Flight length

(Redirected from Long-haul flights)

In aviation, the flight length refers to the distance of a flight.[citation needed] Commercial flights are often categorized into long-, medium- or short-haul by commercial airlines based on flight length, although there is no international standard definition and many airlines use air time or geographic boundaries instead. Route category lengths tend to define short-haul routes as being shorter than 600–800 nmi (1,100–1,500 km), long-haul as being longer than 2,200–2,600 nmi (4,100–4,800 km), and medium-haul as being in-between.[citation needed]

The related term flight duration is defined as to the amount of time a single flight (segment) is scheduled to take from pushing back at the departure gate to arriving at its destination gate.[1] It is formally defined by ICAO (International Civil Aviation Organization) as "The total time from the moment an aeroplane first moves for the purpose of taking off until the moment it finally comes to rest at the end of the flight" also referred to colloquially as "chocks to chocks" time.[2]

Flight duration is formally measured in hours & minutes as it is irrespective of geographic distance traveled. A route's flight duration can be affected by many things such as anticipated routings, weather, traffic, or taxiing times.[3] Scheduled durations for the same route and airline can also vary on what aircraft is used.

A flight's duration can also be described using the aviation term of "Flight Haul Type",[4] such as "Short Haul" or "Long Haul" that have multiple different definitions depending on originating sources. See the below table for some more prominent examples:

Flight haul type definitions
Short-haul Medium-haul Long-haul Ultra-long-haul
ICAO[5][6] < 8 hours 8–16 hours > 16 hours
IATA[7][8][4][9] < 3 hours 3–6 hours 6–16 hours > 16 hours
CAPA (aviation industry news publisher)[10] < 6 hours 6–16 hours > 16 hours

Route category definitionsEdit

 
Lufthansa considers the Embraer E-190 a short-haul airliner.
 
Lufthansa considers the Airbus A320 family a medium-haul airliner.
 
Lufthansa defines the Boeing 747-8 as a long-haul airliner.

Flight Haul Type terms are often used to describe flight length by aviation entities such as airlines, airports, and government authorities. The definitions vary as they are subjective for that entities' purposes and provide a specific message to their customers how they view a flight as being long or short. Some examples include:

Asia & AustraliaEdit

  • Hong Kong International Airport considers destinations in North and South Americas, Europe, the Middle East, Africa, Southwest Pacific and the Indian Subcontinent long-haul and all others are short-haul.[11]
  • Japan Air Lines defines routes to Europe and North America as long-haul and all other flights as short-haul.[12]
  • Qatar Airways defines all flights from Qatar to the Americas, Australia, and New Zealand as Ultra-long-haul, and all other flights as medium or long-haul.[13]
  • Virgin Australia defines domestic flights as within Australia, short-haul as those to South East Asia/Pacific and long-haul as those to Abu Dhabi or Los Angeles.[14]

EuropeEdit

  • The European Union defines any passenger flight between city pairs separated by a great circle distance less than 1,500km to be short-haul, between 1,500 and 3,500km as medium-haul, and all flights greater than 3,500km to be long-haul routes.[15]
  • Eurocontrol defines "very short-haul" flights as being less than 500km, short-haul flights being between 500 to 1,500 km, medium-haul flights being between 1,500 and 4,000 km (930 and 2,490 mi; 810 and 2,160 nmi), and long-haul flights as longer than that.[16]
  • The Association of European Airlines defined Long-haul as flights to Americas, sub-Saharan Africa, Asia, Australasia and medium-haul as flights to North Africa and Middle East.[17]
  • The now defunct airline Air Berlin defined short- and medium-haul as flights to Europe/North Africa and long-haul as those to the rest of the world.[18]
  • Air France defines short-haul as domestic, medium-haul as within Europe/North Africa and long haul as the rest of the world.[19]

