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. Each system has a detailed description along with a key to every switch, gauge, and instrument. 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. The airplane had reportedly departed Belm, Brazil without a flight plan and with the transponder turned off. Fair enough. A tank cross-flow valve is installed to prevent fuel transfer between wing tanks. - Features that would be useful to you. Phantom Aero Technical ATTC034, (1998), Johannesburg, This page was last edited on 17 January 2023, at 05:24.

Lears made their mark with exceptional speed and high-level cruise.

Tom Allensworth, See this picture and article found in the June 23, 1969 edition of Aviation Week and Space Technology magazine. ( This added a stall strip and full-chord wing fence to create an aerodynamic warning and a straight-ahead stall. 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. 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. Normal Cruise Speed 443 kts At 6000 feet elevation, 50 degrees Fahrenheit and with an average load of 5 passengers, the Learjet 25B will require approximately 8000 feet of runway. A 25 will burn more fuel, of course, but that's only part of the equation. There was never a 25E model, but there was a 25F that was grouped in with the 25D production numbers. That's a ton of Family! Other than a few improvements in avionics, tires, adding anti-skid brakes, and fuel dump valves in the tip tanks, and introducing single point refueling, most of the later model 20 series Learjets were simply trading passenger seats for larger fuel tanks or vice versa.

It took a year or more to realize they really needed an updated Model 35A and an extended range Model 36A. Just use the Find function and locate the values in the aircraft.cfg file and make your changes. To complete the design efforts that started with the somewhat simplified plan of upgrading the Model 25 with newer fuel efficient and quieter engines with a little more thrust turned into a longer, wider, more powerful new model with much improved low speed handling while retaining excellent cruise speeds at the highest flight levels allowed. Raisbeck Engineering has made a business of designing and marketing improvement to a large range of corporate aircraft. A safire is a four passenger jet (6 if you include the pilot seats) that sells for around $970,000 new. But, the standup and walk around Learjet cabin would arrive at a later date with the 40 and 60 series. 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. Ouch. Meanwhile, we now have an up-to-date, high performance, high definition, highly accurate representation of a classic early LearJet designed for our modern PC and video cards for both FSX and P3D. Two disc-type indicators are flush mounted under the left engine. These numbers were soon eclipsed by Cessna and their Citation line of business jets. The spoilers provide an effective means of increasing normal rates of descent and may be used as a drag device to achieve rapid airspeed deceleration. You need to be a member in order to leave a comment. The 1,000 nm NBAA IFR mission can be flown in 2.1 hours, the 600 nm mission in 90 minutes. If you are looking for an up-to-date modern design, high definition, and highly detailed Classic Learjet, you cant do any better than this one. 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. Leasedont buy. Two wing tanks, a fuselage tank and two wing tip tanks. The Mode Selection switches, Altitude Pre-selector, and AP Vertical Speed Selector are mounted helter-skelter, just as the real world classic Learjets. Evidently this was sound planning because at the end of production, the 30 series, small fuselage, Garrett powered models accounted to just shy of a thousand airplanes delivered to happy Learjet customers. 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. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. One of the Learjet milestones was the delivery of the 500th Learjet, Learjet 25D on April 8, 1975 to the Mexican Navy. Thanks to its Honeywell TFE731-2 engines, the Learjet 31 has a total thrust output of 7,000 lbs. Me, I would not touch a Lear 25 just because of age. What about a King Air 90 or Cessna 421? As good and as detailed and as beautiful as this GLJ Model 25s flight manual may be there is still room for improvement. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. Typical Price: $2,296,212.00 I read that you can expect to find 80 animations and in another paragraph I read that there were hundreds of cockpit animations so start looking and expect a few pleasant surprises.

Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. (the Learjet 25D was certified for FL510). No extra charges for P3D. Now about that General Electric CJ610 turbojet engine. 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 Normal Checklist and Procedures are far more than simple lists each item has a reference to a page number and a figure in the manual in addition to the action required. 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. WebEvery Lear that comes out of the factory is equipped to fly itself. Conventional wing flaps are used to improve low speed flying characteristics and reduce landing and take-off speeds. A pre-owned Lear 70/75 fetches between $5.50 million and $9.25 million. You can read those reviews here and here. The panel has been cleaned up, regrouped and made somewhat prettier. Beautiful shots taken while the sun is below the horizon, Accidents The Lear 45 is a "fresh sheet" Lear that is already in production. 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. Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. As an example, a tiny little 3" computer style box fan that goes into the headliner , for the interior environmental system on a Cessna Citation is worth about $4.00 at Radio Shack, but you are obligated to use the Cessna part, or one identical, that is certified, for well over $1,000.00 , just for the part.
