What is the hold short distance from a runway when there is no hold short line?

When there is no designated hold short line marking on a taxiway, the standard hold short distance from the runway is 200 feet. This distance is established to ensure that aircraft maintain a safe separation from the runway environment, allowing for the safe operation of arriving and departing aircraft. The 200-foot buffer helps to mitigate the risk of runway incursions, which can occur if aircraft or vehicles inadvertently enter the runway area without clearance.

Maintaining this distance is critical, particularly in busy air traffic control environments, as it provides adequate response time for air traffic controllers and pilots to manage any potential conflicts. This is in accordance with aviation procedures and safety protocols, which prioritize the prevention of accidents by maintaining clear and defined spaces around operational runways.
