But, the standup and walk around Learjet cabin would arrive at a later date with the 40 and 60 series. 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. Oxygen is contained in a pressurized bottle located in the dorsal fin of the aircraft. The angle-of-attack transducer supplies a proportional voltage to the angle-of-attack of the aircraft. WebEvery Lear that comes out of the factory is equipped to fly itself. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. This pales in total numbers when compared to the Cessna Citation family of business jets that is more than 6,000 and counting. One of our Planephd Experts will be in touch with you shortly. 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. Todays price is more like $50.00 a barrel. Mainly because the two models were designed and built alongside each other and practically all the improvements being designed for the newer, slightly larger and better selling Model 35/36 were also being applied to the Model 25 provided it was cost efficient. Dont forget to add you own person music files to the sound folder. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). The nose wheel has a specially moulded tire to prevent water splashing into the engines. 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. Make sure you checkout the Approach plates and the iPad on the side panels. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. 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. A fully outfitted and animated cabin in included with 70s style airwork. You will find more and more nifty features designed into this add on as you spend more time flying. 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. FC-110 with Yaw Dampers. 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 40 is a 45 that has about 26 inches chopped out of the fuselagealso in production and certification with first flight scheduled for March. No extra charges for P3D. Two wing tanks, a fuselage tank and two wing tip tanks. The Bombardier Learjet 60 can cruise at up to 51,000 feet. Some better than others, but all much better than none. Two spherical fire extinguisher containers can discharge their contents to either engine. 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 thrust reverser paddles are removable with a single click so we can see the partially hidden switches. I have a fast PC with a 970 video card, I should have bought a 980, but didnt. 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. Here are some excerpts from the book The History of North American Small Gas Turbine Aircraft Engines, written by Richard A. Leyes and William A. Fleming, available for purchase at Google Books. In addition to the speed efficiency the 25G gained 370 nm in range compared to the normal 25D. FAA certified on September 4, 1970. Installation extra. Every type from fighters to helicopters from air forces around the globe, Classic Airliners 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. This would solve all three disadvantages of the Model 25 Learjet. 1. A 25 will burn more fuel, of course, but that's only part of the equation. See their website at. We thank you for your support and hope you'll join the largest aviation community on the web. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. The GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. See cover of AW&ST, December 6, 1982. A jet pump and electrical boost pump are mounted in each wing tank near the centre bulkhead to supply fuel under pressure to the respective engine fuel system. As the ignition cycle is completed, the igniter plugs cease sparking and combustion becomes self-sustaining. So, in summary, it appears that Gates was going down a path of basically adding two new engines and whatever electrical, mechanical, hydraulics-wise and otherwise was required to make them work on an existing well developed airplane to move from turbojet engines to fanjet engines. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. Here is a recent price break down from Business and Corporate Aviation magazine. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. Ouch. The lower console is now wider, not double wide, but somewhat wider. hehehehe. 60 somethin gallon tank, 300nm+ range, I've stayed airborne for over 3 hours on one tank. 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. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. The Model 25D will climb with bursts at 8,000 fpm and will climb from Sea Level to FL430 in 13 minutes. The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. 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. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. You can also add EICAS gauges from the Lear 45 FSX/P3D default model. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 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. That all makes a big difference as to practicality, purpose, and just plain thrill factor! 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. 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. The airplane had reportedly departed Belm, Brazil without a flight plan and with the transponder turned off. True! See this picture and article found in the June 23, 1969 edition of Aviation Week and Space Technology magazine. 47 The best glide distance with engines windmilling is obtained with a clean airplane configuration and with a glide speed of 160 to 170 knots. WebThe Learjet 25 generally has five fuel tanks. The XP GLJ-25SE does not identify the AP model number anyplace in the manual, but it is a probably model as a J.E.T. To demonstrate the how much the fuel those tip tanks hold, this is what can happen if a greenhorn fuel boy fills one wing with the other being empty. 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. It is very obvious to me that I only scratched the surface when describing the depth and details of many of the systems and procedures that can be simulated when flying this classic Lear 25D. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. 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. That could be said for ferrari ownership as well. 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. It took a year or more to realize they really needed an updated Model 35A and an extended range Model 36A. The Classic GLJ Model 25 SE runs smooth as butter on my test system. 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. Two disc-type indicators are flush mounted under the left engine. 