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.
The basic purpose of a flight planning system is to calculate how much trip fuel is needed in the air navigation process by an aircraft when flying from an origin airport to a destination airport. Aircraft must also carry some reserve fuel to allow for unforeseen circumstances, such as an inaccurate weather forecast, or air traffic control ...
Holding over the destination or alternate airports is a required part of some flight plans. Holding (circling in a pattern designated by the airport control tower) may be necessary if unexpected weather or congestion occurs at the airport. If the flight plan calls for hold planning, the additional fuel and hold time should appear on the flight ...
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...
The rule affected only those aircraft operating under IFR when in level flight above 3,000 ft above mean sea level, or above the appropriate transition altitude, whichever is the higher, and when below FL195 (19,500 ft above the 1013.2 hPa datum in the UK, or with the altimeter set according to the system published by the competent authority in ...
The most common standard flight length measurement is by great-circle distance, a formula that calculates the shortest distance across the curvature of the earth for two airports' ARPs. [5] It is the only measurement that is constant on a given city-pair route and unaffected by operational variances. [ 6 ]

Between the surface and an altitude of 29,000 feet (8,800 m), no aircraft should come closer vertically than 300 metres, unless some form of horizontal separation is provided (Note: for countries that measure altitude in feet, a 1,000 feet minimum is observed rather than the 984.252 feet found in 300 meters).
