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. Finally, the Xtreme Prototypes Classic GLJ Model 25 SE. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. The closer you zoom in to the panel to more you appreciate just how well these new 3D gauges are performing super sharp image for my old eyes. The low pressure compressor was taken from Garretts 660-series APU used on the 747, the high-pressure impeller is scaled from one used in the TPE 331 and T76 engines, and the turbine components are from the APU used in DC-10s. The crew seats now have three inches more fore and aft travel. 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 oxygen storage cylinder has a capacity of 38 cubic feet and is stored at 1800 psi. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. There were only a handful of 20 series models after the 25D. This would solve all three disadvantages of the Model 25 Learjet. This has to do with the AP over rides of the pitch and roll and the VS modes. Garrett fanjet Engines for the Model 35 a real hodgepodge of parts. Everything from the Goodyear blimp to the Zeppelin, Night Photos 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. 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. Bottom Line: A most definite Buy Rating. The aircraft is equipped with AC (Alternating Current) and DC (Direct Current) electrical systems. The Lear loves to be at FL400. ) 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. Just to whet your appetite, I have a few closeup screenshots to show some of the HD detail. When the aircraft speed is 7% above stall, the stall warning energizes a control column shaker that produces a low-frequency buffet signal through the control column to warn the crew. I forced myself to cut it short and I left out a lot of my research material. 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. 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". Oops. 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. Plus, the first jets, straight jets, ate fuel like it was going out of style, and they had quite a restricted range, This is not exactly what Bill Lear was telling his potential customers at the time, but was obvious to the new Gates team that had to pick up the pieces and move forward. Monobromotrifluoromethane (CF3BR) is used as extinguishing agent. As the wheel rotation speed accelerates to normal tolerance limits, normal braking pressure is restored. The cabin temperature is controlled by regulating the temperature of the pressure bleed air that is routed through the cabin. we might get it one day down the road. Some aircraft have a 1000 VA auxiliary inverter that is used as an option for added system capacity. 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. The inverter outputs are frequency synchronized through a paralleling bus tie. Typical Price: $2,296,212.00 Dial markings are based on percent of maximum allowable engine speed. Because this new release is specifically designed for newer PC and video cards, you can expect superior performance. Things seem to be just fine at the Lear jet factory. Talking about those small fuselage Learjets, take a look at this comparison of a Lear Model 25 fuselage diameter compared to the Learstar 600 design. 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. FAA certified on September 4, 1970. This is a very handy feature. You need to be a member in order to leave a comment. Photo: A Gates Learjet showing enormous size of fanjet engines. The Lear 60 is also still rolling down the line, and within weeks the "Continental" will roll out its first production aircraft. The panel has been cleaned up, regrouped and made somewhat prettier. 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. Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. Your burn rate is probably 140-175 gal/ hour, depending on power settings. autopilot. The leading edge of the standard wing sweeps back at a 13-degree angle to a straight trailing edge. 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. Flight planning or any other aircraft operations should only be done using official technical information provided 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. Nose wheel steering is electrically controlled via the rudder pedals. But they consume 40 percent less fuel at takeoff thrust and 24 percent less at cruise. Additionally, the Learjet 45XR has an average hourly fuel burn of 204 Gallons per Hour (GPH). The PW JT15D-5 powers the Hawker 400XP with 3,400 lbst. It is tough to click on a button with a mouse or press and hold a switch for temporary changes in the flight path while also keeping a hand on a joy stick or simulator yoke. Any Learjet 25s that have not been modified by installing noise compliant engines or "hushkits" will not be permitted to fly in the contiguous 48 states after December 31, 2015. The Lear loves to be at FL400. All rights reserved. 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. 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. Ouch. 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. 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. Neither was long range endurance it was pure speed and the ability to get over the weather that moved corporate aviation to the jets. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. 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. The original tips were aligned with the longitudinal axis. The Model 36A is identical to the 35A with the exception of the larger fuselage fuel tank and the necessary reduction in fuselage seats and baggage area to make room for the extra fuel. I am in the business.been flipping large commercial jets to airlines for 15 years. The use of oxygen is only required for emergency in case of depressurization of the cabin or contamination of the cabin air. 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.

I like this Classic Learjet a lot. Sorry, sometimes I get carried away with this stuff. A bit of a misnomer, the Long Range should be taken with a grain of salt. What about a King Air 90 or Cessna 421? This puts the crew on a longer arm to help bring the cg within the envelope. 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, At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour.

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. This created a little unexpected legroom in the cabin, and they even gave the crew a few more inches. Its amusing to speculate on the problems this much have given the engineers. Ouch. This is from the XP Flight Manual. But, there's nothing like giving the " finger" to the commercial flying world! The XP design team did a good job with what they had to work with. I get frustrated with the older autopilots but they usually do what they were designed to do. Starting ignition is provided by a dual output capacitor-discharge system. 124.2 Each system has a detailed description along with a key to every switch, gauge, and instrument. I understand that a new French language edition of the manual is almost complete. Or possibly several hours away from a commercial field? When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. 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. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. No warranty of A fully outfitted and animated cabin in included with 70s style airwork. Thanks for the info..that was a great help? Our large helicopter section. 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. In order to minimize heat build-up in the brakes and reduce brake wear, pilots are advised to deploy the spoilers upon touchdown. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. WebEvery Lear that comes out of the factory is equipped to fly itself. 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. A refrigeration-type cooling system is used for cooling and dehumidification while the aircraft is on the ground or operating at altitudes below 18 000 feet. Two wing tanks, a fuselage tank and two wing tip tanks. The GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. Wow. 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 stories are somewhat amazing to me. This creates room for one or dual INS control heads, which are necessary in these Lears since either of them has the range to pop over to Europe and on down into Africa or the Orient. 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 In addition to the speed efficiency the 25G gained 370 nm in range compared to the normal 25D.
