Airports with long runways are required for larger aircraft to accelerate to an acceptable speed to produce lift and become airborne. The larger and heavier the plane, the more speed and runway length are needed. In addition, longer runways are beneficial in unfavourable weather conditions, providing extra stopping distance in snowy conditions, for example. They are also useful in hotter temperatures and high altitudes. The longest runway in the world is thought to be at Qamdo Bamda Airport (BPX) in Tibet, which has a runway of 5,500 metres. However, some reports suggest this runway is no longer in use and has been replaced by a 4,500-metre runway.

What You'll Learn
The world's longest runway is in Tibet
The world's longest runway is located in the Tibet Autonomous Region of China, at the Rikaze Peace Airport (RKZ). The runway is 16,000 feet long, or 5,000 meters, and sits at an elevation of 12,408 feet above sea level. The airport is located 26.7 miles from Shigatse, Tibet's second-largest city, in Jiangdang Township.
Rikaze Peace Airport first opened as a military facility in 1973 and became a dual-use military and civilian airport in 2010 following a 532 million yuan expansion. The Airbus A319 is one of the few aircraft certified to operate at such high altitudes, and the thin air and low oxygen levels pose challenges for aircraft operation. The climate at the airport is dry and monsoon-influenced, with hot and humid summers and cold, dry, and windy winters. The area is also subject to sandstorms in the spring, blowing across the Mongolian steppe from the Gobi Desert.
High-altitude airports like Rikaze Peace Airport have longer runways than those at sea level due to thinner air. This, along with unpredictable and rapidly changing weather, forces pilots to carefully calculate takeoff and landing distances, as well as the plane's rate of climb. The Airbus A319 aircraft used at the airport are equipped with special features for high-elevation operations.
In addition to its impressive length, the runway at Rikaze Peace Airport serves as a testing ground for the People's Republic of China military's high-altitude long-endurance Guizhou WZ-7 Soaring Dragon unmanned aerial reconnaissance drones. The airport is not the world's highest, but it shares the title of having the world's longest runway with Ulyanovsk Vostochny Airport (ULY) in Russia.

Two airports share the second-longest runway
The world's longest runway can be found at either China's Shigatse Peace Airport or Russia's Ulyanovsk Vostochny Airport, with both runways stretching 5,000 metres. However, some sources claim that the Qamdo Bamda Airport in Tibet previously held the title with its 5,500-metre runway, which has since been replaced by a 4,500-metre runway.
Two airports share the title of having the second-longest runway in the world. Moscow's Zhukovsky International Airport (ZIA) in Russia and the now-replaced runway at Qamdo Bamda Airport in Tibet both feature runways with a length of 5,400 metres. Zhukovsky International Airport, located southeast of central Moscow in the city of Zhukovsky, serves a handful of domestic, international, and charter flights. It is Moscow's fourth international airport and can accommodate a fully loaded Airbus A380.
Qamdo Bamda Airport, on the other hand, is situated in Tibet at an elevation of 4,334 metres. The airport's long runway was necessary due to the high altitude, as aircraft require longer runways at higher elevations. The surrounding terrain, including mountains and plateaus, also contributes to the need for a longer runway for takeoff and landing.
While the two airports share the distinction of having the second-longest runway, they differ in terms of their location, elevation, and the types of aircraft they serve. Zhukovsky International Airport is located in a relatively flat region, while Qamdo Bamda Airport is situated in a high-altitude area with challenging terrain. Additionally, Zhukovsky International Airport caters to a range of commercial and charter flights, whereas Qamdo Bamda Airport likely accommodates smaller aircraft due to its remote location.

Madrid-Torrejón Airport is fourth
When it comes to aircraft operations, longer runways are beneficial as they allow aircraft to accelerate to the speed required for takeoff or landing. Several factors influence the length of runway required, including the size and weight of the plane, weather conditions, and altitude.
Qamdo Bamda Airport (BPX) in Tibet has the world's longest runway, stretching 5,500 meters. However, some reports indicate that this runway is no longer in use and has been replaced by a 4,500-meter runway. The second-longest runway in the world is at Moscow's Zhukovsky International Airport (ZIA), measuring 5,400 meters.
China's Shigatse Peace Airport and Russia's Ulyanovsk Vostochny Airport share the title of having the longest runways in the world at 5,000 meters. Other airports with notably long runways include Denver International Airport in the United States, with a 4,877-meter runway, and Hamad International Airport in Qatar, with a 4,850-meter runway.
Among all these impressive runways, Madrid-Torrejón Airport stands out as the fourth-longest runway at a commercial airport. Situated just 15 miles northeast of Madrid, it serves both the Spanish Ministry of Defence and the Ministry of Public Works.

Denver International Airport is the fourth-longest commercial runway
Denver International Airport, often referred to as DIA by locals, is an international airport in the Western United States. It primarily serves metropolitan Denver, Colorado, as well as the greater Front Range Urban Corridor. With a runway measuring 4,877 meters, it is the fourth-longest commercial runway in the world.
Denver International Airport is the largest airport in the Western Hemisphere by land area and the second-largest on Earth, behind King Fahd International Airport. The airport covers a total area of 33,531 acres, or 52.4 square miles. Its runway 16R/34L, with a length of 16,000 feet, is the longest public-use runway in North America and the seventh-longest on Earth. This runway is so long that it is over three miles in length, or the equivalent of 53 football fields.
Denver is known as the "Mile High City" because it sits at an elevation of one mile, or 5,300 feet, above sea level. The air pressure in Denver is around 85% of sea level, which affects how planes take off and land. At this altitude, airplanes need to fly faster to generate the same amount of lift, but their engines produce less power, so the plane accelerates more slowly. As a result, planes need more distance to take off and land, which is why the runway at Denver International Airport is so long.
Denver International Airport has a total of six runways, four of which are oriented north-south due to the "average wind" direction in the region. The airport has flights to over 215 destinations, making it one of the few US airports to exceed 200 destinations. It is also one of the busiest airports in the United States due to its ideal midcontinent location for an airline hub.
