You will want to read the manual and maybe read the forums to become familiar with this early Automatic Flight Control System (AFCS). 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. They are practically identical to the engines in the supersonic T-38A Air Force jet that the Thunderbirds flew for years, except the civilian version does not have the afterburner. ) For these faults, I apologize. Say on a 1 hour flight. 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 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. 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. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. The chute offers an addition safety margin, since it can significantly reduce the stopping distance. You have to remember, VRSURGEON's mission is about 2.0 - 2.5 hours/ each leg for visiting family . There are more Learjets in service than any other business jet. Exactly which specific model is this Classic Learjet? The Model 25C also has an optional two bed sleeping compartment. This one got interrupted a couple of times and I feel guilty that it took me so long to finally complete the review. 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. A refrigeration-type cooling system is used for cooling and dehumidification while the aircraft is on the ground or operating at altitudes below 18 000 feet. You can also add EICAS gauges from the Lear 45 FSX/P3D default model. The Lear loves to be at FL400. A green overboard indicator on the outside surface of the dorsal fin will be ruptured or missing to indicate that the rupture disc is not intact. You need to factor in that at today's fuel price, you can pay anywhere from $3.75 to 8.50 per gallon of Jet A. The control wheels operate the elevator and ailerons mechanically through a system of cables, pulleys, push-pull tubes and bell cranks. Flying Magazine, June 1980. Here is a recent price break down from Business and Corporate Aviation magazine. 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. Approach reference speed was cut by 12 knots and the landing runway requirement was reduced by more than 800 feet. All rights reserved. Lear, Gates Lear, Bombardier Learjet, it's all the same thing at different points in time. Emergency extension can be accomplished pneumatically in case of hydraulic or electrical system failure. A fully outfitted and animated cabin in included with 70s style airwork. Click here for more information and to see all donations year to date. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. That all makes a big difference as to practicality, purpose, and just plain thrill factor! Your burn rate is probably 140-175 gal/ hour, depending on power settings. A used Lear @ $675,000USD will cost more than the savings on a PC-12 over the course of a year. 100 hours a year isn't worth owning an airplane. Pictures of great freighter aircraft, Government Aircraft This is not a problem in the real world cockpit but is a pain in most desktop simulator models. http://www.avsim.com/index.php/_/reviews/aircraft/review-learjet-24b-by-lionheart-creations-ltd-r2543, http://www.avsim.com/index.php/_/reviews/aircraft/review-a-comparison-of-2-jets-r2567. This added a stall strip and full-chord wing fence to create an aerodynamic warning and a straight-ahead stall. 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. In addition to the speed efficiency the 25G gained 370 nm in range compared to the normal 25D. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. To correct for the wing drop, in 1979 Gates introduced another improvement call Softflite. 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. Total Cost of Ownership: $700,646.69 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. Primary steering mode allows up to 45 degrees angle of turn and is suitable for slow speed aggressive steering maneuvers. All rights reserved. 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 angle-of-attack transducer vanes decrease below the stall point, the nose down command is removed. For some reason, this XP GLJ 25D SE has all the switches and lights but does not have the system coded. Two spherical fire extinguisher containers can discharge their contents to either engine. You need to be a member in order to leave a comment. Get my point? Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. 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. 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 tank cross-flow valve is installed to prevent fuel transfer between wing tanks. Ask the man who owns one Actually that bit of airport rumor comes via a PC-12 operator up here. 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. Each engine is rated at 2950 pounds of thrust at sea level. ( Aircraft painted in beautiful and original liveries, Airport Overviews You can only carry so much fuel and still have room for a few passengers. This is achieved by removing the starboard seating to allow for a stretcher, mounting oxygen bottles and intravenous drip equipment. 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 Engine bleed air is admitted through a flow control valve to a heat exchanger. One of the Learjet milestones was the delivery of the 500th Learjet, Learjet 25D on April 8, 1975 to the Mexican Navy. The autopilot head unit is mounted on the lower center console immediately below the Fuel Control Panel. Bottom Line: A most definite Buy Rating. 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. The average price of the Learjet 25D is not currently available. Intersting. It is possible for gravel from an improperly packed gravel runway to be sucked into the engines causing "foreign object damage", thus the need for the kit. 