100 hours a year isn't worth owning an airplane. 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. Quote: When I finally got the cabin worked out, I damn near shot myselfnot enough room. Starting ignition is provided by a dual output capacitor-discharge system. 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.

An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 psi. So, 10 percent of this essay, is "Review", and 90 percent about the history of the Learjet ? The 30 series have much more fuel efficient engines, not to mention quieter. Oops. The engine pressure ratio (EPR) system enables the pilot to obtain power required to meet certified aircraft performance without exceeding engine limitations. The Lear loves to be at FL400. 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. 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. Your burn rate is probably 140-175 gal/ hour, depending on power settings. 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. The control wheels operate the elevator and ailerons mechanically through a system of cables, pulleys, push-pull tubes and bell cranks. 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. Hydraulic pressure for retraction and extension of the gear is transmitted by a system of tubing, hoses and actuating cylinders and is electrically controlled by limit switches and solenoid valves. Wow. The time required to accelerate from idle to 100% RPM is approximately four seconds. This is achieved by removing the starboard seating to allow for a stretcher, mounting oxygen bottles and intravenous drip equipment. 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. The Lear 45 is a "fresh sheet" Lear that is already in production. FSX Boxed, Steam, P3D v2-3. Time to Look at the Excellent Flight Manual. 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. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 Hence, the reduced Max Landing Weight. The landing gear, brake, flap and spoiler systems are hydraulically operated. 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. It is simple enough to modify the fuel capacity for a fuel tank and it is easy enough to modify the Empty Weight of the aircraft. The PW JT15D-5 powers the Hawker 400XP with 3,400 lbst. Lears made their mark with exceptional speed and high-level cruise. Normal Cruise Speed 443 kts Two wing tanks, a fuselage tank and two wing tip tanks. Credit: FROM THE OCTOBER 1973 BUSINESS & COMMERCIAL AVIATION. Not only is this feature available, it is super simple to accomplish and even easier to switch to alternate avionics such as the large EICAS panel from the default Lear45 or most any other payware gauge that will physically fit in the designated area. Trim functions, microphone keying, autopilot override and steering system switches are located in the control wheels. It is easy to see why the turbojet was on the top of the list for replacement with fuel prices skyrocketing. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. This method was first used by Lionheart Creations in their Lear 24B add on and makes great use of the limited panel space. The refrigeration system consists of a compressor, receiver dehydrator and evaporative cooler located above the baggage compartment. 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 The Sun visors do more than flip up or down. 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. The 30 series have much more fuel efficient engines, not to mention quieter. The 1,000 nm NBAA IFR mission can be flown in 2.1 hours, the 600 nm mission in 90 minutes. . The main gear has dual wheels and brakes on each strut. They can walk you thru the service cost aspect of a Lear. 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 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). 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. The passenger compartment has the bench seat and two individual chairs arranged in club configuration. Improved version with greater fuel capacity. Only $1.1 MM for the full mod. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). How much does it cost to operate these aircraft? The Bombardier Learjet 45XR can cruise at up to 51,000 feet. 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. I forced myself to cut it short and I left out a lot of my research material. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. This doesnt raise the cruise speed Mach limits but does provide a greater safety margin in turbulence or when maneuvering at high speeds. The 1,500th Learjet was delivered in June, 1986. Hopefully Flysimware will tweak this accordingly. 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. 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. Flying Magazine, June 1980. 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. They have their own book for the 30 series Learjets. 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. 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. This creates room for a big-airplane-type refreshment cabinet on the left side of the cabin. A drag chute is fitted as optional equipment on some Learjet 25 aircraft. I also changed the MTOW to read 15,300 (Max Ramp Wt) knowing I will be at the official 15,000 MTOW with a few minutes of taxi time. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. The Gates Rubber Company purchased all of Bill Lears interest for about $28 million in early 1967. 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. But, there's nothing like giving the " finger" to the commercial flying world! Engine bleed air is admitted through a flow control valve to a heat exchanger. All rights reserved.

Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. After a honest introduction to the turbine world, will you feel that playing with Ferrari's are chump change, by comparison. Now, it is loaded, maybe overloaded, with takeoff and landing calculation charts, tables and data. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Be careful though, and make sure you have a backup of your aircraft.cfg file and if you screw it up dont email the developer and ask for help. Discussion in 'Aviation Chat' started by vrsurgeon, Aug 3, 2012. The airplane had reportedly departed Belm, Brazil without a flight plan and with the transponder turned off. 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. Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. A rate controller enables the crew to select the rate pressurization of the cabin within preset limits. In order to minimize heat build-up in the brakes and reduce brake wear, pilots are advised to deploy the spoilers upon touchdown. I have a fast PC with a 970 video card, I should have bought a 980, but didnt. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. Leasedont buy. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. Tom Allensworth, No warranty of Get my point? Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). The Bombardier Learjet 60 can cruise at up to 51,000 feet. Fuelburn: 149.0 GPH 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. How about time to climb to 15,000 meters (just shy of 51,000 feet) in 12 minutes, 27 seconds? It is fairly easy to narrow down the identity of a Learjet with 3 or more small fuselage windows with large wingtip fuel tanks. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. In July, 2008 this same barrel of oil hit a new high of $147.27. A 25 will burn more fuel, of course, but that's only part of the equation. 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. 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. Every conversation stressed the Learjets FAR 25, Transport Category certification, the very same certification level as a Boeing 747. WebEvery Lear that comes out of the factory is equipped to fly itself. It's got autopilots that will do everything but put sugar in your coffee. There is no doubt that I totally overlooked several items that probably required months to research and code and I didnt even notice or failed to suitable take notice. Things seem to be just fine at the Lear jet factory. However, it has been often at the cost of fuel efficiency. Nose wheel steering is electronically controlled by the rudder pedals, utilizing the synchro principle. The Learjet 25D was first built in the mid-1970s but is still flying today. Coupled approaches work very well and the integration of the GPS and GTNs is excellent. The hydraulically retractable landing gear is of conventional tricycle configuration with air-hydraulic shock-type nose and main gear. 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. As the ignition cycle is completed, the igniter plugs cease sparking and combustion becomes self-sustaining. When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. Many consider the Model 31A the best of the 30 series and even the best flying Learjet of all small fuselage models. The Learjet 25 is a challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. Selected information from the www.Xtremeprototypes.com website. As those folks that built or bought homes near the new airports and then discovered just how loud these little Pocket Rocket Learjets could be as their dishes rattled and windows vibrated they pressed for more and more stringent noise controls. 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. The Learjet 25 utilize wheel brakes as the primary method for reducing speed after landing. Both military and civil versions, Blimps / Airships A side benefit was the thicker wing section adds 15 square feet of wing area and allows for 81 more gallons of fuel. This is really my only disappointment in the cockpit. 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. Lear never used an A designator for any production Model 25, only on the Model 24. This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. With literally a thousand gallons of jet fuel, you will not be able to fly 2,000 nm at anything other than at a reduced economy cruise setting. WebThe 25 seats up to 10 passengers plus 2 pilot (s). Just so you know the details Timberland shoes, Flysimware Learjet 35, SPAD.next, Volair Avionics Panel, and the new Aerofly FS2 simulator. 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 Classic GLJ Model 25 SE runs smooth as butter on my test system. 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. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. 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. A 25 will burn more fuel, of course, but that's only part of the equation. It took a year or more to realize they really needed an updated Model 35A and an extended range Model 36A. As an example, a tiny little 3" computer style box fan that goes into the headliner , for the interior environmental system on a Cessna Citation is worth about $4.00 at Radio Shack, but you are obligated to use the Cessna part, or one identical, that is certified, for well over $1,000.00 , just for the part. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. (the Learjet 25D was certified for FL510). The Model 25 was introduced just prior to Gates taking over the majority ownership of Lear Jet in late 1966. 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. 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. The Model 31A /ER was the long range version which added an additional 275 miles to the range. Jump straight to the total cost table of the Bombardier Learjet 31. There were only a handful of 20 series models after the 25D. The Model 35/36 would go on to sell an astounding 738 units. Intersting. hehehehe. 60 somethin gallon tank, 300nm+ range, I've stayed airborne for over 3 hours on one tank. Even more interesting might be why the Model 35 and 36 have that funny shaped 2-foot wing extension and why the plane is a foot or so longer than planned. 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. We all know the LearJet has gone through several iterations by 3 primary aircraft companies. But, the standup and walk around Learjet cabin would arrive at a later date with the 40 and 60 series. 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. Interconnecting cables synchronize the flaps throughout their range of travel and a limit switch located on the left flap sector prevents over-travel. Everything from the Goodyear blimp to the Zeppelin, Night Photos 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. Sure, there were some additional company names involved, but we can narrow it down to Bill Lears Lear Jet, Charlie Gates Learjet, and Bombardiers Learjet designs. 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. 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. All rights reserved. In 1974 the Peruvian Air Force purchased two 25Bs with a belly pod that contained an aerial survey camera. Now about that General Electric CJ610 turbojet engine. The original tips were aligned with the longitudinal axis. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. The day to day operations went to Harry Combs for several years as Gates gained momentum and established their sales strategy to promote the new Gates Learjet. The Softflite wing has boundary layer energizers in place of the vortex generators that were mounted ahead of the ailerons on the original Learjet wing. This puts the crew on a longer arm to help bring the cg within the envelope. The leading edge now sweeps back to the extensions, then breaks forward and parallels the trailing edge.

(But the cargo door is still available as an option.) Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft Dial markings are based on percent of maximum allowable engine speed. Logically laid out, with tons of high resolution, close up screenshots with lots of bullets, detailed descriptions of every bit and piece of the aircraft, charts, tables, checklists, procedures, illustrations, references, known issues, and so much more. Total Cost of Ownership: $700,646.69 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 now have these items properly introduced and scheduled in my new more leisurely work schedule. Monobromotrifluoromethane (CF3BR) is used as extinguishing agent.
