Thanks for contributing an answer to Aviation Stack Exchange! A 747 uses 5 gallons of fuel to carry 500 people one mile. Moderators: richierich, ua900, PanAm_DC10, hOMSaR, Military Aircraft Let's call it 500 people to make the math easier. Our large helicopter section. If you have a range for each period, that be cool as well. Specific fuel consumption of air-breathing jet engines at their maximum efficiency is more or less proportional to exhaust speed. 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. As far as I can understand, they cannot make sense without a speed/distance/payload context. That means the jetliner is ultimately nearly twice as fuel-efficient as a car carrying one person.

According to your info, the PWs cause the 757 to have greater range then the RR powered ones. looking to purchase some stairs to fit the 757, no stats on ground to door sill ? [citation needed], To get thrust, an aircraft engine is either a shaft engine piston engine or turboprop, with its efficiency inversely proportional to its brake-specific fuel consumption coupled with a propeller having its own propulsive efficiency; or a jet engine with its efficiency given by its airspeed divided by the thrust-specific fuel consumption and the specific energy of the fuel. But under FAA and EASA regulations, the Captain of an aircraft is responsible for ensuring that it has enough fuel before taking off. I know on paper the PW have that advantage, but actual performance wise, the RRs win. [42] 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. New York JFK London-Heathrow is 3,000 nmi). As a non aeronautical person, who is mildly OCD and loves reading lists (and phone books), I found it very interesting that an A350 burns through 5800kg/hr, and a B748 9800kg/hr, for a pretty equivalent passenger load. In 2013, the World Bank evaluated the business class carbon footprint as 3.04 times higher than economy class in wide-body aircraft, and first class 9.28 times higher, due to premium seating taking more space, lower weight factors, and larger baggage allowances (assuming Load Factors of 80% for Economy Class, 60% for Business Class, and 40% for First Class).[22]. NASA and Boeing flight-tested a 500lb (230kg) blended wing body (BWB) X-48B demonstrator from August 2012 to April 2013. A jet aircraft uses a phenomenal amount of fuel. ", 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? Both military and civil versions, Blimps / Airships In 2018, the US airlines had a fuel consumption of 58mpgUS (4.06L/100km) per revenue passenger for domestic flights,[21] Aircraft flying government officials, Helicopters The target for overall reduced airframe maintenance costs was 15 . The aviation fuel density used is 6.7lb/USgal or 0.8kg/L. Its two 11,000 . I did add all engine types where required. It might be useful to have a "third axis" giving burn for a given range or the like. For example, fuel consumption and flight time, it is not difficult to calculate the average fuel consumption in US gal/hr. You can study the effects of any engine component's performance on fuel consumption and compare the efficiency of various types of turbine engines. Published by Laia and Pierre-Selim on Jul 31, 2018 10:07:00 AM. Trump pays a lavish price for these amenities and shells out about $10,800 for a one-hour flight including fuel. Every airliner carries considerably more people than the average car; in the case of the Boeing 747, its 568 in total. The tough ones to capture are the APU capital costs and maintenance costs. Air density decreases with altitude, thus lowering drag, assuming the aircraft maintains a constant equivalent airspeed. Hi Steve, For widebodies the range of fuel burns is as massive as the range of weights. Certification for shorter separation is enabled by ADS-B in oceanic airspace, and the only modification required would be flight control systems software. Fully editable pre-loaded "real world" data for over 500+ aircraft - piston, turboprop, jet, & helicopter available in ONE application. 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. 