It is a stretched version of the Learjet 24. 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. 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. No warranty of 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. FAA certified on September 4, 1970. 340 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. 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. Thanks for the info..that was a great help? One of our Planephd Experts will be in touch with you shortly. - Use this form or email to reach out to us: feedback@planephd.com. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. Leasedont buy. Everything from the Goodyear blimp to the Zeppelin, Night Photos Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). I think the upper level VMO is actually 350 kts, provided it has the Century III wing. If utilization is 100 hours per year, that's about 20 trips a year. There was never a 25E model, but there was a 25F that was grouped in with the 25D production numbers. Some of this research was done for the Lionheart LR24B review and the follow-on comparison of the Learjet 24B to the T-38. The DC system is powered from two 28 Volt, 400 Amperes, engine-driven starter-generators. The Mode Selection switches, Altitude Pre-selector, and AP Vertical Speed Selector are mounted helter-skelter, just as the real world classic Learjets. I use the following for my personal flying in the flight sims. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. Two wing tanks, a fuselage tank and two wing tip tanks. A 25 will burn more fuel, of course, but that's only part of the equation. A new cuff was designed to accelerate the air movement in this area that smoothed the flow between the engine nacelle and the wings trailing edge. The Model 25D will climb with bursts at 8,000 fpm and will climb from Sea Level to FL430 in 13 minutes. To overcome the problem, they added 13 inches to the fuselage ahead of the wings leading edge. Views from inside the cockpit, Aircraft Cabins This created a little unexpected legroom in the cabin, and they even gave the crew a few more inches. Oops. 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. Exactly which specific model is this Classic Learjet? 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. Even with a 35 look for as new as you can afford. The 30 series have much more fuel efficient engines, not to mention quieter. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. One big problem it would not solve is the headroom and elbow room. 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. A drag chute is fitted as optional equipment on some Learjet 25 aircraft. 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. The Model 31/31A would be the final adaptation of the small bore fuselage but add large delta fins at the rear for yaw control and added 4 foot extensions to each wing with 4 foot high winglets for improved efficiencies and more docile handling. I suggested the Empty Weight be reduced from 8,120 to 7,468 and the fuel load increased to 910 gallons. 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. You can read those reviews here and here. That all makes a big difference as to practicality, purpose, and just plain thrill factor! Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. They have their own book for the 30 series Learjets. FC-110 with Yaw Dampers. 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. Now, that would be ideal, maybe even make a video. The aircraft description and specifications section, instrument panels, systems description have their one chapter or section along with a an excellent flight planning chapter. 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. This is from the XP Flight Manual. Just to whet your appetite, I have a few closeup screenshots to show some of the HD detail. 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 at the Lear factory in Wichita about a month ago. 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. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. A check valve prevents reverse flow between the containers. I just need to find the time to find all those 80 animations in the cockpit. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. 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. Approach reference speed was cut by 12 knots and the landing runway requirement was reduced by more than 800 feet. Hanger, insurance, service, unscheduled maintenance,de-icing, etc., you truly need to be prepared for the "real world" costs of ownership. 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. What is not shown in the accompanying artists sketch is just how large those new Garrett engines would be, or the fuselage stretch, or the increased wing span with that now familiar looking two foot section added out near the tips. Learn about cockpit equipment upgrades that are FAA mandated. ( The Model 35/36 would go on to sell an astounding 738 units. As good and as detailed and as beautiful as this GLJ Model 25s flight manual may be there is still room for improvement. 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. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Coupled approaches work very well and the integration of the GPS and GTNs is excellent. Neither was long range endurance it was pure speed and the ability to get over the weather that moved corporate aviation to the jets. 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 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. 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, Me, I would not touch a Lear 25 just because of age. Now, it is loaded, maybe overloaded, with takeoff and landing calculation charts, tables and data. Flying yourself's a beautiful thing! Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. Or you could always get a Notar. In addition to the speed efficiency the 25G gained 370 nm in range compared to the normal 25D. The 1,500th Learjet was delivered in June, 1986. Introduced September 23, 1980. 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. The Lear 60 is also still rolling down the line, and within weeks the "Continental" will roll out its first production aircraft. Fair enough. The GE CJ610-8A engines came directly from the military inventory. They also make good use of tooltips that a useful description of the selected device, not just what it is. Taxi operations are accomplished using the electronic nose wheel steering. Selected information from the www.Xtremeprototypes.com website. Get my point? A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. There were only a handful of 20 series models after the 25D. I like this Classic Learjet a lot. If it floats or flies rent it. See cover of AW&ST, December 6, 1982. 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. Thanks to Alain Rouleau at xtremePrototypes.com for answering all my questions and providing the evaluation software. - Send us pictures of your plane. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. The vortex generators, those rows of little metal tabs, and small fences were replaced with newly designed cuffs for the wingtip fins and Boundary Layer Energizers, BLEs. Improved version. The company is careful to emphasize that the 35 and 36 are additions to the line and not replacements for the 24D, 25B and 25C. But, the good news is that you will be flying one of the fastest civilian airplanes in the sky. I am in the business.been flipping large commercial jets to airlines for 15 years. As most of you already know, Bill Lear invented the autopilot during World War II, and every Learjet that ever left the factory came with a Bill Lear designed J.E.T. The CJ610-6 engines fitted to the Learjet 25 have very low inertia and accelerate rapidly. 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. Jump straight to the total cost table of the Bombardier Learjet 31. The Model 25C also has an optional two bed sleeping compartment. The hydraulically retractable landing gear is of conventional tricycle configuration with air-hydraulic shock-type nose and main gear. Total Cost of Ownership: $700,646.69 The Bombardier Learjet 45XR can cruise at up to 51,000 feet. 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. 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. This is not a problem in the real world cockpit but is a pain in most desktop simulator models. Despite being used at lower altitudes and equipped with small landing gear, the Learjet can land on gravel runways if it is fitted with a special "gravel kit". 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. 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. The pitch would be to corporate American and the world that the new Learjet was a safe and efficient means of doing business. FAA certified on September 4, 1970. Its amusing to speculate on the problems this much have given the engineers. I was disappointed that the developer did not include any climb, descent, or cruise performance charts in the Flight Planning section. 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. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. 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. 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 Century III wing modification alone lowered the final approach speed by an astounding 15% without any loss of cruise speed while reducing the landing distance by nearly 1,000 feet for the new Model 35. Raisbeck Engineering has made a business of designing and marketing improvement to a large range of corporate aircraft. Nose wheel steering is electrically controlled via the rudder pedals. Trim functions, microphone keying, autopilot override and steering system switches are located in the control wheels. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Emergency extension can be accomplished pneumatically in case of hydraulic or electrical system failure. Embraer is the latest manufacturer entering the business jet market with the Phenom and Legacy lines of business jets. 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. . 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. The passenger compartment has the bench seat and two individual chairs arranged in club configuration. On May 17, 2017, a Learjet 25B registration XA-VMC operated by the company Aerotransportes Huitzilin S. A. de C. V. crashed at 3:26p.m. local time shortly after taking off from Toluca International Airport, Mexico bound for Durango. I tend you use the Honeywell name for the engines.
