Other than a few improvements in avionics, tires, adding anti-skid brakes, and fuel dump valves in the tip tanks, and introducing single point refueling, most of the later model 20 series Learjets were simply trading passenger seats for larger fuel tanks or vice versa. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. 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. Hopefully Flysimware will tweak this accordingly. A bit of a misnomer, the Long Range should be taken with a grain of salt. 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. The Lear 45 is a "fresh sheet" Lear that is already in production. - Features that would be useful to you. This free Sample Version has more information in it than most developers provide for competing products. This is from the XP Flight Manual. Everything from the Goodyear blimp to the Zeppelin, Night Photos The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. It is our mission to be the go to leaders in the aviation industry. 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. Photo: Charlie Gates on left, Harry Combs on the right. Let's not even talk about the cost in maintenance on a 30 year old plane. These numbers were soon eclipsed by Cessna and their Citation line of business jets. 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. The big news is that the decreased fuel consumption increases the range of the airplanes about 40 percent. This Century III wing did not alter the Learjets tendency to roll off sharply during a stall. Intersting. Both stories are somewhat amazing to me. I like this Classic Learjet a lot. Make sure you checkout the Approach plates and the iPad on the side panels. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. The ICAO designator as used in flight plans for all Learjet 25 models is LJ25. To correct for the wing drop, in 1979 Gates introduced another improvement call Softflite. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. Thanks to Alain Rouleau at xtremePrototypes.com for answering all my questions and providing the evaluation software. Due to the ease of converting the cabin the Learjet 25 has found a niche as a medevac aircraft. Two wing tanks, a fuselage tank and two wing tip tanks. Best Cruise: 417 KIAS 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 original tips were aligned with the longitudinal axis. Approach reference speed was cut by 12 knots and the landing runway requirement was reduced by more than 800 feet. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. The oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. To overcome the problem, they added 13 inches to the fuselage ahead of the wings leading edge. I wonder why they decided to start with a new version 2.0? This was done with a two-foot extension on each tip. They have their own book for the 30 series Learjets. Leasedont buy. The cabin pressure is provided by the conditioned air entering the cabin through the distribution ducts and controlled by modulating the amount of air exhausted from the cabin. It is easy to see why the turbojet was on the top of the list for replacement with fuel prices skyrocketing. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). 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 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, The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). That's a ton of Family! The Bombardier Learjet 31 can cruise at up to 51,000 feet. Not only the F1 GTN but you can also have your working REX/Milviz Advantage weather radar. I decided on an Empty Weight of 7,168 pounds and a total fuel capacity of 1,055 gallons. The main gear is enclosed by two doors after retraction. 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 XP design team did a good job with what they had to work with. Many don't put that on their FCar in decades. 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. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. The closer you zoom in to the panel to more you appreciate just how well these new 3D gauges are performing super sharp image for my old eyes. 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. One big problem it would not solve is the headroom and elbow room. The pointer responds to the dynamic pressure from the pitot heads on the nose compartment. One summary table for fuel burn (1st hour, 2nd hour, etc) is included and a simplified example of a 950 nm flight is included which is more than most other developers include so I may be coming down a little hard on them. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. Beautiful shots taken while the sun is below the horizon, Accidents The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. The 30 series have much more fuel efficient engines, not to mention quieter. 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. Time to Look at the Excellent Flight Manual. It is tough to click on a button with a mouse or press and hold a switch for temporary changes in the flight path while also keeping a hand on a joy stick or simulator yoke. The Learjet 25 also requires long runways at high altitude or ambient temperature. They can walk you thru the service cost aspect of a Lear. For these faults, I apologize. What about a King Air 90 or Cessna 421? 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. The main gear has dual wheels and brakes on each strut. Rest assured, the productionl ine is still rolling right along. All rights reserved. Jump straight to the total cost table of the Bombardier Learjet 31. However, it has been often at the cost of fuel efficiency. The future of corporate jet travel was going to require more seats, more efficient engines, and decent cabin headroom. If you can't afford a used PC-12 you can't afford a flight department to run it. [1], Data from Jane's All The World's Aircraft 197677[11], Learjet 25B/25C Pilot's Manual, Gates Learjet Corporation, Wichita, Kansas, 1971, Learn how and when to remove this template message, "For many models, market hitting the apex", Information page from Aviation Safety Network, "Aviation Safety Network Accident Description - 2 March 1996", "Plane of singer Jenni Rivera missing in Mexico. See their website at. The airplane had reportedly departed Belm, Brazil without a flight plan and with the transponder turned off. 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 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. So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. The rudder pedals mechanically operate the rudder for directional yaw control. The indicator face is divided into green (safe), yellow (caution) and red (danger) segments. 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. One of the Learjet milestones was the delivery of the 500th Learjet, Learjet 25D on April 8, 1975 to the Mexican Navy. We currently have 0 (new or used) Learjet 25D aircraft for sale. In master mode, 10 degrees of steering is possible. 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. 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. 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. The Learjet 25D was first built in the mid-1970s but is still flying today. Improved version. The stall warning system utilizes a stall warning vane on each side of the nose. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. 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. 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. 47 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. As the ignition cycle is completed, the igniter plugs cease sparking and combustion becomes self-sustaining. The Bombardier Learjet 60 can cruise at up to 51,000 feet. A pre-charged accumulator dampens and absorbs pressure surges. Pictures of great freighter aircraft, Government Aircraft WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. Lears made their mark with exceptional speed and high-level cruise. 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. Our GLJ 25SE flight model does indeed have the updated BLEs instead of the older vortex generators. WebThe Learjet 25 generally has five fuel tanks. Please send us your experiences on your aircraft. The refrigeration system consists of a compressor, receiver dehydrator and evaporative cooler located above the baggage compartment. Back in the real early days, fuel efficiency wasnt a big concern mainly because jet fuel only cost 18 20 cents a gallon. 