North AmericaEdit

  • American Airlines defines short-/medium-haul flights as being less than 3,000 mi (2,600 nmi; 4,800 km) and long-haul as either being more than 3,000 mi (2,600 nmi; 4,800 km) or being the New York–Los Angeles and New York–San Francisco routes.[20]
  • United Airlines defines short-haul flights as being less than 700 mi (610 nmi; 1,100 km)[21] and long-haul flights as being greater than 3,000 mi (2,600 nmi; 4,800 km).[22]

Aircraft category definitionsEdit

Flight Haul Type terms are sometimes used when referring to commercial aircraft. Some commercial carriers choose to refer to their aircraft using flight haul type terms, for example:


While they are capable of flying further, long-haul capable wide-bodies are often used on shorter trips. In 2017 - 40% of A350 routes were shorter than 2,000 nmi (2,300 mi; 3,700 km), 50% of A380 flights fell within 2,000–4,000 nmi (2,300–4,600 mi; 3,700–7,400 km), 70% of 777-200ER routes were shorter than 4,000 nmi (4,600 mi; 7,400 km), 80% of 787-9s routes were shorter than 5,000 nmi (5,800 mi; 9,300 km), 70% of 777-200LRs flights were shorter than 6,000 nmi (6,900 mi; 11,000 km).[26]

Superlative flightsEdit

Shortest commercial flightEdit

The Westray to Papa Westray flight in Orkney, operated by Loganair, is the shortest commercial flight in the world over 2.8 km (1.7 mi) in two minutes scheduled flight time including taxiing.

Longest commercial flightEdit

The world's longest ever commercial flight was Air Tahiti Nui Flight TN64[27] in early 2020. Due to the COVID-19 pandemic and the impossibility of transit in the USA through Los Angeles International Airport, Air Tahiti Nui scheduled and operated in March and April 2020 Flight TN64 as a non-stop flight between Papeete and Paris Charles de Gaulle, using a Boeing 787-9 and covering 15,715 km (9,765 mi; 8,485 nmi).[28][29] in a scheduled time of 16 hours and 20 minutes.[30][31] As of 2023 continues to hold the record for the longest ever scheduled commercial nonstop flight (by great circle distance) as well as the world's longest domestic flight.

From November 9, 2020, Singapore Airlines SQ 23/24 is the world's longest active commercial flight between Singapore and JFK Airport New York City, USA, covering 15,349 km (9,537 mi; 8,288 nmi) in around 18 hours and 40 minutes, operated by an Airbus A350-900ULR.[32]

DistinctionsEdit

Absolute distance versus flight lengthEdit

 
Airline routes between San Francisco and Tokyo following the most direct great circle (top) westward, and following a longer-distance jet stream route (bottom) when heading eastward

The absolute distance between two points is the great-circle distance, which is always the shortest geographical route. In the example (right), the aircraft travelling westward from North America to Japan is following a great-circle route extending northward towards the Arctic region. The apparent curve of the route is a result of distortion when plotted onto a conventional map projection and makes the route appear to be longer than it really is. Stretching a string between North America and Japan on a globe will demonstrate why this really is the shortest route despite appearances.

The actual flight length is the length of the track flown across the ground in practice, which is usually longer than the ideal great-circle and is influenced by a number of factors such as the need to avoid bad weather, wind direction and speed, fuel economy, navigational restrictions and other requirements. In the example, easterly flights from Japan to North America are shown taking a longer, more southerly, route than the shorter great-circle; this is to take advantage of the favourable jet stream, a fast, high-altitude tail-wind, that assists the aircraft along its ground track saving more time and fuel than the geographically shortest route.

Flight Length versus Flight Duration exampleEdit

Even with the same length, a route's flight duration can be affected by anticipated routings, seasonal weather, traffic, taxiing time, or equipment capabilities as seen in this example:

On the Luxembourg to Bucharest route operated by LuxAir, the scheduled flight length remains constant while the flight duration varies depending on aircraft used:

  • On Thursday mornings, LuxAir operates a DHC-8 Turboprop with a scheduled duration of approximately 3 hours.[33][34]
  • While on Saturday mornings, LuxAir operates a Embraer 190 Jet Airliner, which reduces the scheduled duration of the flight down to approximately 2 hours 20 minutes.[33][35]
