I cant speak for the Legacy systems, but Ryan Butterworth says he has a something less than the best system and he has posted some Frame Rates compared to some of his other addons. Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. Time to Look at the Excellent Flight Manual. Lears made their mark with exceptional speed and high-level cruise. The passenger compartment has the bench seat and two individual chairs arranged in club configuration. 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. Conventional wing flaps are used to improve low speed flying characteristics and reduce landing and take-off speeds. 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. It is easy to see why the turbojet was on the top of the list for replacement with fuel prices skyrocketing. A rate controller enables the crew to select the rate pressurization of the cabin within preset limits. 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. 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 cabin temperature is controlled by regulating the temperature of the pressure bleed air that is routed through the cabin. The Learjet 25 also requires long runways at high altitude or ambient temperature. Quote: When I finally got the cabin worked out, I damn near shot myselfnot enough room. The pointer responds to the dynamic pressure from the pitot heads on the nose compartment. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. Hopefully Flysimware will tweak this accordingly. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft 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. Panel space is naturally very limited in a classic Learjet, but an improved and very nifty one-click rotating choice of three gauge clusters is available. Trim functions, microphone keying, autopilot override and steering system switches are located in the control wheels. Now, that is a really small diameter fuselage. 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 1,000 nm NBAA IFR mission can be flown in 2.1 hours, the 600 nm mission in 90 minutes. But, there's nothing like giving the " finger" to the commercial flying world! This has to do with the AP over rides of the pitch and roll and the VS modes. The largest seller is the Model 25, but more 35s were sold in the past six years. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. 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. 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. Selected information from the www.Xtremeprototypes.com website. 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. Gates Learjet delivered its one-thousandth airplane a Model 35A in late March to Eaton Corporaion of Cleveland, Ohio. 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. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. If you are looking for an up-to-date modern design, high definition, and highly detailed Classic Learjet, you cant do any better than this one. Has anyone heard of Learjet proposing to make a new lear? WebThe 25 seats up to 10 passengers plus 2 pilot (s). 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 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. 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. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. COPYRIGHT 1973, THE McGRAW-HILL COMPANIES, INC. ALL RIGHTS RESERVED. 2023 MOTORSPORT NETWORK. 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, Type development continued with the Models 25D and 25G, which included more advanced CJ610-8A engines and a ceiling increase to 51,000 feet. Tom Allensworth,
The bleed air is cooled in the heat exchanger by ram air entering the dorsal fin inlet and passing through the heat exchanger. What is missing in the Manual? 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. This one got interrupted a couple of times and I feel guilty that it took me so long to finally complete the review. 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. 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. All rights reserved. (But the cargo door is still available as an option.) Interested in buying this aircraft click here. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. Neither was long range endurance it was pure speed and the ability to get over the weather that moved corporate aviation to the jets. Two shuttle valves in the pressure lines prevent fluid feedback between the pilot's and copilot's pedals. 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. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). So, because the 35 and 36 are 2,000 pounds heavier than the 25, wing area had to be added to match the 25s performance. I especially like the fact that we get all three installers, 10 very nice repaints, an outstanding flight manual and a highly tuned flight model that will cruise at Mach 0.82. March 28, 1980 - Gates Learjet flies high with its one-thousandth sale. 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. Our large helicopter section. Jump straight to the total cost table of the Bombardier Learjet 31. Thanks for the info..that was a great help? Say on a 1 hour flight. 124.2 WebBombardier Learjet 25C M25C Civil 15,000 Fuel Burn (lbs) 980 1400 2150 2840 3630 5000 Bombardier Learjet 25D M25D Civil 15,000 Fuel Burn (lbs) 970 1410 2210 3020 3910 Bombardier Learjet 31 M31 Civil 15,500 Fuel Burn (lbs) 570 840 1330 1860 2380 3120 Near the back of the flight manual is a full page Limitations with all the V speeds and Placard speeds. Photo: Charlie Gates on left, Harry Combs on the right. Search for the string learjet 24/25 MrMoo pdf. 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. Sorry, sometimes I get carried away with this stuff. Installation extra. We all know the LearJet has gone through several iterations by 3 primary aircraft companies. Ouch. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. A fully outfitted and animated cabin in included with 70s style airwork. Actually Bill Lear himself summed it up nicely. 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. