lear 25 fuel burn

The GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. One of my favorites is the show/hide throttles feature so I can see the light switches. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. . ( 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. This method was first used by Lionheart Creations in their Lear 24B add on and makes great use of the limited panel space. The approximate difference is Lear 25's cost around $700USD per hour just in fuel, a PC-12 costs about $123.50. Now, that is a really small diameter fuselage. Let's not even talk about the cost in maintenance on a 30 year old plane. 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. These two important reasons are near the top of the priority list, but the fact that most everyone was convinced that taming the noise levels of this military adapted gas guzzling high performance turbojet engine was going to be near impossible. The vanes provide regulated voltage input to the angle-of-attack transducers, modified by a stall warning bias box to compensate for flap position. 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. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. Selected information from the www.Xtremeprototypes.com website. FSX Boxed, Steam, P3D v2-3. 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. Has anyone heard of Learjet proposing to make a new lear? Approach reference speed was cut by 12 knots and the landing runway requirement was reduced by more than 800 feet. Good luck. Mr. Gates took over as President and COO of Lear Jet and Bill Lear stayed on for a year or so as Chairman but wasnt involved in the Lear Jet project or day to day operations. The Mode Selection switches, Altitude Pre-selector, and AP Vertical Speed Selector are mounted helter-skelter, just as the real world classic Learjets. 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. Practically everything is the cockpit is clickable, moveable, animated in some way and can be used to simulate an action or procedure. The thrust reverser paddles are removable with a single click so we can see the partially hidden switches. 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. This is a very handy feature. Views from inside the cockpit, Aircraft Cabins Flying Magazine, June 1980. 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. Ouch. It comes only as a pdf and in two editions the full blown 160 pages that in provided to registered user and a still excellent 70 page Sample Version for those who wish to see some detail prior to purchase. Because this new release is specifically designed for newer PC and video cards, you can expect superior performance. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. 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 It is fairly easy to narrow down the identity of a Learjet with 3 or more small fuselage windows with large wingtip fuel tanks. And, of course, the TFE 731 meets FAR 36 noise requirements and is a much cleaner running powerplant than the GE was. 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. A side benefit was the thicker wing section adds 15 square feet of wing area and allows for 81 more gallons of fuel. Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. COPYRIGHT 1973, THE McGRAW-HILL COMPANIES, INC. ALL RIGHTS RESERVED. WebThe Learjet 25 generally has five fuel tanks. 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 30 series have much more fuel efficient engines, not to mention quieter. To correct for the wing drop, in 1979 Gates introduced another improvement call Softflite. 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.

Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. Not to mention the ability to file a flight plan, and go on a moment's notice. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. The brake system incorporates four power-boosted disc-type brakes with integral anti-skid system. 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. FC-110 with Yaw Dampers. For some reason, this XP GLJ 25D SE has all the switches and lights but does not have the system coded. For practicing the return to the airport procedure, I start with 13,500 pounds Gross Weight so I can burn off 200 pounds of fuel on takeoff and return for a landing. Long Range Cruise Speed 418 kts, Rate of climb 6,050 fpm, one engine ROC 1,910 fpm. The Lear loves to be at FL400. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Installation extra. I did notice that the Sample Manual does not have the full Flight Planning section that is only available to those that purchase the add-on. This is not a problem in the real world cockpit but is a pain in most desktop simulator models. A used Lear @ $675,000USD will cost more than the savings on a PC-12 over the course of a year. 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 Each engine is rated at 2950 pounds of thrust at sea level. Many don't put that on their FCar in decades. The Learjet 25 is a challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. The control wheels operate the elevator and ailerons mechanically through a system of cables, pulleys, push-pull tubes and bell cranks. The lanyard is attached to the aircraft at the forward end of the tailcone access door opening. Our Model selected for this review is in the center. Here is a recent price break down from Business and Corporate Aviation magazine. Exactly which specific model is this Classic Learjet? This doesnt raise the cruise speed Mach limits but does provide a greater safety margin in turbulence or when maneuvering at high speeds. ) The 1,000 nm NBAA IFR mission can be flown in 2.1 hours, the 600 nm mission in 90 minutes. 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. The main gear has dual wheels and brakes on each strut. The largest seller is the Model 25, but more 35s were sold in the past six years. Most charge anywhere from $1200 to $1800 and hour for these birds. 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. As good and as detailed and as beautiful as this GLJ Model 25s flight manual may be there is still room for improvement. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. The engine pressure ratio (EPR) system enables the pilot to obtain power required to meet certified aircraft performance without exceeding engine limitations. 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. You will want to read the manual and maybe read the forums to become familiar with this early Automatic Flight Control System (AFCS). There are more Learjets in service than any other business jet. 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 Model 25G received a thicker wing section where the wing joins the fuselage. The Classic GLJ Model 25 SE runs smooth as butter on my test system. 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. 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. I am getting a little lazy in my old age so I am going to paste the GE engine history here in lieu of typing it from scratch. This was caused by the weight of all that fuel in the tip tanks. Some of the milestones credited to Gates leadership was actually accomplished prior to the Gates takeover. The Model 28 and 29 Lears were test beds for adding winglets and testing early version of the eventual Garrett AiResearch fanjet engines that were first used for the Model 35 and 55 Longhorn. That is really nice. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. Hopefully Flysimware will tweak this accordingly. ) This excellent throttle response enables rapid acceleration and precise power settings. (the Learjet 25D was certified for FL510).
