One of the Learjet milestones was the delivery of the 500th Learjet, Learjet 25D on April 8, 1975 to the Mexican Navy. The aircraft description and specifications section, instrument panels, systems description have their one chapter or section along with a an excellent flight planning chapter. Many consider the Model 31A the best of the 30 series and even the best flying Learjet of all small fuselage models. Production of the Learjet 24 began in 1966 and continued through 1977, with a total of 259 aircraft built. 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. WebEvery Lear that comes out of the factory is equipped to fly itself. Fuelburn: 149.0 GPH Your burn rate is probably 140-175 gal/ hour, depending on power settings. The Bombardier Learjet 45XR can cruise at up to 51,000 feet. See this picture and article found in the June 23, 1969 edition of Aviation Week and Space Technology magazine. The first modification to the original Learjet wing came in 1970 when the tip tanks were realigned. Ouch. This one got interrupted a couple of times and I feel guilty that it took me so long to finally complete the review. It is fairly easy to narrow down the identity of a Learjet with 3 or more small fuselage windows with large wingtip fuel tanks. Tail and Winglet closeups with beautiful airline logos. Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH). Logically laid out, with tons of high resolution, close up screenshots with lots of bullets, detailed descriptions of every bit and piece of the aircraft, charts, tables, checklists, procedures, illustrations, references, known issues, and so much more. Overall, this is one of the most detailed and complete add ons that I have in my virtual hangar. How much does it cost to operate these aircraft? Our large helicopter section. There were only a handful of 20 series models after the 25D. This is a very handy feature. This is an FSX limitation, no Ramp Weight field. The lanyard is attached to the aircraft at the forward end of the tailcone access door opening. 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. Thanks to Alain Rouleau at xtremePrototypes.com for answering all my questions and providing the evaluation software. One of our Planephd Experts will be in touch with you shortly. The pointer responds to the dynamic pressure from the pitot heads on the nose compartment. In terms of cost, the Learjet 45XR has an estimated hourly charter price of $4,000. We thank you for your support and hope you'll join the largest aviation community on the web. The add-on AP looks identical to the rea world version and probably works the same with the exception of those features that are not coded Roll Turn Knob and Pitch Command Wheel. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes The Mode Selection switches, Altitude Pre-selector, and AP Vertical Speed Selector are mounted helter-skelter, just as the real world classic Learjets. 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. Thanks to its Pratt & Whitney Canada PW305A engines, the Learjet 60 has a total thrust output of 9,200 lbs. Exceptions may be granted. This mode is suitable for straight taxi, takeoff and gentle turns. Many times I receive offers or invitations to review a product and the offer comes at an inconvenient time mostly due to my haphazard work schedule. A drag chute is fitted as optional equipment on some Learjet 25 aircraft. My screen images are not as sharp as it should be but, I just cant seem to find to time to tweak it. However, it has been often at the cost of fuel efficiency. By the Numbers Recent Learjet sales is a very weak third place behind Cessna and Embraer. In terms of cost, the Learjet 60 has an estimated hourly charter price of $4,250. This explains why the extensions are constant chord. Embraer is the latest manufacturer entering the business jet market with the Phenom and Legacy lines of business jets. What is missing in the Manual? Additionally, the Learjet 60 has an average hourly fuel burn of 203 Gallons per Hour (GPH).

The flaps are hydraulically operated. The Lear loves to be at FL400. 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. The steering system on aircraft without variable authority nose wheel steering requires the pilot to select master or primary steering mode. 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. Interested in buying this aircraft click here. We all know the LearJet has gone through several iterations by 3 primary aircraft companies. Flapper-type check valves, located in the various wing ribs, allow free fuel flow inboard but restrict outboard flow. Hanger, insurance, service, unscheduled maintenance,de-icing, etc., you truly need to be prepared for the "real world" costs of ownership. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. Every conversation stressed the Learjets FAR 25, Transport Category certification, the very same certification level as a Boeing 747. fuel cost (one hour) Lear 24F $591.73 Lear 25D $721.92 Lear 35A $534.76 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 They even had the engine model numbers and thrust level properly identified. Our GLJ 25SE flight model does indeed have the updated BLEs instead of the older vortex generators. The best glide distance with engines windmilling is obtained with a clean airplane configuration and with a glide speed of 160 to 170 knots. When I asked, the developer about it, he agreed that Fuel Jettison would be a nice feature, but stated they have to draw the line someplace or they would never complete the package. WebThe Learjet 24 is an American twin-engine, high-speed business jet, which was manufactured by Learjet after the success of the Learjet 23. In case you just skipped over the CJ610 engine history, the highlights are that every production Model 20 series was powered by some version of the GE CJ610-1 through the CJ610-8A turbojet engine rated at 2,850 or 2,950 lbst. 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. 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. VRSURGEON also didn't state where his Family is, possibly not near a commercial field? On aircraft equipped with an auxiliary hydraulic pump, the hydraulic pump switch located at the lower centre of the instrument panel activates the auxiliary hydraulic pump to provide in-flight standby hydraulic pressure. 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. 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. With literally a thousand gallons of jet fuel, you will not be able to fly 2,000 nm at anything other than at a reduced economy cruise setting. Good luck. Taxi operations are accomplished using the electronic nose wheel steering. Thanks to its Honeywell TFE731-20BR engines, the Learjet 45XR has a total thrust output of 7,000 lbs. 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. I am in the business.been flipping large commercial jets to airlines for 15 years. - Aircraft specific reviews and articles. Here is a recent price break down from Business and Corporate Aviation magazine.

