  2. 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 ...

  3. Travelling salesman problem - Wikipedia

    en.wikipedia.org/wiki/Travelling_salesman_problem

    When the cities are viewed as points in the plane, many natural distance functions are metrics, and so many natural instances of TSP satisfy this constraint. The following are some examples of metric TSPs for various metrics. In the Euclidean TSP (see below), the distance between two cities is the Euclidean distance between the corresponding ...

  4. Great-circle distance - Wikipedia

    en.wikipedia.org/wiki/Great-circle_distance

    Two antipodal points, u and v are also shown. The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them. This arc is the shortest path between the two points on the surface of the sphere. (By comparison, the shortest path passing ...

    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]

    Δ λ = λ 2 − λ 1 {\displaystyle \Delta \lambda =\lambda _ {2}-\lambda _ {1}} . Finally, the haversine function hav (θ), applied above to both the central angle θ and the differences in latitude and longitude, is. The haversine function computes half a versine of the angle θ, or the squares of half chord of the angle on a unit circle ...

    The airline uses the Airbus A350-900ULR (“ultra-long range”) aircraft on the route, which has an extended range of up to 9,700 nautical miles. 2. Auckland to Doha - Qatar Airways

  8. Geographical distance - Wikipedia

    en.wikipedia.org/wiki/Geographical_distance

    Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...

  9. Great-circle navigation - Wikipedia

    en.wikipedia.org/wiki/Great-circle_navigation

    Great-circle navigation. Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe.
