The Bombardier Learjet 60 can cruise at up to 51,000 feet. 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. 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. If enough folks who buys this add-on and also wishes it included the Fuel Jettison feature would simply ask that it be put on the list for any possible updates, changes, fixes, etc. Photo: Charlie Gates on left, Harry Combs on the right. Best Range: 1875 NM A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. However, it has been often at the cost of fuel efficiency. Or you could always get a Notar. 340 Beautiful shots taken while the sun is below the horizon, Accidents You can also add EICAS gauges from the Lear 45 FSX/P3D default model. The drag chute has been deployed in a crosswind of up to 20 knots under actual test conditions. My screen images are not as sharp as it should be but, I just cant seem to find to time to tweak it. 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. There were no plans to increase the length or height of the small tube fuselage so this Model 35 would not be in competition with the future 40 and 50 series enlarged fuselage models. Phantom Aero Technical ATTC034, (1998), Johannesburg, This page was last edited on 17 January 2023, at 05:24. In July, 2008 this same barrel of oil hit a new high of $147.27. If it floats or flies rent it. The inboard doors are hydraulically operated while the outboard doors are mechanically operated by linkage connected to the main gear struts. Two motor-driven shutoff valves will stop hydraulic flow to the engine-driven pumps in case of an emergency. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. Type development continued with the Models 25D and 25G, which included more advanced CJ610-8A engines and a ceiling increase to 51,000 feet. How much does it cost to operate these aircraft? Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. This has always been a choke point, restricting airflow and creating drag at high speed. This is from the XP Flight Manual. The time required to accelerate from idle to 100% RPM is approximately four seconds. The Learjet 25 generally has five fuel tanks. The Model 31A /ER was the long range version which added an additional 275 miles to the range. While writing this review, I got sidetracked with some new introductions to some of my older stuff that I had written reviews a couple of years ago. 124.2 The Learjet 25 is a challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. ( The hot section on a PC-12 is the same as one engine of a King Air 300, just a little more than one on a King Air 200. 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. Flying yourself's a beautiful thing! I use the following for my personal flying in the flight sims. The official price of a barrel of Saudi Light crude oil was $12.37 in the mid-1970s. Thanks for the info..that was a great help? 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. This mode is suitable for straight taxi, takeoff and gentle turns. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. Four additional shuttle valves connect the pneumatic system to the brake system for emergency braking. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. A safire is a four passenger jet (6 if you include the pilot seats) that sells for around $970,000 new. The thrust reverser paddles are removable with a single click so we can see the partially hidden switches. I tend you use the Honeywell name for the engines. Simply put, a shorter cabin to make room for more fuel. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. The oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. It is easy to see why the turbojet was on the top of the list for replacement with fuel prices skyrocketing. 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 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 40 is a 45 that has about 26 inches chopped out of the fuselagealso in production and certification with first flight scheduled for March. Hopefully Flysimware will tweak this accordingly. - Send us pictures of your plane. Before we get into the specifics of our Xtreme Prototypess simulated GLJ 25 SE model, I would like to tell you the story, very abbreviated of course, of the trials and tribulations of designing a replacement for the Model 25. The main gear is enclosed by two doors after retraction. Exceptions may be granted. The first Model 25 flew on August 12, 1966, and the first delivery was in November 1967.[1]. It is fairly easy to narrow down the identity of a Learjet with 3 or more small fuselage windows with large wingtip fuel tanks. This explains why the extensions are constant chord. So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. It took a year or more to realize they really needed an updated Model 35A and an extended range Model 36A. Lears made their mark with exceptional speed and high-level cruise. hehehehe. 60 somethin gallon tank, 300nm+ range, I've stayed airborne for over 3 hours on one tank. Accident, incident and crash related photos, Air to Air Ouch. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. 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. 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. 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. 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. The cabin pressure is provided by the conditioned air entering the cabin through the distribution ducts and controlled by modulating the amount of air exhausted from the cabin. - Aircraft specific reviews and articles. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Primary steering mode allows up to 45 degrees angle of turn and is suitable for slow speed aggressive steering maneuvers. Long Range Cruise Speed 418 kts, Rate of climb 6,050 fpm, one engine ROC 1,910 fpm. 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. The passenger compartment has the bench seat and two individual chairs arranged in club configuration. 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. 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. 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. The angle-of-attack transducer supplies a proportional voltage to the angle-of-attack of the aircraft. Microsofts planned layoffs will hurt MSFS or not? If there was to be a Model 26, it would have most likely been powered by Garrett fanjet engines. Due to the many buyouts, mergers and takeovers, Garrett engines may be referred using the original name Garrett AiResearch, or AlliedSignal, or Honeywell. Aircraft painted in beautiful and original liveries, Airport Overviews The pointer responds to the dynamic pressure from the pitot heads on the nose compartment. The landing gear, brake, flap and spoiler systems are hydraulically operated. High Speed Cruise 475 kts 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. Lears made their mark with exceptional speed and high-level cruise. This excellent throttle response enables rapid acceleration and precise power settings. 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. Garrett fanjet Engines for the Model 35 a real hodgepodge of parts. Learn about cockpit equipment upgrades that are FAA mandated. Due to the ease of converting the cabin the Learjet 25 has found a niche as a medevac aircraft. 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, 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 Bombardier Learjet 31 can cruise at up to 51,000 feet. An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 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 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. 1. L-188, this rumor comes from a PC-12 operator up here, namely me. 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 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. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. 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. 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. 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. Embraer is the latest manufacturer entering the business jet market with the Phenom and Legacy lines of business jets. What about a King Air 90 or Cessna 421? 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. 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. 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. 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. Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. This creates room for a big-airplane-type refreshment cabinet on the left side of the cabin. Pretty heady stuff, this Century III wing mod. 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. An integral anti-skid system in installed to affect maximum braking efficiency. You will find more and more nifty features designed into this add on as you spend more time flying. A rate controller enables the crew to select the rate pressurization of the cabin within preset limits. A 25 will burn more fuel, of course, but that's only part of the equation. Dial markings are based on percent of maximum allowable engine speed. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. The autopilot head unit is mounted on the lower center console immediately below the Fuel Control Panel. On aircraft 25-061 through 25-180 the engine driven hydraulic pumps supply fluid under pressure of 1500 psi to the system pressure is maintained at 1250 to 1500 psi by a pressure regulator. I get frustrated with the older autopilots but they usually do what they were designed to do. Nose wheel steering is electrically controlled via the rudder pedals. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. How about time to climb to 15,000 meters (just shy of 51,000 feet) in 12 minutes, 27 seconds? Here is a recent price break down from Business and Corporate Aviation magazine.

As strong as that 8 spar wing might be, when you put more than a ton of weight on the wingtips and then land a little hard with a 7 ton airplane moving at 120 knots or so, something is most likely going to break and when it does it is very flammable. FAA certified on September 4, 1970. Of course, the Model 25 was an improvement of the Model 24 that had replaced the original Model 23 the one that started it all. You really need to do your self a favor, and go to your local private airport, find a Company that does Lear maintenance. Any changes are a little more difficult until you fully understand the logic and procedure. The Model 25G received a thicker wing section where the wing joins the fuselage. 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. Intersting. Fuel Burn Data.
