What is the width of taxiways?

The correct choice indicates that the standard width of taxiways is 75 feet, accompanied by a total shoulder width of 50 feet. This specification aligns with the design and safety standards set out in aviation regulations, which aim to ensure that taxiways are adequately proportioned to accommodate the operation of various aircraft sizes safely. The combination of the taxiway width and shoulder width provides not only adequate clearance for aircraft maneuvering but also establishes safe zones for ground handling activities. The shoulders help reduce the risk of aircraft overrunning the paved surfaces, providing an additional safety margin. Understanding these dimensions is crucial for airport designers, air traffic controllers, and maintenance teams to ensure smooth operations and safe maneuvering on the ground.
