An aviation biofuel (also known as bio-jet fuel[1] or bio-aviation fuel (BAF) [2]) is a biofuel used to power aircraft and is a sustainable aviation fuel (SAF). The International Air Transport Association (IATA) considers it a key element in reducing the environmental impact of aviation. [3] Aviation biofuel is used to decarbonize medium and ...
A short-range aircraft (< 2,000 km, 1,100 nmi) with hybrid Fuel cell/Turbines could reduce climate impact by 70-80% for a 20-30% additional cost, a medium-range airliner with H 2 turbines could have a 50-60% reduced climate impact for a 30-40% overcost, and a long-range aircraft (> 7,000 km, 3,800 nmi) also with H 2 turbines could reduce ...
The agency's goal was to reduce the number of people around airports exposed to a day-night average aircraft sound level of 65 decibels to less than 300,000 by 2018. [184] One way the agency planned to achieve that goal was by adopting a new noise standard for certain newly certificated subsonic jet airplanes and subsonic transport category ...
While manufacturers are making long-term investments in hydrogen-propulsion systems and electric airplanes, airlines have to settle for purchasing aircrafts that use SAF to reduce carbon emissions ...
The history of aviation spans over two millennia, from the earliest innovations like kites and daring attempts at tower jumping to supersonic and hypersonic flight in powered, heavier-than-air jet aircraft. Kite flying in China, dating back several hundred years BC, is considered the earliest example of man-made flight.
An airplane (North American English) or aeroplane (British English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of ...
Aeronautics is the science or art involved with the study, design, and manufacturing of air flight -capable machines, and the techniques of operating aircraft and rockets within the atmosphere. While the term originally referred solely to operating the aircraft, it has since been expanded to include technology, business, and other aspects ...
The -150 involves the conversion of Group 1 and Group 2 L-1011-1 aircraft to an MTOW of 470,000 pounds (210,000 kg), an increase of 40,000 pounds (18,000 kg), about 10%, from the L-1011-1, giving the aircraft a slightly better range than the -50, but without the additional center-section fuel tank, less than the L-1011-100 aircraft.