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. I was disappointed that the developer did not include any climb, descent, or cruise performance charts in the Flight Planning section. I use the following for my personal flying in the flight sims. The spoilers provide an effective means of increasing normal rates of descent and may be used as a drag device to achieve rapid airspeed deceleration. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. Your burn rate is probably 140-175 gal/ hour, depending on power settings. The Sun visors do more than flip up or down. There are more Learjets in service than any other business jet. In 1974 the Peruvian Air Force purchased two 25Bs with a belly pod that contained an aerial survey camera. These boundary layer energizers are small spanwise ridges on the upper wing surface just ahead of the aileron. I understand that a new French language edition of the manual is almost complete. The Learjet 25 generally has five fuel tanks. This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. Some of the animations only work either in the Lockheed Martin P3D edition or FSX, but, the performance and pleasure of flying a high performance classic Learjet with 3d gauges in an ultra HD virtual cockpit using our latest 3rd party avionics is outstanding. The 25 seats up to 10 passengers plus 2 pilot(s). The thrust reverser paddles are removable with a single click so we can see the partially hidden switches. 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. Check column 5, for the 1,000 nm comparison of the fuel burn. Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. ( Parts for the 25 series are becoming some what of a problem, as 35 series is a much better aircraft in regards to operating costs. The Gates team was concentrating on designs to replace these General Electric turbojet engines with the much more fuel efficient Honeywell turbofan engines and designing new supercritical wings with winglets rather than wingtip fuel tanks. 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. There was never a 25E model, but there was a 25F that was grouped in with the 25D production numbers. 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. Xtreme Prototypes hybrid model the Classic GLJ Model 25 Special Edition is based on one of the last true or original Lear Jet designs at the start of the Gates Learjet tenure. Accident, incident and crash related photos, Air to Air 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. Our GLJ 25SE flight model does indeed have the updated BLEs instead of the older vortex generators. 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. 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). 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. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. At this speed, the Learjet 25 glides approximately 26 nautical miles for each 10000 feet of altitude loss. 340 The 30 series have much more fuel efficient engines, not to mention quieter. VRSURGEON also didn't state where his Family is, possibly not near a commercial field? Best Range: 1875 NM They have their own book for the 30 series Learjets. You can use 15,300 pounds as ramp weight with a MTOW of 15,000 lbs. 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. Get my point? It's got autopilots that will do everything but put sugar in your coffee. 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. 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). Hence, the reduced Max Landing Weight. The leading edge of the standard wing sweeps back at a 13-degree angle to a straight trailing edge. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. The DC system is powered from two 28 Volt, 400 Amperes, engine-driven starter-generators. 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. 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. 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 Total Cost of Ownership: $700,646.69 Photos: Left, Lear 28 flown by Neil Armstrong setting climb records, Middle, Photo from newspaper article with Armstrong in left seat, Right, the exact same Lear 28, s/n 28-001, flown by Armstrong on February 19 and 20, 1979 for record setting events with modern paint job and new tail number. Monobromotrifluoromethane (CF3BR) is used as extinguishing agent. The Bombardier Learjet 45XR can cruise at up to 51,000 feet. Both look like Learjets. 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. The flaps are hydraulically operated. 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. 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. Only $1.1 MM for the full mod. 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. So, 10 percent of this essay, is "Review", and 90 percent about the history of the Learjet ? That is really nice. These numbers were soon eclipsed by Cessna and their Citation line of business jets. Twin engine turbojet aircraft. WebBombardier Learjet 25C M25C Civil 15,000 Fuel Burn (lbs) 980 1400 2150 2840 3630 5000 Bombardier Learjet 25D M25D Civil 15,000 Fuel Burn (lbs) 970 1410 2210 3020 3910 Bombardier Learjet 31 M31 Civil 15,500 Fuel Burn (lbs) 570 840 1330 1860 2380 3120 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. Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. Intersting. 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. 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. 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. 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. The Model 25D with the -8A mods was actually a better performing engine at very high altitudes than the Garett TFE731-2 fanjets designed for the Model 35. Just to whet your appetite, I have a few closeup screenshots to show some of the HD detail. This is really my only disappointment in the cockpit. The drag chute has been deployed in a crosswind of up to 20 knots under actual test conditions. Most charge anywhere from $1200 to $1800 and hour for these birds. 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.
