Larger turbine-powered helicopters can use anywhere between 20 to several hundreds of gallons of fuel per hour. However, air pressure and temperature both decrease with altitude, causing the maximum power or thrust of aircraft engines to reduce. With the winglets the drag factor is down -3.5%, not sure if the fuel burn is down the same number as in direct reduction also 3.5% (Different types of drag in affect) Reply 10th Jan 2009, 10:26 # 5 ( permalink) Deep and fast Join Date: Jan 2008 Location: another place Posts: 735 Likes: 0 This is useful when I need to balance the fuel in the main tanks with crossfeed. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Fixed some too high figures that relate to flights to the maximum distance and maximum load, also added some good old piston airplanes. If we stick to the previous example of the transatlantic crossing, one flight from London to New York, if operated by an Airbus A350 XWB, would cost over $55,000 in fuel. Are there tables of wastage rates for different fruit and veg? ", 2008 Guidelines to Defra's GHG Conversion Factors: Methodology Paper for Transport Emission Factors, "Records > Aeroplane efficiency > Current", "Fuel Efficient Plane Prototype Hits Skies", "Boeing to Begin Ground Testing of X-48B Blended Wing Body Concept", "AEDC testing brings unique blended wing aircraft closer to flight", "A sharkskin coating for ships, planes and blades", "Technology Roadmap for Environmental Improvement - Fact Sheet", "When Will These Civil Aircraft Concepts Fly? Its capabilities include: Longer range for presidential travel Aerial refueling Self-sufficiency at airports around the world Apart from the two bedrooms, it has a private guest room, dining room, and a video room with cinema system. Your email address will not be published. It projects the following reductions in engine fuel consumption, compared to baseline aircraft in service in 2015:[108], Moreover, it projects the following gains for aircraft design technologies:[108], Today's tube-and-wing configuration could remain in use until the 2030s due to drag reductions from active flutter suppression for slender flexible-wings and natural and hybrid laminar flow. As far as I know, in ISA conditions in long range cruise classics B733-5 would burn 1/23 of its weight per hour, while NG would burn 1/27 1/28 of its weight in hourly fuel flow. Thanks again. Boeing designed the 757 alongside and slightly behind the Boeing 767.The 767, which is a wide-bodied airliner, and the 757 share many of the same design features in . After A380s tests showing 12% savings, test flights were scheduled for 2020 with two A350s, before transatlantic flight trials with airlines in 2021. Smitty Former Military Veteran and Pilot for 35 Years Author has 51 answers and 13.6K answer views 9 mo Fuel consumption isn't measured use per hour like a car. Beyond single-engine taxi, electric taxiing could allow taxiing on APU power alone, with the main engines shut down, to lower the fuel burn. Large carriers, for example, have maintenance budgets in excess of $1 billion. 15 . [37], By taking advantage of wake updraft like migrating birds (biomimicry), Airbus believes an aircraft can save 5-10% of fuel by flying in formation, 1.52nmi (2.83.7km) behind the preceding one. 21 8 8.5 9 9.5 10 10.5 11 11.5 12 A subfield of fluid dynamics, aerodynamics studies the physics of a body moving through the air. Real world observations on 757-200 cargo. With eight years experience in publishing and citations in publications such as CNN, Linnea brings a deep understanding of politics and future aviation tech to her stories. Do I need a thermal expansion tank if I already have a pressure tank? Average fuel burn of new aircraft fell 45% from 1968 to 2014, a compounded annual reduction 1.3% with variable reduction rate. The fuel consumption of a Boeing 767-200 ER aircraft on a 7 hour flight is approximately 8,400 gallons. Why is this sentence from The Great Gatsby grammatical? depending on aircraft version, flight route and the nature of cargo. Minimising the environmental effects of my dyson brain. [36] Maintenance can also save fuel: 100kg (220lb) more fuel is consumed without an engine wash schedule; 50kg (110lb) with a 5mm (0.20in) slat rigging gap, 40kg (88lb) with a 10mm (0.39in) spoiler rigging gap, and 15kg (33lb) with a damaged door seal. An example is Singapore Airlines' former New York to Singapore flight, which could carry only 100 passengers (all business class) on the 10,300-mile (16,600km) flight. By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation; however, a higher cruise-speed allows more revenue passenger miles flown per day. [citation needed], Multiple concepts are