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. 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. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. But first, they needed to stop the bleeding and improve the cash flow at their newly acquired Learjet factory. The 35 has a bench-style rear seat that will accommodate two wide bodies, or 3 very thin ones on short trips, four forward facing chairs and a side-facing potty/jump seat opposite the door. The Bombardier Learjet 31 can cruise at up to 51,000 feet. 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. Although Lear is saying the 35 and 36 have eight- and six-passenger cabins respectively, the arrangements theyre showing are really seven and four for practical purposes. . 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. Photo: Charlie Gates on left, Harry Combs on the right. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. This frequency is compared to a normal deceleration curve and if it deviates it activates a small torque motor in the affected wheel control valve which shunts braking pressure to the return line by means of a spool valve. You really need to do your self a favor, and go to your local private airport, find a Company that does Lear maintenance. The chute offers an addition safety margin, since it can significantly reduce the stopping distance. A side benefit was the thicker wing section adds 15 square feet of wing area and allows for 81 more gallons of fuel. Check column 5, for the 1,000 nm comparison of the fuel burn. I suggested the Empty Weight be reduced from 8,120 to 7,468 and the fuel load increased to 910 gallons. Interconnecting cables synchronize the flaps throughout their range of travel and a limit switch located on the left flap sector prevents over-travel. There are more Learjets in service than any other business jet. But, the good news is that you will be flying one of the fastest civilian airplanes in the sky. 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. 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. Two wing tanks, a fuselage tank and two wing tip tanks. Bottom Line: A most definite Buy Rating. The refrigeration system consists of a compressor, receiver dehydrator and evaporative cooler located above the baggage compartment. Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. This created a little unexpected legroom in the cabin, and they even gave the crew a few more inches. The Learjet 25 cabin is pressurized to enable high altitude operations without the use of supplemental oxygen. It only takes about 5 minutes to jettison the necessary fuel from the tip tanks, but it is so enjoyable.

Intersting. Improved version with greater fuel capacity. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft 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. AVSIM Online - Simming's Premier Resource! However, it has been often at the cost of fuel efficiency. 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 Only $1.1 MM for the full mod. WebEvery Lear that comes out of the factory is equipped to fly itself. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. 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. When the angle-of-attack transducer vanes decrease below the stall point, the nose down command is removed. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. You can use 15,300 pounds as ramp weight with a MTOW of 15,000 lbs. 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. This mode is suitable for straight taxi, takeoff and gentle turns. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. The cabin interior can be converted to several different configurations to allow for cargo and medevacs. I forced myself to cut it short and I left out a lot of my research material. The first Model 25 flew on August 12, 1966, and the first delivery was in November 1967.[1]. The Model 25 was introduced just prior to Gates taking over the majority ownership of Lear Jet in late 1966. When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. The cabin temperature is controlled by regulating the temperature of the pressure bleed air that is routed through the cabin. You need to be a member in order to leave a comment.

Nose wheel steering is electrically controlled via the rudder pedals. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. The fuselage tank can be filled by the wing boost pumps through the transfer line and the fuel transfer valve. You can find a series of great screenshots of the XP GLJ 25 SE in flight in our screenshot forum. They even had the engine model numbers and thrust level properly identified. In case you just skipped over the CJ610 engine history, the highlights are that every production Model 20 series was powered by some version of the GE CJ610-1 through the CJ610-8A turbojet engine rated at 2,850 or 2,950 lbst. Good luck. Both pilots died. If it floats or flies rent it. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. It is a stretched version of the Learjet 24. Most charge anywhere from $1200 to $1800 and hour for these birds. Simply put, a shorter cabin to make room for more fuel. The 30 series have much more fuel efficient engines, not to mention quieter. Just so you know the details Timberland shoes, Flysimware Learjet 35, SPAD.next, Volair Avionics Panel, and the new Aerofly FS2 simulator. These boundary layer energizers are small spanwise ridges on the upper wing surface just ahead of the aileron. These two important reasons are near the top of the priority list, but the fact that most everyone was convinced that taming the noise levels of this military adapted gas guzzling high performance turbojet engine was going to be near impossible. 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. We all know the LearJet has gone through several iterations by 3 primary aircraft companies. The valves are controlled by the FIRE switch and activation of these valves are indicated with pinhead lights located in the cockpit next to the FIRE switch. It's got autopilots that will do everything but put sugar in your coffee. Pictures of great freighter aircraft, Government Aircraft WebThe Learjet 25 generally has five fuel tanks. I use the following for my personal flying in the flight sims. The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). - Send us pictures of your plane. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. I've never flown the Lears, but wouldn't an old 25 have a hard time with noise restrictions at most airports?