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. Four additional shuttle valves connect the pneumatic system to the brake system for emergency braking. In July, 2008 this same barrel of oil hit a new high of $147.27. A duty cycle of 3 minutes on and a cooling period of 20 minutes off is required to avoid overheating the pump motor. The steering system on aircraft without variable authority nose wheel steering requires the pilot to select master or primary steering mode. See cover of AW&ST, December 6, 1982. But, the good news is that you will be flying one of the fastest civilian airplanes in the sky. 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. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. This creates room for a big-airplane-type refreshment cabinet on the left side of the cabin. I decided on an Empty Weight of 7,168 pounds and a total fuel capacity of 1,055 gallons. 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 would solve all three disadvantages of the Model 25 Learjet. However, it has been often at the cost of fuel efficiency. The aircraft is equipped with AC (Alternating Current) and DC (Direct Current) electrical systems. 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. Tail and Winglet closeups with beautiful airline logos. A 25 will burn more fuel, of course, but that's only part of the equation. 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. Two disc-type indicators are flush mounted under the left engine. A bit of a misnomer, the Long Range should be taken with a grain of salt. 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. 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 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. The Sun visors do more than flip up or down. Remember, back at the time of production, the Model 25D was a full million dollars cheaper than a new Model 35. Of course, the Model 25 was an improvement of the Model 24 that had replaced the original Model 23 the one that started it all. Best Range: 1875 NM This is a review of the recently introduced Xtreme Prototypes Classic GLJ Model 25 Special Edition aircraft add on for FSX and P3D. Our large helicopter section. It had the old Air Force engines on it. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft 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 30 series have much more fuel efficient engines, not to mention quieter. This free Sample Version has more information in it than most developers provide for competing products. I tend you use the Honeywell name for the engines. The XP design team did a good job with what they had to work with. Hopefully Flysimware will tweak this accordingly. 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. I would like to recount the history of the General Electric CJ610 engine used in all the 20 series Learjet models, including our GLJ 25SE and hopefully get back to the story of how the original Garrett AiResearch TFE731 engine came to be. Simply put, a shorter cabin to make room for more fuel. The Go Around feature is especially well done, be sure to learn more about it. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. hmm. I just need to find the time to find all those 80 animations in the cockpit.

[2], Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on the aft fuselage. Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. Founder of AVSIM Online. In master mode, 10 degrees of steering is possible. You can use 15,300 pounds as ramp weight with a MTOW of 15,000 lbs. The lanyard is attached to the aircraft at the forward end of the tailcone access door opening. WebThe 25 seats up to 10 passengers plus 2 pilot (s). 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. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. Jump straight to the total cost table of the Bombardier Learjet 31. Improved version with greater fuel capacity. Every type from fighters to helicopters from air forces around the globe, Classic Airliners Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. Our Model selected for this review is in the center. 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. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. I've never flown the Lears, but wouldn't an old 25 have a hard time with noise restrictions at most airports? The two flight crew are then supplemented by either a doctor or flight nurse or both. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft A jet pump installed in each tip tank transfers fuel into the wing tanks. It's got autopilots that will do everything but put sugar in your coffee. The Learjet 25 cabin is pressurized to enable high altitude operations without the use of supplemental oxygen. Everything from the Goodyear blimp to the Zeppelin, Night Photos 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. We currently have 0 (new or used) Learjet 25D aircraft for sale. WebThe 25 seats up to 10 passengers plus 2 pilot (s). 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. Each system has a detailed description along with a key to every switch, gauge, and instrument. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. You can read those reviews here and here. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. Most Learjet 25 aircraft were fitted with a fuselage tank. 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. I did manage to only buy one pair of shoes, one add-on aircraft, and commit to only three more reviews.

A drag chute is fitted as optional equipment on some Learjet 25 aircraft. When the tank is full, a float switch de-energizes the wing boost pumps and closes the valve. Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). 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. - Features that would be useful to you. 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. 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 Gates Rubber Company purchased all of Bill Lears interest for about $28 million in early 1967. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). You know, that old just a few more lines of code, thing.. Typical Price: $2,296,212.00 Intersting. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs.

WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. Or possibly several hours away from a commercial field? 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. Neither was long range endurance it was pure speed and the ability to get over the weather that moved corporate aviation to the jets. 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. 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. One of our Planephd Experts will be in touch with you shortly. Over pressurization is prevented by a pressure relief valve which opens at 1700 psi. 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. Or you could always get a Notar. Both look like Learjets. The H-valve position can be adjusted by the crew to increase or reduce the amount of bleed air cooling at the heat exchanger. 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. Ouch. 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. 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. It would have been a wonderful addition if they had spent another day or so and added the climb, cruise, and descent details to the example. The Learjet 25 is listed explicitly. The Bombardier Learjet 60 can cruise at up to 51,000 feet. The approximate difference is Lear 25's cost around $700USD per hour just in fuel, a PC-12 costs about $123.50. 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. Even better would be a full-blown tutorial flight or example flight. Good luck. 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. I need something cabin class that is cheap to fly for about 1 hour legs. The Lear 60 is also still rolling down the line, and within weeks the "Continental" will roll out its first production aircraft. 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. 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. Credit: FROM THE OCTOBER 1973 BUSINESS & COMMERCIAL AVIATION. Jump straight to the total cost table of the Bombardier Learjet 31. Many don't put that on their FCar in decades. 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. The 30 series have much more fuel efficient engines, not to mention quieter. Oxygen is always available for the crew and can be made available to the passengers manually or automatically. I now have these items properly introduced and scheduled in my new more leisurely work schedule. Pretty heady stuff, this Century III wing mod. VRSURGEON also didn't state where his Family is, possibly not near a commercial field? New safety features were high on the priority list like the Century III wing design with SoftFlite to improve the low speed handling characteristics to appeal more to the general aviation corporate pilots and less to the ex-military trained corporate pilots. 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 25G was introduced in late 1980 mainly to set or break some speed records for publicity. The Garrett engines were designed to be fuel efficient, and quiet enough to meet present and future airport noise rules. 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 wonder why they decided to start with a new version 2.0? by the manufacturer or FAA. 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. Gates did not make any significant changes to the Model 25D because it was near the end of the design cycle for the highly inefficient fuel-guzzling GE turbojet engines and the short wings with the huge tip-tanks to carry the necessary fuel. 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. It only takes about 5 minutes to jettison the necessary fuel from the tip tanks, but it is so enjoyable. The Learjet 25 offers an ideal high speed platform for business travel for six to eight passengers. My screen images are not as sharp as it should be but, I just cant seem to find to time to tweak it. 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. The Learjet 25 also requires long runways at high altitude or ambient temperature. (But the cargo door is still available as an option.) Rest assured, the productionl ine is still rolling right along. They have their own book for the 30 series Learjets. During ground operations, a solenoid limits the pressure differential to 0.25 psi in order to ensure normal functioning of the door and emergency exit. 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. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Two motor-driven shutoff valves will stop hydraulic flow to the engine-driven pumps in case of an emergency. Both are powered by aft-fuselage-mounted, twin Honeywell TFE731-40BR turbofans, with a top speed of an impressive 535 mph (465 knots) and an average fuel burn of just under 200 gallons per hour. The Learjet 25D was first built in the mid-1970s but is still flying today. True! Understand that age equals maintenance because things wear out. Here is a recent price break down from Business and Corporate Aviation magazine. Some of the milestones credited to Gates leadership was actually accomplished prior to the Gates takeover. The leading edge now sweeps back to the extensions, then breaks forward and parallels the trailing edge. Interconnecting cables synchronize the flaps throughout their range of travel and a limit switch located on the left flap sector prevents over-travel.

The DC system is powered from two 28 Volt, 400 Amperes, engine-driven starter-generators. A pre-charged accumulator dampens and absorbs pressure surges. The Bombardier Learjet 60 can cruise at up to 51,000 feet. In cruise flight the Learjet flies at about a three-degrees nose-up angle so the engineers lowered the nose of the tip tanks three degrees. I forced myself to cut it short and I left out a lot of my research material. The Models 35/36 and all the winglet models have much larger engines cowlings and a slightly longer fuselage than the Model 25D. 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. 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. The pointer responds to the dynamic pressure from the pitot heads on the nose compartment.