projected to reduce fuel consumption:[110], The growth of air travel outpaces its fuel-economy improvements and corresponding CO2 emissions, compromising climate sustainability. [citation needed], Since early 2006 until 2008, Scandinavian airlines (SAS) was flying slower, from 860 to 780 km/h, to save on fuel costs and curb emissions of carbon dioxide. The lowest PIREP rate of fuel consumption was 62.5 pounds of fuel per hour. The impact of this additional fuel required by the A 330-200 for the projected 750 hours of [28], Fuel economy in air transport comes from the fuel efficiency of the aircraft + engine model, combined with airline efficiency: seating configuration, passenger load factor and air cargo. Fuel efficiency gains reduce the fuel carried, reducing the take-off weight for a positive feedback. It might be useful to have a "third axis" giving burn for a given range or the like. U.S. Navy Orders Up To 64 Beechcraft King Air 260 Turboprops For New Multi-Engine Training System, Gulfstream Completes 100th Delivery Of Award-Winning G600 Business Jet, Embraer Phenom 300 Series Tops Light Jet Class In Deliveries For 11th Consecutive Year, Following Seasonal Inventory Declines, Aircraft Asking Values Continue Year-Over-Year Growth. Why do small African island nations perform better than African continental nations, considering democracy and human development? The helicopter with the highest fuel consumption is the MIL MI-26. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. I did add all engine types where required. Again in 2016, the Aeroflot Group fuel consumption is 22.9g/ASK, or 2.86L/100km (82mpgUS) per seat, 3.51L/100km (67.0mpgUS) per passenger at its 81.5% load factor. I think GriN's post is regarding the earlier engines. [40] Late 1950s piston airliners like the Lockheed L-1049 Super Constellation and DC-7 were 1% to 28% more energy-intensive than 1990s jet airliners which cruise 40 to 80% faster. Their installation adds 200 kilograms (440lb) but offers a 3.5% fuel burn reduction on flights over 2,800km (1,500nmi).

Norwegian Air Shuttle was the most fuel-efficient airline on transatlantic operations in 2017, with an average fuel efficiency of 44 passenger-kilometers per liter of fuel (pax-km/L), 33% higher than the industry average. The Boeing warranty assures these figures will be met. For private aircraft in general aviation, current FAI Aeroplane Efficiency records are:[102]. Difference is, using ACC it literally took 10 minutes versus what would take me an hour + to do by hand. What video game is Charlie playing in Poker Face S01E07? I'm looking for the average fuel burn rates for a Boeing 757-200 at MTOW during the first hour of flight, and then the same, the average fuel burn rate for the second hour of flight. Asking for help, clarification, or responding to other answers. The easy elements to capture are the APU fuel consumption values. [citation needed]. I think the B757 burns appreciably more fuel than an A320, in fact I believe it's around 1,000 kg/hr more at MTOW. In the late 2000s/early 2010s, rising fuel prices coupled with the Great Recession caused the cancellation of many ultra-long haul, non-stop flights. Every type from fighters to helicopters from air forces around the globe, Classic Airliners For the A350-100, this is approximately 6400 kg / h for 787-10 about 5700 kg / h in normal operation for long haul. [109] I think i know how to work out how much fuel is used for an overall distance, but not sure how i would work out how much fuel is used during a cruising hour? Most aircraft have vast reserves for storing fuel, with the A350 capable of carrying over 37,000 gallons. Continuous Descent Approaches can reduce emissions. [45] [38] "It's with my pleasure to refer Jack Prewitt to your service, which we have found to be accurate, straightforward and of real benefit to our clients. The weight savings in both allow for a lighter fuel load for a given range and payload. The actual amount of fuel varies based on the load of the plane. In 2012, turboprop airliner usage was correlated with US regional carriers fuel efficiency. [20] [51] In terms of fuel burn per mile, with the A330 as a baseline and assuming the TU144 flies at the same speed as Concorde: -. The standard number was 25,000 lbs per hour. [34][35], Airbus presented the following measures to save fuel, in its example of an A330 flying 2,500 nautical miles (4,600km) on a route like BangkokTokyo: direct routing saves 190kg (420lb) fuel by flying 40km (25mi) less; 600kg (1,300lb) more fuel is consumed if flying 600m (2,000ft) below optimum altitude without vertical flight profile optimization; cruising 0.01 mach above optimum consumes 800kg (1,800lb) more