Both stories are somewhat amazing to me. The 1,500th Learjet was delivered in June, 1986. 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. Any changes are a little more difficult until you fully understand the logic and procedure. Some of this research was done for the Lionheart LR24B review and the follow-on comparison of the Learjet 24B to the T-38. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. For these faults, I apologize. 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. An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 psi. The landing gear, brake, flap and spoiler systems are hydraulically operated. Interconnecting cables synchronize the flaps throughout their range of travel and a limit switch located on the left flap sector prevents over-travel. WebEvery Lear that comes out of the factory is equipped to fly itself. Here is a photo of a Model 25 test plane with a Garrett fanjet on the right and a standard GE CJ610-6 turbojet of the left side. by the manufacturer or FAA. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. 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 25G was introduced in late 1980 mainly to set or break some speed records for publicity. COPYRIGHT 1973, THE McGRAW-HILL COMPANIES, INC. ALL RIGHTS RESERVED. Both military and civil versions, Blimps / Airships The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. Tom Allensworth, This was done with a two-foot extension on each tip. ) 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. This combination makes the 35 and 36 much less costly to operate than a 25B or C and it will give them one of the best single engine angles of climb of any of the jets. Dial markings are based on percent of maximum allowable engine speed. Every conversation stressed the Learjets FAR 25, Transport Category certification, the very same certification level as a Boeing 747. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. It's got autopilots that will do everything but put sugar in your coffee. In 1970 the Learjet 25B was produced along with the Learjet 25C in the same year. Due to the many buyouts, mergers and takeovers, Garrett engines may be referred using the original name Garrett AiResearch, or AlliedSignal, or Honeywell. 124.2 Two motor-driven shutoff valves will stop hydraulic flow to the engine-driven pumps in case of an emergency. On April 10, 2014, a privately owned Learjet 25D was destroyed on the ground by Venezuelan forces. Small stall strips were place on the leading edge with a newly designed stall fence. Intersting. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. This method was first used by Lionheart Creations in their Lear 24B add on and makes great use of the limited panel space. A 25 will burn more fuel, of course, but that's only part of the equation. 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.

You can find that post in the screenshot forum. Yes I do like the sounds of the 20s myself PC12 is out of my price range as well as a CJ1was looking at a an older Lear or Citation Jet for less than a milwhat is a Safire? Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. Good luck. Best Range (i): 1,590 NM Fuel Burn: 256.0 GPH Stall Speed: 90 KIAS Rate of climb: 6,900 FPM Ceiling: 45,000 FT Takeoff distance: 3,393 FT Landing distance: 3,310 FT Weights Gross Weight: 12,499 LBS Empty Weight: 6,150 LBS Fuel capacity: 834 GAL Ownership Costs 1965 Total Cost of Ownership: Register For Free Total Fixed Cost 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. 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. 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. Let's not even talk about the cost in maintenance on a 30 year old plane. It only takes about 5 minutes to jettison the necessary fuel from the tip tanks, but it is so enjoyable. Neither was long range endurance it was pure speed and the ability to get over the weather that moved corporate aviation to the jets. Has anyone heard of Learjet proposing to make a new lear? A rate controller enables the crew to select the rate pressurization of the cabin within preset limits. 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. A bit of a misnomer, the Long Range should be taken with a grain of salt. For instance, Gates supposedly upgraded all the production models to FAR 25, Transport Category certification level aircraft, while in fact the Model 24/24A aircraft were certified as Part 25 aircraft 8 months prior to any Gates involvement and the Model 25 was already in the approval process. WebThe 25 seats up to 10 passengers plus 2 pilot (s). 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. A fully outfitted and animated cabin in included with 70s style airwork. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. Accident, incident and crash related photos, Air to Air I just need to find the time to find all those 80 animations in the cockpit. The Lear loves to be at FL400. 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. 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. The 30 series have much more fuel efficient engines, not to mention quieter. Just use the Find function and locate the values in the aircraft.cfg file and make your changes. Evidently this was sound planning because at the end of production, the 30 series, small fuselage, Garrett powered models accounted to just shy of a thousand airplanes delivered to happy Learjet customers. 1. Hence, the reduced Max Landing Weight. Get my point? You know, that old just a few more lines of code, thing.. At high cruise speeds, they delay the onset of turbulent flow over the ailerons more effectively than the vortex generators and create less drag. 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. Understand that age equals maintenance because things wear out. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. 