Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. 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. Discussion in 'Aviation Chat' started by vrsurgeon, Aug 3, 2012. I've never flown the Lears, but wouldn't an old 25 have a hard time with noise restrictions at most airports? Introduced September 23, 1980. The 51,000 feet altitude Certification was added for all 25D/F models, although the specs are a little vague in the XO manual. This GLJ-25 SE should easily cruise at FL510 at ~450 kts with half fuel and 4 passengers. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. In July, 2008 this same barrel of oil hit a new high of $147.27. I like this Classic Learjet a lot. This added a stall strip and full-chord wing fence to create an aerodynamic warning and a straight-ahead stall. This was caused by the weight of all that fuel in the tip tanks. It only takes about 5 minutes to jettison the necessary fuel from the tip tanks, but it is so enjoyable. hmm. ( 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 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. Search for the string learjet 24/25 MrMoo pdf. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. This method was first used by Lionheart Creations in their Lear 24B add on and makes great use of the limited panel space. 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. Most accounts state that 64 base model 35s were built before the Models 35A and 36A arrived with upgrades throughout but mostly increased fuel load and therefore increased endurance. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. You can only carry so much fuel and still have room for a few passengers. 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. 2023 GlobalAir.com. 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 Phenom 300 is marketed as direct competition of the smaller Bombardier Learjets and Citation CJ3/CJ4. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). Ouch. 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. Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). Moving the tip tanks out undoubtedly added inertia and so, to increase lateral control without heavying up the feel, spoilerons are now used for additional roll command. 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. Now, that is a really small diameter fuselage. The GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. These numbers were soon eclipsed by Cessna and their Citation line of business jets. Props and jets from the good old days, Flight Decks Is this a review on a flightsim website, or Wikipedia ? A side benefit was the thicker wing section adds 15 square feet of wing area and allows for 81 more gallons of fuel. At this speed, the Learjet 25 glides approximately 26 nautical miles for each 10000 feet of altitude loss. Single engine performance is good with the single engine rate of climb approximately 1700 feet per minute at gross weight at sea level and a single engine service ceiling of approximately 21500 feet. 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. The leading edge of the standard wing sweeps back at a 13-degree angle to a straight trailing edge. I was a dyed in the wool Cessna Citation fan for a long time and really still am, but you have to love the speed and power of these early Learjets. 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, [1], Data from Jane's All The World's Aircraft 197677[11], Learjet 25B/25C Pilot's Manual, Gates Learjet Corporation, Wichita, Kansas, 1971, Learn how and when to remove this template message, "For many models, market hitting the apex", Information page from Aviation Safety Network, "Aviation Safety Network Accident Description - 2 March 1996", "Plane of singer Jenni Rivera missing in Mexico. The Learjet 25 cabin is pressurized to enable high altitude operations without the use of supplemental oxygen. Now about that General Electric CJ610 turbojet engine. The Lear 60 is also still rolling down the line, and within weeks the "Continental" will roll out its first production aircraft. This creates room for a big-airplane-type refreshment cabinet on the left side of the cabin. The Mode Selection switches, Altitude Pre-selector, and AP Vertical Speed Selector are mounted helter-skelter, just as the real world classic Learjets. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 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. Accident, incident and crash related photos, Air to Air A 25 will burn more fuel, of course, but that's only part of the equation. Due to the ease of converting the cabin the Learjet 25 has found a niche as a medevac aircraft. Thanks for the info..that was a great help? A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. Ask the man who owns one Actually that bit of airport rumor comes via a PC-12 operator up here. 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 landing gear, brake, flap and spoiler systems are hydraulically operated. 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. ( A fully outfitted and animated cabin in included with 70s style airwork. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. Go get it here. 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. March 28, 1980 - Gates Learjet flies high with its one-thousandth sale. 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. They even had the engine model numbers and thrust level properly identified. 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. 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. Both pilots died. Oops. The Bombardier Learjet 60 can cruise at up to 51,000 feet. Passenger cabin shots showing seat arrangements as well as cargo aircraft interior, Cargo Aircraft The main gear has dual wheels and brakes on each strut. With this setup I can use standard weights of 170 lb men and 120 lb women and carry a small amount of baggage with full fuel and be slightly under Max Ramp Weight of 15,300. The fuel inefficiency, the limited range, and the airport noise problem. 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. The H-valve position can be adjusted by the crew to increase or reduce the amount of bleed air cooling at the heat exchanger. Check column 5, for the 1,000 nm comparison of the fuel burn. Microsofts planned layoffs will hurt MSFS or not? Click here for more information and to see all donations year to date. Trim functions, microphone keying, autopilot override and steering system switches are located in the control wheels. The oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. The tip tanks provide additional fuel capacity to enable longer times aloft. An integral anti-skid system in installed to affect maximum braking efficiency. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. 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. They are practically identical to the engines in the supersonic T-38A Air Force jet that the Thunderbirds flew for years, except the civilian version does not have the afterburner. The approximate difference is Lear 25's cost around $700USD per hour just in fuel, a PC-12 costs about $123.50. Both look like Learjets. Your burn rate is probably 140-175 gal/ hour, depending on power settings. Sorry, sometimes I get carried away with this stuff. 