Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on the aft fuselage. Trim functions, microphone keying, autopilot override and steering system switches are located in the control wheels. Although no longer in production, the iconic Learjet 70/75 pair are still sought-after, mid-sized business jets. WebThe price includes fuel burn and various maintenance, crew, and operational fees. The Flysimware Lear lets you take her up to FL420 and higher even when fully loaded. When it comes to fixed costs, there are six criteria that have been identified as the biggest contributors to the annual cost of operation. Spirit Wing also removed from the SpiritLear the rear fuselage fuel bladder from the original Learjet 25. Note that FltPlan.com is primarily for real world flight planning. 
The Learjet 70 and 75 are so alike that they are often grouped together as the Lear 70/75, almost as though they are one aircraft. Two spherical fire extinguisher containers can discharge their contents to either engine. 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, exha When it comes to operating the Bombardier Learjet 31, there are two expense categories to consider fixed costs and variable costs. After spending years watching every video I could find about flying, I finally scratched the itch and got my pilots license. The first customers had their aircraft delivered in late November 2013, the same month it received its FAA type certificate. If there will be days when you are not using your Learjet 70 or 75 yourself, you might consider hiring a jet management company to hire out the aircraft, and manage its maintenance schedule. 
Cleared for a straight-in on 19 Right, he crossed the end at ref speed and used only 2,000 feet to stop before turning off toward the Lear factory ramp. The Bombardier Learjet 31 can cruise at up to 51,000 feet. The Lear 70/75s engines run on Jet A-1, which costs approximately $7 per gallon in the USA. The large display panels give the flight deck environment a modern, uncluttered look. 
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 Therefore, the estimated hourly variable rate for operating the Bombardier Learjet 31 is $2,181. Storage is an important element to consider given that your aircraft will need to be waiting somewhere safe and secure when it isnt in the air. There are typically provided by the FBO (fixed-base operator). The fuel flow through a rotor-turbine at each engine causes the rotor to spin and a pickup coil emits pulses as the rotor blades pass through the coil field. And aviation is my passion, he said. FAA certified on September 4, 1970.
Many Learjet 25 aircraft remain in regular use today, particularly in the United States, Mexico, and Canada. 
Although there is a cost associated with hiring a jet management company, the revenue brought in by renting your airplane to third parties should more than cover it. The tip tanks provide additional fuel capacity to enable longer times aloft. Although no longer in production, the iconic Learjet 70/75 pair are still sought-after, mid-sized business jets. WebLear Corporation is an American company that manufactures automotive seating and automotive electrical systems. I, too, think that what we already have is a fine and thoroughly enjoyable representation of the Lear 35A, otherwise I wouldn't bother spending that amount of time with it. The drag chute is attached to the aircraft with a lanyard system that releases it from the aircraft should an inadvertent deployment be made while airborne. Also apparent are the winglets, which increase efficiency by preventing energy-wasting drag as air flows along the wingspan. Aviation hull war insurance provides cover for loss of the aircraft due to war, hijack, confiscation, malicious damage and other similar risks. Start at which flight level? Interestingly, the cabin management system utilized on the Lear 70/75 was developed by Lufthansa Technik to be equipped on smaller aircraft but were slightly modified for the Lear 70/75 following a deal between them and Bombardier Learjet when the two models entered production. The stall speed of both the Learjet 70 and 75 is 120 knots, which is quite high for an aircraft of its size. Additionally, these maintenance events are in direct relation to the number of hours that the aircraft is flown. The bleed air is cooled in the heat exchanger by ram air entering the dorsal fin inlet and passing through the heat exchanger. This is a much higher standard than the Part 23 regulations that most of the Learjets competitors follow. The seats can be reclined to form berths if required. Like almost all airplanes, the Lear 70/75 has wing fuel tanks. thanks for the info. Should the fuels begin to solidify in flight because of low temperature, it can cause serious issues in the final approach phase of flight when the engines need to provide power to overcome drag caused by extended wing flaps and lowered landing gear. Fixed costs are those that you pay no matter what. Making the turn over Houston, we climbed to FL410, where fuel flows dropped to about 400 pounds per side. The electrically operated RPM tachometer consists of a signal generator on the engine and an indicator located in the centre of the instrument panel. WebThe fuel burn calculations performed by Bombardier and the data submitted to Eurocontrol may differ with fuel burn and emissions calculations performed using 3rd party A pre-charged accumulator dampens and absorbs pressure surges. The only way to acquire a Lear 70/75 is on the secondary market. Engineers placed the new hydraulic lines under the Williams powerplant. Landing fees will vary from airport to airport. The Learjet 70 and 75 boasts a very quiet passenger cabin, thanks to excellent sound insulation and a pocket door separating the cockpit from the cabin.

