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. Gates thought a replacement for these late model 20 series jets should be fairly straight forward and they managed a great replacement with the introduction of the Gates Learjet Model 35. 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. All rights reserved. What is missing in the Manual? 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. Both military and civil versions, Blimps / Airships I like this Classic Learjet a lot. What about a King Air 90 or Cessna 421? The pitch would be to corporate American and the world that the new Learjet was a safe and efficient means of doing business. 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 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. These are intended for training real world pilots and is a free download until the link is removed or broken. Typical Price: $2,296,212.00 In 1970 the Learjet 25B was produced along with the Learjet 25C in the same year. The Bombardier Learjet 31 can cruise at up to 51,000 feet. 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. 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. Tom Allensworth, A bit of a misnomer, the Long Range should be taken with a grain of salt. 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. Now, it is loaded, maybe overloaded, with takeoff and landing calculation charts, tables and data. 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 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. 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. Emergency extension can be accomplished pneumatically in case of hydraulic or electrical system failure. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. I tend you use the Honeywell name for the engines. But, there's nothing like giving the " finger" to the commercial flying world! Many consider the Model 31A the best of the 30 series and even the best flying Learjet of all small fuselage models. 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 The Bombardier Learjet 45XR can cruise at up to 51,000 feet. Two motor-driven shutoff valves will stop hydraulic flow to the engine-driven pumps in case of an emergency. Just remember that it all starts with the Altitude Pre-selector and it is a lot easier if you have the airplane already at the correct airspeed and in the proper climb or descent attitude when the AP is engaged. The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). 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. March 28, 1980 - Gates Learjet flies high with its one-thousandth sale. They put out 18.6 percent more thrust at sea level than the GE CJ610s used on the Model 25, and nine percent more thrust at 40,000 feet. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes The brake system utilizes hydraulic pressure for power boost. hehehehe. 60 somethin gallon tank, 300nm+ range, I've stayed airborne for over 3 hours on one tank. Two wing tanks, a fuselage tank and two wing tip tanks. 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. [2], Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on the aft fuselage. 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. 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. Sure, there were some additional company names involved, but we can narrow it down to Bill Lears Lear Jet, Charlie Gates Learjet, and Bombardiers Learjet designs. It only takes about 5 minutes to jettison the necessary fuel from the tip tanks, but it is so enjoyable. Every type from fighters to helicopters from air forces around the globe, Classic Airliners This increased weight is significant because the additional 710 pounds aft gave Gates engineers a real cg problem that precluded a simple change of engines on the Model 25, as the original plan intended. Understand that age equals maintenance because things wear out. Two shuttle valves in the pressure lines prevent fluid feedback between the pilot's and copilot's pedals. A duty cycle of 3 minutes on and a cooling period of 20 minutes off is required to avoid overheating the pump motor. 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 If you can't afford a used PC-12 you can't afford a flight department to run it. autopilot. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. - Aircraft specific reviews and articles. High Speed Cruise 475 kts The Model 31A /ER was the long range version which added an additional 275 miles to the range. The Learjet 25 cabin is pressurized to enable high altitude operations without the use of supplemental oxygen. This has always been a choke point, restricting airflow and creating drag at high speed. I get frustrated with the older autopilots but they usually do what they were designed to do. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. The fuel inefficiency, the limited range, and the airport noise problem. 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. Microsofts planned layoffs will hurt MSFS or not? 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 30 series have much more fuel efficient engines, not to mention quieter. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. 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. Search for the string learjet 24/25 MrMoo pdf. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. With a cruising speed of approximately Mach 0.76, passengers reach their destination in good time. ( 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. 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. 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. I now have these items properly introduced and scheduled in my new more leisurely work schedule. The 51,000 feet altitude Certification was added for all 25D/F models, although the specs are a little vague in the XO manual. 