position can be adjusted by the crew to increase or reduce the amount of bleed air cooling at the heat exchanger. You can only carry so much fuel and still have room for a few passengers. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. I like this Classic Learjet a lot. When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. I suggested the Empty Weight be reduced from 8,120 to 7,468 and the fuel load increased to 910 gallons. The Go Around feature is especially well done, be sure to learn more about it. 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, Search for the string learjet 24/25 MrMoo pdf. Fuel flow is indicated via a fuel flow system. Back in the real early days, fuel efficiency wasnt a big concern mainly because jet fuel only cost 18 20 cents a gallon. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Hopefully Flysimware will tweak this accordingly. This puts the crew on a longer arm to help bring the cg within the envelope. The chute offers an addition safety margin, since it can significantly reduce the stopping distance. 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. This Model 35/36 would be the last Learjet with those large wingtip fuel tanks. The 30 series have much more fuel efficient engines, not to mention quieter. The Bombardier Learjet 31 can cruise at up to 51,000 feet. Things seem to be just fine at the Lear jet factory. The best glide distance with engines windmilling is obtained with a clean airplane configuration and with a glide speed of 160 to 170 knots. Here is a photo of a Model 25 test plane with a Garrett fanjet on the right and a standard GE CJ610-6 turbojet of the left side. Ouch. The real world procedures are much easier than the simulated ones mostly due to the AP switches mounted on the control wheels in the real airplane not being accessible in our flight simulator add on. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes I was at the Lear factory in Wichita about a month ago. Remember, back at the time of production, the Model 25D was a full million dollars cheaper than a new Model 35. I just need to find the time to find all those 80 animations in the cockpit. ) And, of course, the TFE 731 meets FAR 36 noise requirements and is a much cleaner running powerplant than the GE was. The Fuel Jettison switch and lights are already installed on the add on Fuel Control Panel, it just needs a little more code added to make the system work. But, the standup and walk around Learjet cabin would arrive at a later date with the 40 and 60 series. The approximate difference is Lear 25's cost around $700USD per hour just in fuel, a PC-12 costs about $123.50. The main gear has dual wheels and brakes on each strut. The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. The indicator face is divided into green (safe), yellow (caution) and red (danger) segments. Updates to the jet's design included a re-contoured leading edge to improve cruise performance, as well as higher ceiling capabilities of 51,000 feet and reduced runway length of 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. 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 Improved version. Some aircraft have a 1000 VA auxiliary inverter that is used as an option for added system capacity. 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. And best of all, I can place my Flight1 GTN combo in the VC panel with a super simple line change in the aircraft.cfg file. See their website at. In addition to the speed efficiency the 25G gained 370 nm in range compared to the normal 25D. One big problem it would not solve is the headroom and elbow room. hehehehe. 60 somethin gallon tank, 300nm+ range, I've stayed airborne for over 3 hours on one tank. The big news is that the decreased fuel consumption increases the range of the airplanes about 40 percent. A side benefit was the thicker wing section adds 15 square feet of wing area and allows for 81 more gallons of fuel. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. Nice touch. 2023 MOTORSPORT NETWORK. Dont forget to add you own person music files to the sound folder. The passenger compartment has the bench seat and two individual chairs arranged in club configuration. 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. Both military and civil versions, Blimps / Airships The inverter outputs are frequency synchronized through a paralleling bus tie. 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. Four additional shuttle valves connect the pneumatic system to the brake system for emergency braking. 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. This is really my only disappointment in the cockpit. Me, I would not touch a Lear 25 just because of age. . 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. What is missing in the Manual? Taxi operations are accomplished using the electronic nose wheel steering. The thrust reverser paddles are removable with a single click so we can see the partially hidden switches. When I asked, the developer about it, he agreed that Fuel Jettison would be a nice feature, but stated they have to draw the line someplace or they would never complete the package. Our large helicopter section. However, it has been often at the cost of fuel efficiency. 