What is the lateral clearance distance from the taxiway centerline to parked or moving vehicles?

The correct distance for lateral clearance from the taxiway centerline to parked or moving vehicles is 200 feet. This standard is established to ensure safety in the maneuvering areas of an airfield. A separation of 200 feet helps to prevent potential collisions and incidents, as it provides ample space for aircraft operating on the taxiway to pass by parked or moving vehicles without risk of encroachment.

Maintaining this lateral clearance is crucial for the safe operation of aircraft, especially in busy airfield environments where multiple taxiing operations may occur simultaneously. This distance effectively accommodates the wingspan of various aircraft, thereby enhancing safety margins during ground movements.
