A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. Hopefully Flysimware will tweak this accordingly. The Bombardier Learjet 60 can cruise at up to 51,000 feet. 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. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. 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. 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. 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. A pressure switch will energize the pump if hydraulic pressure falls below a preset level and de-energize the pump when pressure returns to normal. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. 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. . 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. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. The leading edge now sweeps back to the extensions, then breaks forward and parallels the trailing edge. One big problem it would not solve is the headroom and elbow room. The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. 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. I doubt not a single person could tell the difference when flying this add-on in any of the 3 sims, but it makes for more realistic loadings when I use real world flight planning data. The Bombardier Learjet 60 can cruise at up to 51,000 feet. The average price of the Learjet 25D is not currently available. ) 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. 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. Best Range: 1875 NM Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). The big news is that the decreased fuel consumption increases the range of the airplanes about 40 percent. This is achieved by removing the starboard seating to allow for a stretcher, mounting oxygen bottles and intravenous drip equipment. 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". How much does it cost to operate these aircraft? One of the Learjet milestones was the delivery of the 500th Learjet, Learjet 25D on April 8, 1975 to the Mexican Navy. 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. It is easy to see why the turbojet was on the top of the list for replacement with fuel prices skyrocketing. Not only the F1 GTN but you can also have your working REX/Milviz Advantage weather radar. Get my point? Nose wheel steering is electrically controlled via the rudder pedals. The good news is that you can download some excellent training manuals that have color illustrations, full systems descriptions and the necessary performance charts specifically for the Model 24/25 Learjet not all of them but the full pack for Mach 0.77). 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. Our large helicopter section. The aircraft is equipped with AC (Alternating Current) and DC (Direct Current) electrical systems. 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 Single engine performance is good with the single engine rate of climb approximately 1700 feet per minute at gross weight at sea level and a single engine service ceiling of approximately 21500 feet. Primary flight control is achieved by use of dual control wheels and rudder pedals. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. Here is a recent price break down from Business and Corporate Aviation magazine. 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. The Model 25G received a thicker wing section where the wing joins the fuselage. I have been told that the aircraft likes the dutch roll during landing approach or the student like to do it and you need to declare fuel critical while taxing out. 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. Even with a 35 look for as new as you can afford. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. 124.2 Jump straight to the total cost table of the Bombardier Learjet 31. autopilot. The main gear has dual wheels and brakes on each strut. I decided on an Empty Weight of 7,168 pounds and a total fuel capacity of 1,055 gallons. Some aircraft have a 1000 VA auxiliary inverter that is used as an option for added system capacity. I have been told that the aircraft likes the dutch roll during landing approach or the student like to do it and you need to declare fuel critical while taxing out. All rights reserved. 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. The XP design team did a good job with what they had to work with. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. 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. 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. 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. Starting ignition is provided by a dual output capacitor-discharge system. It is fairly easy to narrow down the identity of a Learjet with 3 or more small fuselage windows with large wingtip fuel tanks. The autopilot head unit is mounted on the lower center console immediately below the Fuel Control Panel. The first Model 25 flew on August 12, 1966, and the first delivery was in November 1967.[1]. The lower console is now wider, not double wide, but somewhat wider. Fuel can also flow via the flapper check valves into the wing tanks, but the lower half of the fuel in the tip tanks must be transferred with the jet pump. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. At this speed, the Learjet 25 glides approximately 26 nautical miles for each 10000 feet of altitude loss. The crew seats now have three inches more fore and aft travel. Make sure you checkout the Approach plates and the iPad on the side panels. Lears made their mark with exceptional speed and high-level cruise. If utilization is 100 hours per year, that's about 20 trips a year. 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 July, 2008 this same barrel of oil hit a new high of $147.27. The 25 seats up to 10 passengers plus 2 pilot(s). Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. The Lear loves to be at FL400. I use the following for my personal flying in the flight sims. 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. The Learjet 25 is similar to the Model 24 but is 1.27 m (4ft 2in) longer, allowing for three additional passengers. Long Range Cruise Speed 418 kts, Rate of climb 6,050 fpm, one engine ROC 1,910 fpm. - Send us pictures of your plane. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. One click on the 8-Track tape player will start, move to the next selection, or stop the music. 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. Sign up for a new account in our community. The Learjet 25 is a challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. The Lear 45 is a "fresh sheet" Lear that is already in production. 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. I have been told that the aircraft likes the dutch roll during landing approach or the student like to do it and you need to declare fuel critical while taxing out. 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.