fuel; 1,000kg (2,200lb) more fuel on board consumes 150kg (330lb) more fuel while 100 litres (22impgal; 26USgal) of unused potable water consumes 15kg (33lb) more fuel. And while significant investments are being made to increase that, it will still be a long way to go before we start seeing it deployed in amounts that will have an impact on overall emissions and other numbers. Over the transatlantic route, the most-active intercontinental market, the average fuel consumption in 2017 was 34 pax-km per L (2.94L/100km[80mpgUS] per passenger). A Boeing 757 burns around 2,000 pounds of fuel during take off. Aircraft Cost Calculator frees you from your desktop to offer a mobile solution you can access anywhere in the world. A 747 uses 5 gallons of fuel to carry 500 people one mile. This is 183,214 to 216,847 liters of fuel or about 180 to 213 tonnes. The International Air Transport Association (IATA) technology roadmap envisions improvements in aircraft configuration and aerodynamics. According to Boeing's website, the 747 consumes about 5 gallons of fuel each mile (12 liters per . just checking. NASA indicates this configuration could gain up to 45% with advanced aerodynamics, structures and geared turbofans, but longer term suggests savings of up to 50% by 2025 and 60% by 2030 with new ultra-efficient configurations and propulsion architectures: hybrid wing body, truss-braced wing, lifting body designs, embedded engines, and boundary-layer ingestion. How can I calculate the fuel consumption of an Airbus 320-200 at various loads? A Boeing 737-400 jet is typically used for short international flights. In Europe in 2017, the average airline fuel consumption per passenger was 3.4 L/100 km (69 mpg US), . For example, the Airbus A350 design includes a majority of light-weight composite materials. When taking into account the number of passengers onboard, the efficiency is advertised by Airbus at 120 miles per gallon (MPG). So a 10 flight would burn approximately 250,000 lbs of fuel. Aviation Fuel: 100-Low Lead Aviation Fuel: 100 Octane Automotive Gasoline (thous gal) Total Fuel Use Other Fuel AVERAGE FUEL CONSUMPTION RATE BY AIRCRAFT TYPE Fixed Wing: Piston Fixed Wing: Turboprop Fixed Wing: Turbojet Rotorcraft: Piston Rotorcraft: Turbine Jet Fuel: Turbine Columns may not add to totals due to rounding. 160 KIAS may exceed allowable tire rotation speed. Updated for Q4 of 2022 the average price of jet fuel from a typical FBO in the United States is currently hovering around $7.50 per gallon. Meanwhile, one of the key factors in getting a plane from point A to point B is the amount of fuel that it needs to get there. A jet aircraft uses a phenomenal amount of fuel. [16] . [46] Embraer delivered 59 Phenom 300-series aircraft last year and has completed more than 700 deliveries since the 300 entered the market in 2009. Compare unlimited number of aircraft side-by-side. This equates to roughly 1 gallon (approximately 4 litres) of fuel every second. A reduction in airframe weight enables the use of smaller, lighter engines. The Boeing 757 is a low-wing twin-jet airliner that was produced by Boeing Commercial Airplanes from 1981 to 2004. Capabilities and Features - Current Presidential Airplane (Boeing 747-200) Today, the chief executive flies aboard a specially configured 747-200B, the newest and largest presidential airplane. Efficiency is increased with better aerodynamics and by reducing weight, and with improved engine BSFC and propulsive efficiency or TSFC. For powered aircraft, the optimum glide ratio has to be balanced with thrust efficiency. Loading information Loading compartments, main and lower deck. I know on paper the PW have that advantage, but actual performance wise, the RRs win. Every second, a Boeing 747 consumes around 1 gallon of fuel (about 4 liters). [39], Modern jet aircraft have twice the fuel efficiency of the earliest jet airliners. If you have a range for each period, that be cool as well. Live Chat for any questions you may need answered. The aircraft's maximum range is determined by the level of efficiency with which thrust can be applied to overcome the aerodynamic drag. Every airliner carries considerably more people than the average car; in the case of the Boeing 747, its 568 in total. Photos taken by airborne photographers of airborne aircraft, Special Paint Schemes As well as bringing large jet ranges to a medium-sized jet, the Boeing 787 also matches the speeds of larger jets with a cruise of Mach 0.85. How do i do it in excel? improves the fuel efficiency per unit of mass moved. Why is there a voltage on my HDMI and coaxial cables? Jetliner fuel efficiency improves continuously, 40% of the improvement come from engines and 