In 2013, the FAA modified 14 CFR part 91 rules to prohibit the operation of jets weighing 75,000 pounds or less that are not stage 3 noise compliant after December 31, 2015. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. The Learjet 25D was first built in the mid-1970s but is still flying today. I forced myself to cut it short and I left out a lot of my research material. Due to the many buyouts, mergers and takeovers, Garrett engines may be referred using the original name Garrett AiResearch, or AlliedSignal, or Honeywell. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. - Send us pictures of your plane. 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 One of the Learjet milestones was the delivery of the 500th Learjet, Learjet 25D on April 8, 1975 to the Mexican Navy. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 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. The Lear 45 is a "fresh sheet" Lear that is already in production. I tend you use the Honeywell name for the engines. Fuelburn: 149.0 GPH Quote: When I finally got the cabin worked out, I damn near shot myselfnot enough room. Learjet Model 35/36 677 total built (including 80 USAF C-21A), Learjet Model 60 323 + built (in production, Learjet Model 45 300 + built (in production), Learjet Model 40 90 + built (in production), Learjet Model 70/75 75 total built (in production). This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. 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. 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 was done with a two-foot extension on each tip. Founder of AVSIM Online. As the wheel rotation speed accelerates to normal tolerance limits, normal braking pressure is restored. If utilization is 100 hours per year, that's about 20 trips a year. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 There was never a 25E model, but there was a 25F that was grouped in with the 25D production numbers. This has to do with the AP over rides of the pitch and roll and the VS modes. The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve (H-valve). I have a fast PC with a 970 video card, I should have bought a 980, but didnt. 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. The lower console is now wider, not double wide, but somewhat wider. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. 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. Learn about cockpit equipment upgrades that are FAA mandated. 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. Jump straight to the total cost table of the Bombardier Learjet 31. This is a very handy feature. See cover of AW&ST, December 6, 1982. 1. If you own the previous 20 Series add on from XP, keep in mind that this version 2.0 Special Edition is not an update or upgrade - this is a totally and completely redesigned new version. Two wing tanks, a fuselage tank and two wing tip tanks. I like this Classic Learjet a lot. Emergency extension can be accomplished pneumatically in case of hydraulic or electrical system failure. Most Learjet 25 aircraft were fitted with a fuselage tank. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. OK. 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. A green overboard indicator on the outside surface of the dorsal fin will be ruptured or missing to indicate that the rupture disc is not intact. Thanks to Alain Rouleau at xtremePrototypes.com for answering all my questions and providing the evaluation software. 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 cant speak for the Legacy systems, but Ryan Butterworth says he has a something less than the best system and he has posted some Frame Rates compared to some of his other addons. 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. 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 aircraft's high rate of climb enables it to pass congested flight levels quickly. Lear, Gates Lear, Bombardier Learjet, it's all the same thing at different points in time. This is really my only disappointment in the cockpit. The best glide distance with engines windmilling is obtained with a clean airplane configuration and with a glide speed of 160 to 170 knots. An acoustical kit is being developed for those earlier airplanes and they will remain in production for a little while longer. The CJ610-6 engines fitted to the Learjet 25 have very low inertia and accelerate rapidly. In July, 2008 this same barrel of oil hit a new high of $147.27. As good and as detailed and as beautiful as this GLJ Model 25s flight manual may be there is still room for improvement. If the red disc is ruptured, either or both the containers have been discharged overboard as a result of an overheat condition causing excessive pressure within the containers. 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. The Gates Rubber Company purchased all of Bill Lears interest for about $28 million in early 1967. That all makes a big difference as to practicality, purpose, and just plain thrill factor! It would have been a wonderful addition if they had spent another day or so and added the climb, cruise, and descent details to the example. The pulsating dc voltage is averaged and forwarded through the selector switch to the fuel flow indicator. Gates did not make any significant changes to the Model 25D because it was near the end of the design cycle for the highly inefficient fuel-guzzling GE turbojet engines and the short wings with the huge tip-tanks to carry the necessary fuel. Photos: Left, Lear 28 flown by Neil Armstrong setting climb records, Middle, Photo from newspaper article with Armstrong in left seat, Right, the exact same Lear 28, s/n 28-001, flown by Armstrong on February 19 and 20, 1979 for record setting events with modern paint job and new tail number. 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. 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. Things seem to be just fine at the Lear jet factory. Accident, incident and crash related photos, Air to Air 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? I took it one step further for my personal flying and in effect made an XR version for a little Extra Range. The official price of a barrel of Saudi Light crude oil was $12.37 in the mid-1970s. They even had the engine model numbers and thrust level properly identified. 