Some airports are placed in locations with high altitudes/elevation with high ambient temperatures around. In these kinds of airports, take-offs become difficult because the low air density negatively affects the lift generated by the wings or the rotors of the airplane. This also affects and hampers with the performance of the aircraft engines, jeopardizing the safety of the flight in the process. Therefore, unusually long runways in such areas are a suitable solution. With increased aircraft take-off run distance, the aircraft gets more energy for the climb to the sky.
Why do some airports have unusually long runways?