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 GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. You can also add EICAS gauges from the Lear 45 FSX/P3D default model. The PW JT15D-5 powers the Hawker 400XP with 3,400 lbst. Here is a recent price break down from Business and Corporate Aviation magazine. The pitch would be to corporate American and the world that the new Learjet was a safe and efficient means of doing business. You can find a series of great screenshots of the XP GLJ 25 SE in flight in our screenshot forum. The Models 35/36 and all the winglet models have much larger engines cowlings and a slightly longer fuselage than the Model 25D. The hydraulically retractable landing gear is of conventional tricycle configuration with air-hydraulic shock-type nose and main gear. Raisbeck Engineering has made a business of designing and marketing improvement to a large range of corporate aircraft. The panel has been cleaned up, regrouped and made somewhat prettier. It had the old Air Force engines on it. The 30 series have much more fuel efficient engines, not to mention quieter. Of all the models that you are likely to see in the skies that have the large wingtip fuel tanks the most numerous in descending order are: All the more recent models with larger wing area with winglets, longer and/or larger fuselages and larger diameter engines are: The grand total as of a few years ago was 2,330 Learjets of all models by all LearJet companies. You have to remember, VRSURGEON's mission is about 2.0 - 2.5 hours/ each leg for visiting family . 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. 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 vanes provide regulated voltage input to the angle-of-attack transducers, modified by a stall warning bias box to compensate for flap position. 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. Nose wheel steering is electrically controlled via the rudder pedals. This creates room for a big-airplane-type refreshment cabinet on the left side of the cabin. A 25 will burn more fuel, of course, but that's only part of the equation. The Model 35/36 would go on to sell an astounding 738 units. WebThe 25 seats up to 10 passengers plus 2 pilot (s).

On the same amount of fuel the Model 35 has a range of 2,630 nm against 1,621 for the Model 25B; the Model 36 endurance is 3,146 nm to 1,861 for the 25C. Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. There were several Model 25 Learjets starting with the basic or original Model 25 that was introduced as the Stretched or Long Range Learjet. Because this new release is specifically designed for newer PC and video cards, you can expect superior performance. I exchanged a few emails with the developer about the Empty Weight found in the aircraft.cfg file and therefore in the dropdown Fuel and Payload box. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. Lears made their mark with exceptional speed and high-level cruise. The Lear 45 is a "fresh sheet" Lear that is already in production. All three installers are included. 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. The Lear loves to be at FL400. Other than being thoroughly modern, one of the most requested features for FSX/P3D add ons nowadays is included the ability to place your Flight1 GTN 650/750 combo in the HD VC panel. Be careful though, and make sure you have a backup of your aircraft.cfg file and if you screw it up dont email the developer and ask for help. Every conversation stressed the Learjets FAR 25, Transport Category certification, the very same certification level as a Boeing 747. The spoilers provide an effective means of increasing normal rates of descent and may be used as a drag device to achieve rapid airspeed deceleration. 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. 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 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. When the angle-of-attack transducer vanes decrease below the stall point, the nose down command is removed. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. Hanger, insurance, service, unscheduled maintenance,de-icing, etc., you truly need to be prepared for the "real world" costs of ownership. The good news is that you can download some excellent training manuals that have color illustrations, full systems descriptions and the necessary performance charts specifically for the Model 24/25 Learjet not all of them but the full pack for Mach 0.77). The nose gear doors operate mechanically with linkages attached to the nose gear shock strut. Simply put, a shorter cabin to make room for more fuel. You can find that post in the screenshot forum. With practically identical cabins and cockpits, a million dollars would buy a lot of jet fuel or a lot of extra goodies for the panel. The Model 31A /ER was the long range version which added an additional 275 miles to the range. 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. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. 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. A pre-charged accumulator dampens and absorbs pressure surges. The company is careful to emphasize that the 35 and 36 are additions to the line and not replacements for the 24D, 25B and 25C. 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. WebThe 25 seats up to 10 passengers plus 2 pilot (s). I've never flown the Lears, but wouldn't an old 25 have a hard time with noise restrictions at most airports? ). It took a year or more to realize they really needed an updated Model 35A and an extended range Model 36A. These boundary layer energizers are small spanwise ridges on the upper wing surface just ahead of the aileron. 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. 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. That is really nice. Small stall strips were place on the leading edge with a newly designed stall fence. The Gates Rubber Company purchased all of Bill Lears interest for about $28 million in early 1967. The Model 25C also has an optional two bed sleeping compartment. 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. Aircraft painted in beautiful and original liveries, Airport Overviews Two wing tanks, a fuselage tank and two wing tip tanks. 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. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 A drag chute is fitted as optional equipment on some Learjet 25 aircraft.