Photo: Charlie Gates on left, Harry Combs on the right. The GE CJ610-8A engines came directly from the military inventory. The good news is that you can download some excellent training manuals that have color illustrations, full systems descriptions and the necessary performance charts specifically for the Model 24/25 Learjet not all of them but the full pack for Mach 0.77). Search for the string learjet 24/25 MrMoo pdf. ). Both look like Learjets. A 25 will burn more fuel, of course, but that's only part of the equation. 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. This increased weight is significant because the additional 710 pounds aft gave Gates engineers a real cg problem that precluded a simple change of engines on the Model 25, as the original plan intended. Discussion in 'Aviation Chat' started by vrsurgeon, Aug 3, 2012. 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. Say on a 1 hour flight. Small stall strips were place on the leading edge with a newly designed stall fence. The bleed air is cooled in the heat exchanger by ram air entering the dorsal fin inlet and passing through the heat exchanger.

The fuselage tank can be filled by the wing boost pumps through the transfer line and the fuel transfer valve. Not much, but . (But the cargo door is still available as an option.) [2], Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on the aft fuselage. The original model 25 wing had a fairly sharp leading edge designed for high-speed cruise. The main gear is enclosed by two doors after retraction. It will also cost less to buy, and you won't have to pay MSP, but you will have to assume it will have only minimal residual value. Improved version. ( A jet pump installed in each tip tank transfers fuel into the wing tanks. The airplane was destroyed on the ground. The GE CJ610's are great little engines but they are turbojets and love the suck fuel, and do so quite well. 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. Sorry, sometimes I get carried away with this stuff. This is a significant step forward in providing an affordable, but yet sufficiently complex model of one of the many classic LearJets. The refrigeration system consists of a compressor, receiver dehydrator and evaporative cooler located above the baggage compartment. If the yellow disc is ruptured, either or both containers have been discharged into the engine nacelle. At idle on the ground a 20 series learjet will burn something like 150 +or- us gallons per hour. Two motor-driven shutoff valves will stop hydraulic flow to the engine-driven pumps in case of an emergency. Some of the animations only work either in the Lockheed Martin P3D edition or FSX, but, the performance and pleasure of flying a high performance classic Learjet with 3d gauges in an ultra HD virtual cockpit using our latest 3rd party avionics is outstanding. The CJ610-6 engines fitted to the Learjet 25 have very low inertia and accelerate rapidly. If you can't afford a used PC-12 you can't afford a flight department to run it.

The very first change was to replace the laid-back free-wheeling style of management with more professionalism for the sales team. It had the old Air Force engines on it. A used Lear @ $675,000USD will cost more than the savings on a PC-12 over the course of a year. 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. Each wing tank extends from the centre bulkhead outboard to the wing tip and provides separate fuel for each engine. 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 real world procedures are much easier than the simulated ones mostly due to the AP switches mounted on the control wheels in the real airplane not being accessible in our flight simulator add on. Please send us your experiences on your aircraft. A fuel control metering system selects the rate of fuel flow to the engine combustor.[3]. Fuel flow is indicated via a fuel flow system. 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. As good and as detailed and as beautiful as this GLJ Model 25s flight manual may be there is still room for improvement. I suggested the Empty Weight be reduced from 8,120 to 7,468 and the fuel load increased to 910 gallons. I tend you use the Honeywell name for the engines. I need something cabin class that is cheap to fly for about 1 hour legs. One click on the 8-Track tape player will start, move to the next selection, or stop the music. So, if the normal econ cruise is supposed to be M0.77-M0.78, the fuel burn modeled is definitely too high. 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 Bombardier Learjet 45XR can cruise at up to 51,000 feet. In 1974 the Peruvian Air Force purchased two 25Bs with a belly pod that contained an aerial survey camera. Panel space is naturally very limited in a classic Learjet, but an improved and very nifty one-click rotating choice of three gauge clusters is available. But first, they needed to stop the bleeding and improve the cash flow at their newly acquired Learjet factory. The 30 series have much more fuel efficient engines, not to mention quieter. I now have these items properly introduced and scheduled in my new more leisurely work schedule. When designing a new engine, they could add enough thrust to overcome the additional weight required to carry more fuel in more tanks, in this case only larger fuselage tanks to make a truly intercontinental range Learjet. 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.