30% from airframes. Thanks again! vegan) just to try it, does this inconvenience the caterers and staff? The technical storage or access that is used exclusively for statistical purposes. The amount of fuel an aircraft buns per hour depends on the weight of the aircraft, its altitude and the speed it is maintaining. If you are looking for a specific thing you are looking for, please let me know. Would you know the service ceiling and the max certified altitude? NASA and Boeing flight-tested a 500lb (230kg) blended wing body (BWB) X-48B demonstrator from August 2012 to April 2013. Aircraft flying government officials, Helicopters Designed for owners, operators, flight departments, financial institutions and charter operators. That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel. To minimize fuel consumption, an aircraft should cruise close to the maximum altitude at which it can generate sufficient lift to maintain its altitude. How much carbon dioxide does an airplane create? In 2018, the US airlines had a fuel consumption of 58mpgUS (4.06L/100km) per revenue passenger for domestic flights,[21] Social login does not work in incognito and private browsers. After all, there is a reason that the aircraft manufacturers provide charts to calculate such things, and not hard numbers. Uplift capacity range is from 34 tons to 36 tons. It was my understanding that its the other way around. What is the point of Thrower's Bandolier? Im not a pilot but what is the two take-off field lengths for? Your email address will not be published. [109] ", "ACC was key in my initial work to build my business model and validation process. What is the fuel consumption of a Boeing 767 . In Europe in 2017, the average airline fuel consumption per passenger was 3.4L/100km (69mpgUS), 24% less than in 2005, but as the traffic grew by 60% to 1,643 billion passenger kilometres, CO emissions were up by 16% to 163 million tonnes for 99.8 g/km CO per passenger. For example, a Boeing 777-300 reaches that point at 3,000 nautical miles (5,600km). Aircraft Fuel Consumption With 268.6 total hours of flight time. Efficiency gains were larger early in the jet age than later, with a 55-67% gain from 1960 to 1980 and a 20-26% gain from 1980 to 2000. every 5 miles per hour your drive over 50mph is the equivalent of paying $0.19 more for each gallon of gas. This equates to around $46,000 for the flight. hmmm?? Airbus states a fuel rate consumption of their A380 at less than 3 L/100km per passenger (78 passenger-miles per US gallon). Without your data, I don't think I ever would have been able to convince myself and those supporting me to do this.". Pre-loaded data (fully editable by the user) based upon owners, operators, and fleet managers actual expenses accessible on any device. Do you know the tailplane dihedral? And max G loading for which I am looking. Currency Conversion & Imperial to Metric Units at the click of a button. From the early stages of airplane development, the 737-600/-700/-800/-900 team strove to lower maintenance costs and give the airlines the airplane with the most competitive operating cost possible. Each gallon of JP8 - Kerosene - or jet fuel, weighs about 6.5 pounds. Im doing a comparison between the 737-800 and the 757-200 and there is some data missing. Washington Dulles Seattle-Tacoma is 2,000 nmi) to short transatlantic flights (e.g. Our Boeing 727-200 consumes a calculated average of 8660.4 pounds of fuel per hour. This 3,300 km route coincides with the real commercial route Tu-144C Moscow-Almaty, the flight time was 2 hours, trip fuel 76.5 tons, headwind 80 km / hour. Compare these figures for the A350-1000 with 777-300ER, meanwhile they are both twins with high-tech high bypass engines with the same capacity and size. "Trip Cost Calculator" which can clearly show the cost savings associated with business aviation versus commercial travel - including the Time Value of Executives. First Hour (includes takeoff, climb to optimum altitude, does not include start/taxi fuel, usually about 250 kgs): 3870 kgs. The Boeing 757-300 is short-to-medium-range jetliner, launched in Sept. 2, 1996, with an order from Condor Flugdienst. So up front, I'm aware of the high number of aircraft and environmental factors and how oversimplified my request is. Does any one know how the official fuel burn/seat is calculated? The leading independent voice for aviation news and insight. In 2015 Ryanair emitted 8.64Bnt of CO2 for 545,034 sectors flown: 15.85t per 776mi (674nmi; 1,249km) average sector (or 5.04t of fuel: 4.04kg/km) representing 95kg per 90.6million passengers (30.4kg of fuel: 3.04L/100km or 76gCO2/km). For a distance of 926 km, the amount of fuel used is estimated to be 3.61 tonnes [1], including taxiing, take-off, cruising and landing. [29], In 2018, CO emissions totalled 918 Mt with passenger transport accounting for 81% or 744 Mt, for 8.2 trillion revenue passenger kilometres:[30] an average fuel economy of 90.7 g/RPK CO - 29 g/km of fuel (3.61L/100km[65.2mpgUS] per passenger), In 2019, Wizz Air stated a 57 g/RPK CO emissions (equivalent to 18.1 g/km of fuel, 2.27L/100km[104mpgUS] per passenger), 40% lower than IAG or Lufthansa (95 g CO/RPK - 30 g/km of fuel, 3.8L/100km[62mpgUS] per passenger), due to their business classes, lower-density seating, and flight connections.