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 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. Everything from the Goodyear blimp to the Zeppelin, Night Photos This Century III wing did not alter the Learjets tendency to roll off sharply during a stall. As the wheel rotation speed accelerates to normal tolerance limits, normal braking pressure is restored. Long Range Cruise Speed 418 kts, Rate of climb 6,050 fpm, one engine ROC 1,910 fpm. WebThe 25 seats up to 10 passengers plus 2 pilot (s). When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. 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 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. The hydraulically retractable landing gear is of conventional tricycle configuration with air-hydraulic shock-type nose and main gear. 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. 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. Two disc-type indicators are flush mounted under the left engine. Has anyone heard of Learjet proposing to make a new lear? What is not shown in the accompanying artists sketch is just how large those new Garrett engines would be, or the fuselage stretch, or the increased wing span with that now familiar looking two foot section added out near the tips. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. The Venezuelan armed forces forced the Learjet to land on suspicion the aircraft was being used for "illicit activities," possibly involving drugs smuggling. That all makes a big difference as to practicality, purpose, and just plain thrill factor! 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. WebThe Learjet 25D is powered by General Electric CJ610-8A engines with 2,850 pounds of thrust. The time required to accelerate from idle to 100% RPM is approximately four seconds. 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. 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. Enough of the background and similar Learjets, let look at the Learjet 25D that inspired the Xtreme Prototypes design team. The Learjet 24 had several variants, designated by letters A, B, C, D, E, and F. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 All three installers are included. Most Learjet 25 aircraft were fitted with a fuselage tank. I wonder why they decided to start with a new version 2.0? ) Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. 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. But first, they needed to stop the bleeding and improve the cash flow at their newly acquired Learjet factory. If it floats or flies rent it. ( Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. Our large helicopter section. The indicator face is divided into green (safe), yellow (caution) and red (danger) segments. 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. 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. VRSURGEON also didn't state where his Family is, possibly not near a commercial field? At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Additionally, the Learjet 31 has an average hourly fuel burn of 177 Gallons per Hour (GPH). In 1974 the Peruvian Air Force purchased two 25Bs with a belly pod that contained an aerial survey camera. The rudder pedals mechanically operate the rudder for directional yaw control. By the Numbers Recent Learjet sales is a very weak third place behind Cessna and Embraer. 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. This puts the crew on a longer arm to help bring the cg within the envelope. Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. Hence, the reduced Max Landing Weight. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). The autopilot head unit is mounted on the lower center console immediately below the Fuel Control Panel. GlobalAir.com is your partner in connecting you with relevant information and resources. Wow. These were contributed by none other than Ryan Butterworth in his mini-review as it is being called and a few others fans of the Classic GLJ25. Tips and recommended settings for beginners are included but so the seasoned pilots that want to get up and flying quickly Alain has included a separate 2-page Quick Start. 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. 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. Our Model selected for this review is in the center. 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. How much does it cost to operate these aircraft? Emergency extension can be accomplished pneumatically in case of hydraulic or electrical system failure. On April 10, 2014, a privately owned Learjet 25D was destroyed on the ground by Venezuelan forces. I understand that a new French language edition of the manual is almost complete. Just use the Find function and locate the values in the aircraft.cfg file and make your changes. 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. The engine compartments consist of an eight-stage axial-flow compressor directly coupled to a two-stage turbine, a through-flow annular combustion system, variable inlet guide vanes, controlled compressor interstage bleed, exhaust nozzle and accessory drive system. The largest seller is the Model 25, but more 35s were sold in the past six years. 100 hours a year isn't worth owning an airplane. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. 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. The panel has been cleaned up, regrouped and made somewhat prettier. The Go Around feature is especially well done, be sure to learn more about it. High Speed Cruise 475 kts Or you could always get a Notar. The Lear loves to be at FL400. 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. 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. All the early or classic Learjets had to burn off about 2,000 pounds of fuel to get the weight down to the Maximum Landing Weight. The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. 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. http://www.ferrarichat.com/forum/showthread.php?t=370969, (You must log in or sign up to post here. A 25 will burn more fuel, of course, but that's only part of the equation. 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. A jet pump installed in each tip tank transfers fuel into the wing tanks. This is an FSX limitation, no Ramp Weight field. The Models 35/36 and all the winglet models have much larger engines cowlings and a slightly longer fuselage than the Model 25D. 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. 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. The brake valves are controlled via the rudder pedal toe brakes through mechanical linkages. Just so you know the details Timberland shoes, Flysimware Learjet 35, SPAD.next, Volair Avionics Panel, and the new Aerofly FS2 simulator. An oxygen rupture disc will relieve oxygen pressure if the oxygen cylinder pressure reaches 2700 to 3000 psi. This is not a problem in the real world cockpit but is a pain in most desktop simulator models. One click on the 8-Track tape player will start, move to the next selection, or stop the music. 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. It's got autopilots that will do everything but put sugar in your coffee. It's got autopilots that will do everything but put sugar in your coffee. The aircraft's high rate of climb enables it to pass congested flight levels quickly.