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. Starting ignition is provided by a dual output capacitor-discharge system. Evidently this was sound planning because at the end of production, the 30 series, small fuselage, Garrett powered models accounted to just shy of a thousand airplanes delivered to happy Learjet customers. A jet pump installed in each tip tank transfers fuel into the wing tanks. The future of corporate jet travel was going to require more seats, more efficient engines, and decent cabin headroom. 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. Has anyone heard of Learjet proposing to make a new lear? A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. Hopefully Flysimware will tweak this accordingly. One of our Planephd Experts will be in touch with you shortly. 2023 MOTORSPORT NETWORK. Ask the man who owns one Actually that bit of airport rumor comes via a PC-12 operator up here. Bottom Line: A most definite Buy Rating. The chute offers an addition safety margin, since it can significantly reduce the stopping distance. At high cruise speeds, they delay the onset of turbulent flow over the ailerons more effectively than the vortex generators and create less drag. - Send us pictures of your plane. 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 Quote: When I finally got the cabin worked out, I damn near shot myselfnot enough room. 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. Hopefully Flysimware will tweak this accordingly. 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 GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. A 25 will burn more fuel, of course, but that's only part of the equation. 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. 2023 GlobalAir.com. To overcome the problem, they added 13 inches to the fuselage ahead of the wings leading edge. 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. Ouch. 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. On aircraft equipped with variable authority steering, the steering authority varies with ground speed. FAA certified on September 4, 1970. This creates room for one or dual INS control heads, which are necessary in these Lears since either of them has the range to pop over to Europe and on down into Africa or the Orient. Back in the real early days, fuel efficiency wasnt a big concern mainly because jet fuel only cost 18 20 cents a gallon. This creates room for a big-airplane-type refreshment cabinet on the left side of the cabin. 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. 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. 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. Engine bleed air is admitted through a flow control valve to a heat exchanger. The main gear has dual wheels and brakes on each strut. 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. The hot section on a PC-12 is the same as one engine of a King Air 300, just a little more than one on a King Air 200. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. You will want to read the manual and maybe read the forums to become familiar with this early Automatic Flight Control System (AFCS). So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. There were several Model 25 Learjets starting with the basic or original Model 25 that was introduced as the Stretched or Long Range Learjet. Raisbeck Engineering has made a business of designing and marketing improvement to a large range of corporate aircraft. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. This created a little unexpected legroom in the cabin, and they even gave the crew a few more inches. You have to remember, VRSURGEON's mission is about 2.0 - 2.5 hours/ each leg for visiting family . L-188, this rumor comes from a PC-12 operator up here, namely me. Not only the F1 GTN but you can also have your working REX/Milviz Advantage weather radar. You will find more and more nifty features designed into this add on as you spend more time flying. This Century III modification formed a constant radius curve that significantly lowered the stall speed of the Lear 25D but just as important, it cut the rotation speed by 14 knots and shortened the takeoff runway requirement by more than a 1,000 feet. Most charge anywhere from $1200 to $1800 and hour for these birds. The use of oxygen is only required for emergency in case of depressurization of the cabin or contamination of the cabin air. Unfortunately, this is not quite sufficient but, will eliminate the earlier Model 23 (large oval window) and the Model 24 (2 windows) and all the more recent follow-on models with winglets in lieu of the large wingtip tanks, except the Models 35/36 that are easily confused with the Model 25D. This is a very handy feature. As the wheel rotation speed accelerates to normal tolerance limits, normal braking pressure is restored. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. Both pilots died. FC-110 with Yaw Dampers. Two wing tanks, a fuselage tank and two wing tip tanks. Some were very popular and others were just bad timing or too expensive to justify. On aircraft equipped with an auxiliary hydraulic pump, the hydraulic pump switch located at the lower centre of the instrument panel activates the auxiliary hydraulic pump to provide in-flight standby hydraulic pressure. This doesnt raise the cruise speed Mach limits but does provide a greater safety margin in turbulence or when maneuvering at high speeds. It's got autopilots that will do everything but put sugar in your coffee. 