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. The ICAO designator as used in flight plans for all Learjet 25 models is LJ25. The nose gear doors operate mechanically with linkages attached to the nose gear shock strut. Some of this research was done for the Lionheart LR24B review and the follow-on comparison of the Learjet 24B to the T-38. The PW JT15D-5 powers the Hawker 400XP with 3,400 lbst. Flying Magazine, June 1980. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. Oxygen is contained in a pressurized bottle located in the dorsal fin of the aircraft. 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 So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Part of MOTORSPORT NETWORK. By the Numbers Recent Learjet sales is a very weak third place behind Cessna and Embraer. 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. The cabin interior can be converted to several different configurations to allow for cargo and medevacs. Approach reference speed was cut by 12 knots and the landing runway requirement was reduced by more than 800 feet. Hopefully Flysimware will tweak this accordingly. The future of corporate jet travel was going to require more seats, more efficient engines, and decent cabin headroom. Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. Let's not even talk about the cost in maintenance on a 30 year old plane. The rudder pedals mechanically operate the rudder for directional yaw control. It is not perfect but any glitches or limitations are prominently discussed in the 160 page Flying Manual with suggestions for workarounds and hints on how to avoid any limitations of the simulators. Or you could always get a Notar. In cruise flight the Learjet flies at about a three-degrees nose-up angle so the engineers lowered the nose of the tip tanks three degrees.

WebThe Learjet 25 generally has five fuel tanks. The engine pressure ratio (EPR) system enables the pilot to obtain power required to meet certified aircraft performance without exceeding engine limitations. 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 am in the business.been flipping large commercial jets to airlines for 15 years. 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. Phantom Aero Technical ATTC034, (1998), Johannesburg, This page was last edited on 17 January 2023, at 05:24. Sign up for a new account in our community. The Bombardier Learjet 31 can cruise at up to 51,000 feet. This frequency is compared to a normal deceleration curve and if it deviates it activates a small torque motor in the affected wheel control valve which shunts braking pressure to the return line by means of a spool valve. Pilot workload is high and approach, landing and takeoff speeds are above average for civilian aircraft. 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. I have been told that to do a hot section on the engine in a PC-12 costs about the same as getting both sides of a King Air done. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes Jump straight to the total cost table of the Bombardier Learjet 31. Good luck. Every conversation stressed the Learjets FAR 25, Transport Category certification, the very same certification level as a Boeing 747. The 30 series have much more fuel efficient engines, not to mention quieter. The refrigeration system consists of a compressor, receiver dehydrator and evaporative cooler located above the baggage compartment. The GE CJ610-8A engines came directly from the military inventory. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. The Model 28 had the same fuselage and engines at the Model 25D but, totally different high aspect ratio wings, larger wing surface area and the first winglets for a production business jet. The hydraulically retractable landing gear is of conventional tricycle configuration with air-hydraulic shock-type nose and main gear. Photos: Original Model 23 (at Smithsonian) on left, yet to be built Model 85 on right. It had the old Air Force engines on it. The lanyard is attached to the aircraft at the forward end of the tailcone access door opening. The indicator face is divided into green (safe), yellow (caution) and red (danger) segments. 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. Two shuttle valves in the pressure lines prevent fluid feedback between the pilot's and copilot's pedals. Best Cruise: 417 KIAS 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. Is this a review on a flightsim website, or Wikipedia ? When the tank is full, a float switch de-energizes the wing boost pumps and closes the valve. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Alain Rouleau at Xtreme Prototypes is known for his excellent flight manuals and this one ranks right up there at the top of this list. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. By 2018, 1970s Learjet 25s were sold for under $200,000. A 25 will burn more fuel, of course, but that's only part of the equation. The average price of the Learjet 25D is not currently available. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. Long Range Cruise Speed 418 kts, Rate of climb 6,050 fpm, one engine ROC 1,910 fpm. I was at the Lear factory in Wichita about a month ago. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. The DC system is powered from two 28 Volt, 400 Amperes, engine-driven starter-generators. A side benefit was the thicker wing section adds 15 square feet of wing area and allows for 81 more gallons of fuel. 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? This Century III wing did not alter the Learjets tendency to roll off sharply during a stall. - Aircraft data that you believe is inaccurate or have specific experiences. 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. 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 offers an ideal high speed platform for business travel for six to eight passengers. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). 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.

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. we might get it one day down the road. Not much, but . 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. Just about any gauge can be added to this area with a little adjustment to the height and width of the gauge to fit the area available. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. 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.