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. See this picture and article found in the June 23, 1969 edition of Aviation Week and Space Technology magazine. Click here for more information and to see all donations year to date. 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. The brake system utilizes hydraulic pressure for power boost. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. 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. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. But, the good news is that you will be flying one of the fastest civilian airplanes in the sky. 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, The Model 25 was introduced just prior to Gates taking over the majority ownership of Lear Jet in late 1966. Good luck. Photo: A Gates Learjet showing enormous size of fanjet engines. The first modification to the original Learjet wing came in 1970 when the tip tanks were realigned. This point is near the aircraft centre of gravity and minimizes weathervaning when the chute is deployed under crosswind conditions. 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. So, 10 percent of this essay, is "Review", and 90 percent about the history of the Learjet ? If it floats or flies rent it. 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 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. 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. If there was to be a Model 26, it would have most likely been powered by Garrett fanjet engines. 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. It is not perfect but any glitches or limitations are prominently discussed in the 160 page Flying Manual with suggestions for workarounds and hints on how to avoid any limitations of the simulators. Me, I would not touch a Lear 25 just because of age. Alain Rouleau at Xtreme Prototypes is known for his excellent flight manuals and this one ranks right up there at the top of this list. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. Tail and Winglet closeups with beautiful airline logos. The original model 25 wing had a fairly sharp leading edge designed for high-speed cruise. The Phenom 300 is marketed as direct competition of the smaller Bombardier Learjets and Citation CJ3/CJ4. This material was mainly about the influence the late model 25 and 28 Lears had on the follow on models mostly the 30 series and to Longhorn 55. The Learjet 25 is listed explicitly. 1. We all know the LearJet has gone through several iterations by 3 primary aircraft companies. 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 Learjet 25 cabin is pressurized to enable high altitude operations without the use of supplemental oxygen. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. A jet pump installed in each tip tank transfers fuel into the wing tanks.

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. Fuelburn: 149.0 GPH 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. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. 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. The electrically operated RPM tachometer consists of a signal generator on the engine and an indicator located in the centre of the instrument panel. 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. 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. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. The force applied in the nose down direction is 80 pounds at the control wheel. Aircraft painted in beautiful and original liveries, Airport Overviews Now, that would be ideal, maybe even make a video. Some were very popular and others were just bad timing or too expensive to justify. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. 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. Twin engine turbojet aircraft. 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. In addition to doing more work on less kerosene, the Garrett TFE 731s are 11 inches larger in diameter (to accommodate the 2.82 bypass-ratio fan) but, weigh almost twice as much as the engines they replace (747 pounds to 392). 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. 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. 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. One click on the 8-Track tape player will start, move to the next selection, or stop the music. I even like the default EICAS panel feature because I am only one click away from having the GTNs or weather radar in the panel. By the Numbers Recent Learjet sales is a very weak third place behind Cessna and Embraer. In order to minimize heat build-up in the brakes and reduce brake wear, pilots are advised to deploy the spoilers upon touchdown. 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. The chute offers an addition safety margin, since it can significantly reduce the stopping distance. Some of this research was done for the Lionheart LR24B review and the follow-on comparison of the Learjet 24B to the T-38. Meanwhile, we now have an up-to-date, high performance, high definition, highly accurate representation of a classic early LearJet designed for our modern PC and video cards for both FSX and P3D. 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 excellent throttle response enables rapid acceleration and precise power settings. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. 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 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. They even had the engine model numbers and thrust level properly identified. For some reason, this XP GLJ 25D SE has all the switches and lights but does not have the system coded. 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. 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. 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 Model 25C also has an optional two bed sleeping compartment. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. You can read those reviews here and here. Near the back of the flight manual is a full page Limitations with all the V speeds and Placard speeds. 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. This was caused by the weight of all that fuel in the tip tanks. On April 10, 2014, a privately owned Learjet 25D was destroyed on the ground by Venezuelan forces. 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. Tom Allensworth, 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. Nose wheel steering is electrically controlled via the rudder pedals. Learjet Model 35/36 677 total built (including 80 USAF C-21A), Learjet Model 60 323 + built (in production, Learjet Model 45 300 + built (in production), Learjet Model 40 90 + built (in production), Learjet Model 70/75 75 total built (in production). True! Now about that General Electric CJ610 turbojet engine. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft You can only carry so much fuel and still have room for a few passengers. 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. Introduced September 23, 1980. 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. we might get it one day down the road. Aircraft flying government officials, Helicopters Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. When designing a new engine, they could add enough thrust to overcome the additional weight required to carry more fuel in more tanks, in this case only larger fuselage tanks to make a truly intercontinental range Learjet. But, there's nothing like giving the " finger" to the commercial flying world! A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. 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, Fuel flow is indicated via a fuel flow system. Now, that is a really small diameter fuselage. So why are we talking about the Model 35/36 in a review of the Model 25D? - Send us pictures of your plane. The first Model 25 flew on August 12, 1966, and the first delivery was in November 1967.[1]. Improved version with greater fuel capacity. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. I'm not trying to dissuade you, just make you understand the JOYS of ownership!