100 hours a year isn't worth owning an airplane. No extra charges for P3D. See this picture and article found in the June 23, 1969 edition of Aviation Week and Space Technology magazine. 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. 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. The passenger compartment has the bench seat and two individual chairs arranged in club configuration. How about time to climb to 15,000 meters (just shy of 51,000 feet) in 12 minutes, 27 seconds? A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. . My screen images are not as sharp as it should be but, I just cant seem to find to time to tweak it. FerrariChat.com has no association with Ferrari S.p.A. 2023 FerrariChat. This would solve all three disadvantages of the Model 25 Learjet. 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. ). Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. 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. 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. Things seem to be just fine at the Lear jet factory. The fuel flow through a rotor-turbine at each engine causes the rotor to spin and a pickup coil emits pulses as the rotor blades pass through the coil field. WebThe Learjet 25 generally has five fuel tanks. The 30 series have much more fuel efficient engines, not to mention quieter. Two wing tanks, a fuselage tank and two wing tip tanks. 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. Here is a recent price break down from Business and Corporate Aviation magazine. - Features that would be useful to you. Discussion in 'Aviation Chat' started by vrsurgeon, Aug 3, 2012. When the angle-of-attack transducer vanes decrease below the stall point, the nose down command is removed. I have a fast PC with a 970 video card, I should have bought a 980, but didnt. Lear never used an A designator for any production Model 25, only on the Model 24. But first, they needed to stop the bleeding and improve the cash flow at their newly acquired Learjet factory. Not to mention the ability to file a flight plan, and go on a moment's notice. 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. We thank you for your support and hope you'll join the largest aviation community on the web. WebThe 25 seats up to 10 passengers plus 2 pilot (s). 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. Embraer is the latest manufacturer entering the business jet market with the Phenom and Legacy lines of business jets. 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 WebEvery Lear that comes out of the factory is equipped to fly itself. 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 Just so you know the details Timberland shoes, Flysimware Learjet 35, SPAD.next, Volair Avionics Panel, and the new Aerofly FS2 simulator. Some aircraft have a 1000 VA auxiliary inverter that is used as an option for added system capacity. Type development continued with the Models 25D and 25G, which included more advanced CJ610-8A engines and a ceiling increase to 51,000 feet. 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. The pointer responds to the dynamic pressure from the pitot heads on the nose compartment. I have been told that to do a hot section on the engine in a PC-12 costs about the same as getting both sides of a King Air done. Twin engine turbojet aircraft. 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. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. 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. 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. The Gates Rubber Company purchased all of Bill Lears interest for about $28 million in early 1967. Many don't put that on their FCar in decades. Long Range Cruise Speed 418 kts, Rate of climb 6,050 fpm, one engine ROC 1,910 fpm. See cover of AW&ST, December 6, 1982. The DC system is powered from two 28 Volt, 400 Amperes, engine-driven starter-generators. - Use this form or email to reach out to us: feedback@planephd.com. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. Actually Bill Lear himself summed it up nicely. I took it one step further for my personal flying and in effect made an XR version for a little Extra Range. 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. Two disc-type indicators are flush mounted under the left engine. The Model 36A is identical to the 35A with the exception of the larger fuselage fuel tank and the necessary reduction in fuselage seats and baggage area to make room for the extra fuel. Due to the ease of converting the cabin the Learjet 25 has found a niche as a medevac aircraft. We all know the LearJet has gone through several iterations by 3 primary aircraft companies. It is a stretched version of the Learjet 24. Just to whet your appetite, I have a few closeup screenshots to show some of the HD detail. 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. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. In master mode, 10 degrees of steering is possible. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. You can also add EICAS gauges from the Lear 45 FSX/P3D default model. The Model 28 had the same fuselage and engines at the Model 25D but, totally different high aspect ratio wings, larger wing surface area and the first winglets for a production business jet. Heck, if Learjet can do it, why cant we. Hence, the reduced Max Landing Weight. 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. Intersting. Installation extra. 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 angle-of-attack indicator translates signals from the stall warning system into visual indications of the aircraft angle-of-attack and allows the crew to monitor the proximity of stall caution zone. 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.