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). how it is calculated with respect to wing dimensions. [49][verification needed] Sorted by: 11 The following table shows the long range cruise control data for a Boeing 737-800 (source: FCOMv1 Performance Inflight - All Engine PI.31.2): Let us consider a typical cruise at FL370 with a weight of $ 65 \, \mathrm {t} $. That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel. https://www.transportenvironment.org/si ciency.pdf, https://www.fs.fed.us/fire/contracting/ 1-2013.pdf, https://www.fs.fed.us/fire/contracting/ rs_cwn.htm, https://www.icao.int/environmental-prot 9_2016.pdf, http://www.saabaircraftleasing.com/prod 00_jar.pdf, http://www.sasgroup.net/en/airbus-a319- -a320a321/. How many hydraulic systems does the Boeing 757 series have? Boeing 747 - $153 million. You can learn all about the cost to own a private jet here. Compare unlimited number of aircraft side-by-side. When taking into account the number of passengers onboard, the efficiency is advertised by Airbus at 120 miles per gallon (MPG). And max G loading for which I am looking. [8] For these reasons, the world's longest commercial flights were cancelled c.2013. Why didn't the Boeing 757 share the 767 fuselage? Knowing the maximum range and weight of the aircraft, it is easy to calculate the fuel consumption of A350-1000 and 787-10. Understand how financing, capital cost considerations, residual values, and lease payments affect your operating costs. Large, ultra high bypass engines will need upswept gull wings or overwing nacelles as Pratt & Whitney continue to develop its geared turbofan to save a projected 1015% of fuel costs by the mid-2020s. Good info too bad we have to convert much of it from metric here in the States. For example, even the super-fast turboprop Tu-114 on the route equivalent to LHR - JFK would have burned 45,400 kg at cruise M0.725 according to the norms of the Ministry of Aviation of the USSR. 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. As such, we thought it would be a good time to look into exactly how much fuel an airliner needs to fulfill some of its most common missions. [13][need quotation to verify], Turboprops have an optimum speed below 460 miles per hour (740km/h). Thats why RR powered 757s are more preferred for over the pond flights. [38] For private aircraft in general aviation, current FAI Aeroplane Efficiency records are:[102]. [16], Jet airliners have become 70% more fuel efficient between 1967 and 2007. As a result, how much fuel per passenger an aircraft is consuming is one of the most important . Here's the equation: 2 C 8 H 18 + 25 O 2-> 16 CO 2 +18 H 2 0. [45] This equals approximately 14,000 gallons of fuel for a flight between New York Newark (EWR) and London Heathrow (LHR) of just over 3,000 NM. Compare that to the average motor vehicle. Its maximum take-off weight is nearly one million pounds. Boeing 757-300: 1998: 243: 500 nmi (930 km) 5.19 kg/km (18.41 . An airline efficiency depends on its fleet fuel burn, seating density, air cargo and passenger load factor, while operational procedures like maintenance and routing can save fuel. By 2030 hybrid-electric architectures may be ready for 100 seaters and distributed propulsion with tighter integration of airframe may enable further efficiency and emissions improvements. per hour: $19,432 - per nautical mile: $46.97 - per nautical seat mile: $2.47 Source: Conklin & de Decker, Orleans, Mass. Why is there a voltage on my HDMI and coaxial cables? For powered aircraft, the optimum glide ratio has to be balanced with thrust efficiency. Back in the day, Capts on our 747-200s would make a reasonableness check on the flight plan as part of his pre-flight. I don't think I buy that a DC-8-63 burns less than a 707-320B. Connect and share knowledge within a single location that is structured and easy to search. The average block fuel intensity of new aircraft decreased 41% from 1970 to 2019, and that is a economics boeing 757-200er Vip CompareD WiTH oTHer airCraFT Model First year produced Variable cost/hour Seats exec/max Range (nm) Normal cruise (kt) Max takeoff weight (lb) assumptions: boeing 757 is a 2005 model; the . This would make airlines far more attracted to buying the A220 over the Boeing 737 as the price of fuel goes up. Making statements based on opinion; back them up with references or personal experience. but herehttp://www.flywestwind.com/hangar/aircraft_files/foms/B752FOM.pdf The average traveler hardly stops to consider the technicalities involved in achieving flight. These figures correspond to overall . Whats the truth!? That same year, Cathay Pacific and Cathay Dragon consumed 4,571,000tonnes of fuel to transport 123,478million revenue passenger kilometers, or 37g/RPK, 25% better than in 1998: 4.63L/100km (50.8mpgUS). On the other side, the least efficient was British Airways at 27 pax-km/L (3.7L/100km[64mpgUS] per passenger), using fuel-inefficient Boeing 747-400s with a low density of 0.75 seat/m2 due to a high 25% premium seating, in spite of a high 82% load factor. You have everything except the diameter of the fuselage which is what I am looking for, Diameter of the fuselage: vertically 4.01 meter (158 inch); horizontally 3.76 meter (148 inch), both are exterior measurements.
