  2. Fuel economy in aircraft - Wikipedia

    en.wikipedia.org/wiki/Fuel_economy_in_aircraft

    Fuel economy in aircraft. Between 1950 and 2018, efficiency per passenger grew from 0.4 to 8.2 RPK per kg of CO₂. [1] The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel consumption ...

  3. Flight planning - Wikipedia

    en.wikipedia.org/wiki/Flight_planning

    A Tarom Boeing 737-300 and United Airlines Boeing 777-200 taxiing to depart London Heathrow Airport. Flight planning is the process of producing a flight plan to describe a proposed aircraft flight. It involves two safety-critical aspects: fuel calculation, to ensure that the aircraft can safely reach the destination, and compliance with air ...

  4. Flight length - Wikipedia

    en.wikipedia.org/wiki/Flight_length

    Flight length. In aviation, the flight length or flight distance refers to the distance of a flight. Aircraft do not necessarily follow the great-circle distance, but may opt for a longer route due to weather, traffic, to utilise a jet stream, or to refuel. Commercial flights are often categorized into long-, medium- or short-haul by commercial ...

  5. Thrust-specific fuel consumption - Wikipedia

    en.wikipedia.org/wiki/Thrust-specific_fuel...

    Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit ...

    en.wikipedia.org/wiki/Boeing_787_Dreamliner

    The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft ...

  7. Range (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Range_(aeronautics)

    The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1] Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions.

  8. Center of gravity of an aircraft - Wikipedia

    en.wikipedia.org/wiki/Center_of_gravity_of_an...

    Center-of-Gravity Limits. Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during flight. The CG limits are indicated in the airplane flight manual. The area between the limits is called the CG range of the aircraft.

  9. Longest flights - Wikipedia

    en.wikipedia.org/wiki/Longest_flights

    The longest ever scheduled passenger flight was Air Tahiti Nui 's flight TN64 using a Boeing 787-9, flying non-stop from Faaʻa International Airport in Papeete, Tahiti to Paris–CDG, [22] a distance of 15,715 kilometres (9,765 mi; 8,485 nmi) in a scheduled duration of 16 hours, 20 minutes. [23]