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. The tip tanks provide additional fuel capacity to enable longer times aloft. I exchanged a few emails with the developer about the Empty Weight found in the aircraft.cfg file and therefore in the dropdown Fuel and Payload box. This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. 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. 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. Fuel flow is indicated via a fuel flow system. The often mentioned price of Jet fuel in 1975 across the nation was less than 30 cents/gallon, but would go absolutely insane a few years later. 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. Our Model selected for this review is in the center. 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. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. AC current is provided by two 1000 Volt-Amperes (VA) solid-state inverters. The Bombardier Learjet 60 can cruise at up to 51,000 feet. 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. The official price of a barrel of Saudi Light crude oil was $12.37 in the mid-1970s. The pitch would be to corporate American and the world that the new Learjet was a safe and efficient means of doing business. Type development continued with the Models 25D and 25G, which included more advanced CJ610-8A engines and a ceiling increase to 51,000 feet. Or possibly several hours away from a commercial field? Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. 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. 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 engineers have effectively picked up another foot of cabin room by switching to a narrower, people-sized cabin door in place of the old cargo-width entrance. Even with a 35 look for as new as you can afford. 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. - Send us pictures of your plane. This one breaks new ground in advancement and efficiency because it is an all new design specifically intended for new high end PCs using the most up-to-date version of FSX:SE and Lockheed Martins P3D v2-3. Improved version with greater fuel capacity. Two wing tanks, a fuselage tank and two wing tip tanks. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. OK. A 25 will burn more fuel, of course, but that's only part of the equation. WebThe Learjet 25 generally has five fuel tanks. The brake system incorporates four power-boosted disc-type brakes with integral anti-skid system. Typical Price: $2,296,212.00 Phantom Aero Technical ATTC034, (1998), Johannesburg, This page was last edited on 17 January 2023, at 05:24. Search for the string learjet 24/25 MrMoo pdf. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Oxygen is always available for the crew and can be made available to the passengers manually or automatically. Oops. 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. Review: Classic GLJ Model 25 Special Edition, The Janitor - An Interview with Tom Allensworth, Interview with Joshua Howard Re MS FLIGHT - March 2012, Interview with LMOC Re P3D - September 2012, The AVSIM Hack - First Published in May, 2009, The AVSIM Hack - The Full Story - Published April 2013. Pretty heady stuff, this Century III wing mod. Nose wheel steering is electronically controlled by the rudder pedals, utilizing the synchro principle. The main gear is enclosed by two doors after retraction. WebThe Learjet 25 generally has five fuel tanks. There are so many flying around on medical runs, express cargo services etcI often wonder how much profit they compaines make on each flightI heard they charge big bucks the 20 series learjets are cheap to aquire but the fuel bill is a different story. Mainly because the two models were designed and built alongside each other and practically all the improvements being designed for the newer, slightly larger and better selling Model 35/36 were also being applied to the Model 25 provided it was cost efficient. FAA certified on September 4, 1970. 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. The 30 series have much more fuel efficient engines, not to mention quieter. The bleed air is cooled in the heat exchanger by ram air entering the dorsal fin inlet and passing through the heat exchanger. If it floats or flies rent it. I get frustrated with the older autopilots but they usually do what they were designed to do. The chute offers an addition safety margin, since it can significantly reduce the stopping distance. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. I think the upper level VMO is actually 350 kts, provided it has the Century III wing. This is from the XP Flight Manual. 47 No extra charges for P3D. 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. 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. 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 brake valves are controlled via the rudder pedal toe brakes through mechanical linkages. 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. 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. 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. 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. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. Sign up for a new account in our community. MSFS beta update [1.30.12.0] - January 17, 2023. Some of the milestones credited to Gates leadership was actually accomplished prior to the Gates takeover. The Learjet 25 is similar to the Model 24 but is 1.27 m (4ft 2in) longer, allowing for three additional passengers. 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. No warranty of . Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. This GLJ 25D (rw) would have been required to have the standard Fuel Jettison pumps, switches, and lights working for any flight. The 40 is a 45 that has about 26 inches chopped out of the fuselagealso in production and certification with first flight scheduled for March. Installation extra. I even like the default EICAS panel feature because I am only one click away from having the GTNs or weather radar in the panel. