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 ...
Distance measuring equipment. In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ...
The longest ever scheduled passenger flight was Air Tahiti Nui 's flight TN64 using a Boeing 787-9, flying non-stop from FaaŹ»a 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 ]
For such flights, the critical fiscal factor is the quantity of fuel burnt per seat-nautical mile. [9] For these reasons, the world's longest commercial flights were cancelled c. 2013 . 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 (16,600 km ...
A primary flight display with the indicated airspeed (IAS) displayed in the form of a vertical "tape" on the left. Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system [1] and displayed by the airspeed indicator (ASI). [2] This is the pilots' primary airspeed reference.
The term , where is the speed, and is the fuel consumption rate, is called the specific range (= range per unit mass of fuel; S.I. units: m/kg). The specific range can now be determined as though the airplane is in quasi-steady-state flight. Here, a difference between jet and propeller-driven aircraft has to be noticed.
Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.
In the air, the flight computer can be used to calculate ground speed, estimated fuel burn and updated estimated time of arrival. The back is designed for wind correction calculations, i.e., determining how much the wind is affecting one's speed and course. One of the most useful parts of the E6B, is the technique of finding distance over time.