A Cessna Citation CJ2 will cost a new owner about $5.2 million and fall about 150 nm short of the SpiritLears range while cooking along at only 407 knots on 159 gallons/1,065 pounds of fuel per hour. WebThe key difference is the additional two feet of fuselage length that the 75 has over the 70, accommodating an extra passenger, but slightly reducing the maximum range and maximum payload, with a minimal increase in fuel burn. The Lear 70/75 is a medium sized private jet, able to seat seven (Lear 70) or eight (Lear 75) in standard configuration and two flight crew. The rudder pedals mechanically operate the rudder for directional yaw control. Sign up for a new account in our community.
This means everything stays hot, even during a descent with the throttles at idle. They may have modded the fuel flow from when I looked at it back then.I'll have to check it again but spring has sprung and dusting off the warm weather activity stuff right now is getting the priority ! 
This should be close enough and should go well with the "rule of thumb" observed for the 1.50 value which was still a bit too high. Numerous modifications have been made over the past fifty years, improving efficiency and performance. The nose wheel has a specially moulded tire to prevent water splashing into the engines. Or we could try to tweak the fuel_flow_scalar in the .cfg file outselves if we knew by how many percent the Flysim fuel burn is off the real thing. The flight instruments comprise Garmin G5000 avionics with touchscreen control, giving pilots easy access to the primary flight display (PFD) and navigational display. 
Bombardier launched the Lear 70/75 in the early 2010s and following a prolonged development process, they replaced their predecessors in production. Compared with similar aircraft, the Lear 70 and 75 weigh more, and use more fuel. For the seats adjacent to the emergency exit, a detachable table is provided, which can be stowed behind the rear seats when it is not in use. I generally cruise at .72 to ,73 mach. The Lear 70 and 75 are certified under FAA Part 25 regulations, which means the Learjet has to follow the same rules as larger jet airliners. As for the flight level profile during this long-range cruise, what would you suggest? , the total annual budget for a Learjet 75 flying 450 hours per year is $1,639,408. What is your primary motivation for flying by private jet? Primarily the difference in cost will depend on the aircraft type, use and region of operation. Therefore, it is good practice to factor in additional, unexpected costs per year. In 1970 the Learjet 25B was produced along with the Learjet 25C in the same year. Type development continued with the Models 25D and 25G, which included more advanced CJ610-8A engines and a ceiling increase to 51,000 feet. By 2018, 1970s Learjet 25s were sold for under $200,000. An audible waning horn warns of flap extension to more than 25 degrees if the landing gear is not down and locked. At this speed, the Learjet 25 glides approximately 26 nautical miles for each 10000 feet of altitude loss. This work required modifying the front engine mount while constructing an entirely new rear engine support structure. Tables can be fitted in the space between facing seats, except in front of the emergency exit. 
Cruising at FL450 (45,000 feet), the air conditioning and pressurization system maintains the cabin altitude at a super-comfortable 6,000 feet, and the Lear 70/75 can accomplish this with one engine throttled back to idle if necessary. Unfortunately, Oklahoma City departure kept the airplane level there for some three minutes before Burgess pushed the throttles ahead for the next segment of the climb, which took us unrestricted to FL370. 
The H-valve position can be adjusted by the crew to increase or reduce the amount of bleed air cooling at the heat exchanger. To get the best range, however, pilots will usually let the gauge settle back to a more economical cruise of Mach 0.76. Burgess occupied the left seat, with company test pilot Neil Brown in the right. Are your plans likely to change or cancel within 12 hours of departure? The estimated annual fixed cost for operating the Learjet 31 is $316,617. Based on current and historical sales prices, a used Lear 70/75 will set you back between $5.5 and $9.25 million, The Lear 70/75 has a top speed of 465 knots. Improved version. With a cruising speed of approximately Mach 0.76, passengers reach their destination in good time. Although piping fuel - from the fuselage tank to the wings, then back through the fuselage to the engines - might be considered a safety concern, because of the possibility of a post-accident fire, the Learjet has proven itself to be a remarkably safe aircraft.

Use a full pax/cargo/baggage load? One point the Lear 70 scores over the 75 is internal baggage space. Passengers can access separate movies and music. The cabin interior can be converted to several different configurations to allow for cargo and medevacs. Regarding the FSW version I tried a trip a about three months agowith full fuel and .77 cruise at 390 and was out fuel about 3+45 into it.I actually prefer to sim with old piston engine stuff but try an endurance flight with full fuel and note the hourly fuel burn off until you hit dry tanks.If you can't get 4+45 or better something is not right. However, in most cases aircraft spend the evenings at their home base. The Lear 70/75s flight controls are conventional in layout, with twin control columns, each with a w-configuration control wheel. Therefore, the more hours flown, the quicker an engine overhaul will be required.

The engines fitted to the Lear 70/75 are derated from their maximum performance parameters, which extends their life and reduces maintenance costs. Additionally, crew fees are highly dependant on the length of stay and the location. Aircraft management is an essential component when owning and operating a private jet.
Airspeed indication is provided by a single pointer, dual scale airspeed/ mach meter. It is possible for gravel from an improperly packed gravel runway to be sucked into the engines causing "foreign object damage", thus the need for the kit. (e.g. The cabin pressure is provided by the conditioned air entering the cabin through the distribution ducts and controlled by modulating the amount of air exhausted from the cabin.
Of course, this hourly variable cost is different to that of the estimated hourly charter price. Two disc-type indicators are flush mounted under the left engine. Of course, all these services will come at a price. WebThe Lear 31 Small Jet was manufactured by Learjet Inc between 1987 and 2003. An integral anti-skid system in installed to affect maximum braking efficiency.
Furthermore, back when deliveries of the Bombardier Learjet 31 began, the list price for a new example was $4.5 million. In the center of the main panel, another large display shows power plant parameters and navigational data, the format of which can be selected by the flight crew. Burgess said the aircraft offers more speed, range and payload than many new designs that cost millions of dollars more. In SpiritWing-provided data, the company says the SpiritLear will carry four people 1,705 nm while burning 128 gallons/858 pounds per hour at speeds up to 440 knots.