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). I decided on an Empty Weight of 7,168 pounds and a total fuel capacity of 1,055 gallons. Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. FSX Boxed, Steam, P3D v2-3. Disclaimer: Information on this site may not be accurate or current and is not valid for flight planning or any other aircraft operations. It is fairly easy to narrow down the identity of a Learjet with 3 or more small fuselage windows with large wingtip fuel tanks. 2023 GlobalAir.com. WebThe 25 seats up to 10 passengers plus 2 pilot (s). The Learjet 25 is a challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. 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". This added a stall strip and full-chord wing fence to create an aerodynamic warning and a straight-ahead stall. Lear never used an A designator for any production Model 25, only on the Model 24. You can also add EICAS gauges from the Lear 45 FSX/P3D default model. Most charge anywhere from $1200 to $1800 and hour for these birds. . 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. To overcome the problem, they added 13 inches to the fuselage ahead of the wings leading edge. I use the following for my personal flying in the flight sims. The Venezuelan armed forces forced the Learjet to land on suspicion the aircraft was being used for "illicit activities," possibly involving drugs smuggling. 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 The future of corporate jet travel was going to require more seats, more efficient engines, and decent cabin headroom. This excellent throttle response enables rapid acceleration and precise power settings. Actually Bill Lear himself summed it up nicely. The 30 series have much more fuel efficient engines, not to mention quieter. WebFuel Burn: 257.4 GPH Stall Speed: 87 KIAS Rate of climb: 6,800 FPM Rate of climb (1 engine out): 2,050 FPM Ceiling: 51,000 FT Ceiling (1 engine out): 27,000 FT Takeoff distance: 3,393 FT Landing distance: 3,310 FT Weights Gross Weight: 13,500 LBS Empty Weight: 7,327 LBS Maximum Payload: 3,760 LBS Fuel capacity: 840 GAL Ownership The leading edge of the standard wing sweeps back at a 13-degree angle to a straight trailing edge. Even better would be a full-blown tutorial flight or example flight. 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. At this speed, the Learjet 25 glides approximately 26 nautical miles for each 10000 feet of altitude loss. One click on the 8-Track tape player will start, move to the next selection, or stop the music. Tail and Winglet closeups with beautiful airline logos. This is an FSX limitation, no Ramp Weight field. 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. The stall warning system utilizes a stall warning vane on each side of the nose. 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. Bob Berry, Lears engineering test pilot and director of product assurance, says the program calls for the airplanes to have the same performance and handling characteristics of the Model 25. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. 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. 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. Trim functions, microphone keying, autopilot override and steering system switches are located in the control wheels. Lears made their mark with exceptional speed and high-level cruise. The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). 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. This Model 35/36 would be the last Learjet with those large wingtip fuel tanks. Robertson, of STOL fame, also took a crack at adding small winglets on top of the wingtip fuel tanks to try to enhance the endurance of the Model 25 along with replacing the GE CJ610 engines with PW JT15D-5 engines to add STOL capability to the already hot Model 25. The normal pressure relief valve will open at 8.9 psi differential pressure and the safety outflow valve will open at 9.2 psi differential pressure which is the maximum allowable differential pressure. This free Sample Version has more information in it than most developers provide for competing products. Time to Look at the Excellent Flight Manual. Due to the ease of converting the cabin the Learjet 25 has found a niche as a medevac aircraft. It's easy! The fuel inefficiency, the limited range, and the airport noise problem. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. 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. The pulsating dc voltage is averaged and forwarded through the selector switch to the fuel flow indicator. The problem it creates for me is that I have so many similar Learjets that after a while many of the systems seem to run together and I start confusing one with another. You can read those reviews here and here. 340 I know, I know why dont the developers get away from the round dial old stuff and give us a Lear 60XR with a fully integrated ProLine 21 system? Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. Rest assured, the productionl ine is still rolling right along. One of my favorites is the show/hide throttles feature so I can see the light switches. They can walk you thru the service cost aspect of a Lear. As good and as detailed and as beautiful as this GLJ Model 25s flight manual may be there is still room for improvement.

Now about that General Electric CJ610 turbojet engine. Here is a recent price break down from Business and Corporate Aviation magazine. The average price of the Learjet 25D is not currently available. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. Some were very popular and others were just bad timing or too expensive to justify. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. 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.