[31]. That may be true, but the problem with the TU-144 engines (certainly the early ones) was they were turbofans, not turbojets like Concordes. Productivity including speed went from around 150 ASK/MJ*km/h for the 1930s DC-3 to 550 for the L-1049 in the 1950s, and from 200 for the DH-106 Comet 3 to 900 for the 1990s B737-800. All these numbers! According to an industry analyst, "It [was] pretty much a fuel tanker in the air. The 747-8 passenger plane can carry up to 422,000 pounds of jet fuel, or 63,034 gallons. Rising fuel prices are also in the news as a result of the war in Ukraine. Most of the (extremely) generic references I've seen using that metric for a Boeing 747-400 are in the US$25,000 per hour range. [104] The BWB concept offers advantages in structural, aerodynamic and operating efficiencies over today's more-conventional fuselage-and-wing designs. Two NASA experiments designed to help reduce fuel consumption and emissions will fly this spring on a specially outfitted Boeing 757 airplane called the ecoDemonstrator. [15][need quotation to verify] The Bombardier Dash 8 Q400 turboprop is used for this reason as a regional airliner. Published Jun 12, 2010. When this is taken into consideration, a Boeing 747 is, in fact, burning only 0.01 gallons per person onboard for every mile that it travels. With a specifically designed aircraft, such as the (in development) Aerion AS2, the Mach1.1 range at 3,700nmi is 70% of the maximum range of 5,300nmi at Mach0.95, but increases to 4,750nmi at Mach1.4 for 90% before falling again. Induced drag can be reduced by decreasing the size of the airframe, fuel and payload weight, and by increasing the wing aspect ratio or by using wingtip devices at the cost of increased structure weight. But under FAA and EASA regulations, the Captain of an aircraft is responsible for ensuring that it has enough fuel before taking off. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? In 2014, MSCI ranked Ryanair as the lowest-emissions-intensity airline in its ACWI index with 75g CO2-e/revenue passenger kilometre below Easyjet at 82g, the average at 123g and Lufthansa at 132g by using high-density 189-seat Boeing 737-800s. An aircraft weight can be reduced with light-weight materials such as titanium, carbon fiber and other composite plastics if the expense can be recouped over the aircraft's lifetime. Unfortunately, sustainable aviation fuel (SAF) still accounts for only 0.1% of all jet fuel usage globally. Accident, incident and crash related photos, Air to Air You can learn all about the cost to own a private jet here. Second hour: 7680 kgs; Third hour: 11,160 kgs; Fourth hour: 14,880 kgs; Fifth hour: 18,750 kgs; Sixth hour: 22,860 kgs; Seventh hour: 26,880 kgs; Eighth hour: 30,960 kgs. Boeing 747 uses approximately 4 litres every second, which translates to 240 litres per minute and 14,400 litre per hour For a 13-hour flight from Tokyo to New York City , Boeing 747. The technical storage or access that is used exclusively for anonymous statistical purposes. This included the services provided by Singapore Airlines from Singapore to both Newark and Los Angeles that was ended in late 2013. As parasitic drag increases and induced drag decreases with speed, there is an optimum speed where the sum of both is minimal; this is the best glide ratio. Comfort would not be affected and trials are limited to two aircraft to reduce complexity but the concept could be expanded to include more. Does Counterspell prevent from any further spells being cast on a given turn? Second. The 757-200 burn is probably around 9,500 lbs per hour. It only takes a minute to sign up. The average block fuel intensity of new aircraft decreased 41% from 1970 to 2019, and that is a Interesting enough was the page with an example of flight planning. There was also the Tu-144D with more economical turbojet Kolesov RD-36-51 without afterburner at supersonic speed, but it did not perform any commercial flight while the cruising fuel flow was about 25000 kg / h. Engines have always been the weakest point of Soviet aircraft. Airliners.net is