Airport layout of Kuala Lumpur Airport, a typical airport with triple parallel landing capabilities
Triple takeoff/landing capabilities are a necessity for many large airports as it allows many aircraft to arrive and depart in a short amount of time. Each country sets its own standards for the separation between runways required for parallel approaches. In the United States, the Federal Aviation Administration dictates that airports must have at least 3,000 feet (910 m) between runways,[1] though it can grant special permission to conduct parallel approaches with less separation if deemed necessary.
Airports with triple parallel landing capabilities
However, due to terrain constraints, triple parallel approaches are currently not authorized, only double parallel approaches or triple dependent approaches are approved for the 3 runways.
Though runway 18/36 is not magnetically aligned with the other parallel runways, existing approaches permit triple parallel operations with small aircraft.
