Answer :
Final answer:
Parallel runways are runways at an airport that are parallel to each other, allowing for efficient handling of aircraft traffic without the risk of on-ground collisions. Therefore the correct answer is d).
Explanation:
Runways that are designed this way allow for more efficient handling of aircraft traffic, permitting simultaneous landings or takeoffs. This configuration is especially beneficial at busy airports where airspace management is critical for safety and efficiency. Unlike intersecting runways or perpendicular runways, parallel runways do not intersect with each other, reducing the risk of on-ground collisions.
Parallel runways are two or more runways at an airport that are aligned in roughly the same direction and separated by a certain distance, allowing for simultaneous takeoffs and landings of multiple aircraft. These runways are typically used to increase the capacity and efficiency of airport operations, especially at busy airports with high air traffic volumes.
Having multiple parallel runways provides redundancy and resilience to airport operations by offering alternative landing and takeoff options in the event of runway closures due to maintenance, emergencies, or adverse weather conditions. This redundancy helps minimize disruptions and maintain continuity of airport services.