If utilization is 100 hours per year, that's about 20 trips a year. 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. Most Learjet 25 aircraft were fitted with a fuselage tank. Some were very popular and others were just bad timing or too expensive to justify. A duty cycle of 3 minutes on and a cooling period of 20 minutes off is required to avoid overheating the pump motor. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. 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. 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.

A drag chute is fitted as optional equipment on some Learjet 25 aircraft. As strong as that 8 spar wing might be, when you put more than a ton of weight on the wingtips and then land a little hard with a 7 ton airplane moving at 120 knots or so, something is most likely going to break and when it does it is very flammable. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. Tips and recommended settings for beginners are included but so the seasoned pilots that want to get up and flying quickly Alain has included a separate 2-page Quick Start. The Bombardier Learjet 31 can cruise at up to 51,000 feet. Dial markings are based on percent of maximum allowable engine speed. 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. Typical cruising altitudes are between Flight Level 390 and Flight Level 430 which means the Learjet 25 is capable of overflying most weather systems and congested airspace. I decided on an Empty Weight of 7,168 pounds and a total fuel capacity of 1,055 gallons. Taxi operations are accomplished using the electronic nose wheel steering. The largest seller is the Model 25, but more 35s were sold in the past six years. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Due to the many buyouts, mergers and takeovers, Garrett engines may be referred using the original name Garrett AiResearch, or AlliedSignal, or Honeywell. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. The main gear has dual wheels and brakes on each strut. Improved version. 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 Lear loves to be at FL400. 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. The engineers have effectively picked up another foot of cabin room by switching to a narrower, people-sized cabin door in place of the old cargo-width entrance. Flight planning or any other aircraft operations should only be done using official technical information provided The Lear loves to be at FL400. The original model 25 wing had a fairly sharp leading edge designed for high-speed cruise. Me, I would not touch a Lear 25 just because of age. Not only the F1 GTN but you can also have your working REX/Milviz Advantage weather radar. In master mode, 10 degrees of steering is possible. I was not able to tell for sure if the Century III wing mod was designed into our model, but the VR, VREF and runway requirements should tell the story. Photos: Original Model 23 (at Smithsonian) on left, yet to be built Model 85 on right. A bit of a misnomer, the Long Range should be taken with a grain of salt. - Aircraft data that you believe is inaccurate or have specific experiences. The leading edge of the standard wing sweeps back at a 13-degree angle to a straight trailing edge. Engine bleed air is admitted through a flow control valve to a heat exchanger. Had they continued the sweep they would have run out of wing-tip chord and structure upon which to mound the tip tanks, or they would have had to move the tanks back, thus aggravating the cg problem. The Bombardier Learjet 60 can cruise at up to 51,000 feet. After a honest introduction to the turbine world, will you feel that playing with Ferrari's are chump change, by comparison. 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). Leasedont buy. 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. Beautiful shots taken while the sun is below the horizon, Accidents With a cruising speed of approximately Mach 0.76, passengers reach their destination in good time. The Model 35/36 would go on to sell an astounding 738 units. The Learjet 25 also requires long runways at high altitude or ambient temperature. The ICAO designator as used in flight plans for all Learjet 25 models is LJ25. They have their own book for the 30 series Learjets. Things seem to be just fine at the Lear jet factory. Back in the real early days, fuel efficiency wasnt a big concern mainly because jet fuel only cost 18 20 cents a gallon. So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. I am getting a little lazy in my old age so I am going to paste the GE engine history here in lieu of typing it from scratch. A jet pump installed in each tip tank transfers fuel into the wing tanks. 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. However, it has been often at the cost of fuel efficiency. Part of MOTORSPORT NETWORK. All rights reserved. 340 Tail and Winglet closeups with beautiful airline logos.