the leading community for discovering and sharing high-quality aviation photography. No wonder passenger airlines have waved goodbye to the Queen of the Skies in favor of twinjet widebodies. New technology can reduce engine fuel consumption, like higher pressure and bypass ratios, geared turbofans, open rotors, hybrid electric or fully electric propulsion; and airframe efficiency with retrofits, better materials and systems and advanced aerodynamics. Is the A300 figure from a first-gen B2 or a later-gen -600? A jet aircraft uses a phenomenal amount of fuel. height: 132 4.01 mtr NASA has conducted an Advanced Turboprop Project (ATP), where they researched a variable-pitch propfan that produced less noise and achieved high speeds.[19]. [2] A 88 gCO/km represents 28 g of fuel per km, or a 3.5L/100km (67mpgUS) fuel consumption. But the comparison is not as simple as it might seem initially. Did I witness an engine test for a 757 at MAN? Good info too bad we have to convert much of it from metric here in the States. For a given payload, a lighter airframe generates a lower drag. At a macro level, aircraft operating costs include both flight . Its 92,000-pound (41,731 kilogram) fuel capacity allows the aircraft to travel 5,500 nautical miles unrefueled. one for one type of Pratt=Whitney engines and the other for another type of Pratt whiteny engine? Airline Aircraft Block Hour Seat Hour (hrs/day) (Miles) Boeing 757 . Beautiful shots taken while the sun is below the horizon, Accidents Our large helicopter section. A more realistic passenger load is 90 per cent, in which case fuel consumption per passenger is 2.2 litres/100km. Brooks says a DC-3 with 1200-hp R1830s cruising at 550 hp per engine at 6000 ft will burn 490 pounds/hour. While several more fuel-efficient aircraft are traversing the skies today, a Boeing 747 quadjet burns up to one gallon of fuel every second. How many hydraulic systems does the Boeing 757 series have? Yes, this is an example for the Tu-144S with NK-144 engines with the afterburner on the cruise. [113], Last edited on 26 February 2023, at 15:25, Learn how and when to remove this template message, Continuous Lower Energy, Emissions and Noise, "CO2 emissions from commercial aviation, 2018", International Council on Clean Transportation, "Dubai 09: A320s sharklets to deliver 3.5% lower fuel burn from 2012", Why the Longest Nonstop Flights Are Ending, "SIA to drop nonstop USA flights as Airbus buys back A340s", "Last Call for the Long Haul From Singapore to Newark", "A new era of 'ultra-long-haul' aviation", "Effect of Fuel Properties on the Specific Thrust of a Ramjet Engine", "Back to the Future: Return of the Turboprop? This article is part of a directory: Farnborough Airshow 2022: As It Happens Table of contents. What is the fuel capacity of a Boeing 757? When you start to examine the numbers, they start to get pretty big, pretty quick. If you need variables to run the calculation, I offer the following: Temp: 59 F/ 15 C Altimeter Setting: 29.92 In-Hg/ QNH 1013 Final, Cruising Alt: FL380 Assume standard takeoff configuration and initial climb performance. Both military and civil versions, Blimps / Airships Boeing 767 and Airbus 330 Fuel Consumption Analysis (High TOGW) - Commercial Service Conklin & de Decker Aviation Information (November 12, 2007) 5 This shows clearly that the Airbus 330-200 burns about 24% more fuel per hour than the Boeing 767-200ER. In fact, the 747-8 burns roughly like 747-400 about 10,300 kg / h but takes more passengers. The Boeing 757 is known for its improved fuel efficiency and reduced noise levels, and will be phased in over time as the less fuel-efficient Boeing 727 aircraft are retired from service. "I want you to make your investigation first.""Look at me close," I said."You knew this long ago!" she cried accusingly. Thanks in advance! As far as I can understand, they cannot make sense without a speed/distance/payload context. This would make airlines far more attracted to buying the A220 over the Boeing 737 as the price of fuel goes up. The MAX9 shows an improvement in fuel costs of nearly 12% over the 737-900ER. Endurance and range can be maximized with the optimum airspeed, and economy is better at optimum altitudes, usually higher. [8] For these reasons, the world's longest commercial flights were cancelled c.2013. In 2021, the highest seating density in its A330neo, with 459 single-class seats, enabled Cebu Pacific to claim the lowest carbon footprint with 1.4kg (3lb) of fuel per seat per 100km,[32] equivalent to 1.75L/100km[134mpgUS] per seat. [18] Propfans bridge the gap between turboprops, losing efficiency beyond Mach 0.5-0.6, and high-bypass turbofans, more efficient beyond Mach 0.8.
