What is the distance requirement from the edge for VFR hold line markings?

The distance requirement from the edge for VFR (Visual Flight Rules) hold line markings is set at a minimum of 100 feet. This regulation is crucial for ensuring safety on the airfield by providing adequate separation between the runway and the position of aircraft or vehicles. The VFR hold line markings indicate where an aircraft is required to stop when approaching a runway for takeoff or landing under visual flight conditions.

By maintaining this 100-foot distance, it allows for safe clearance from the active runway, minimizing the risk of runway incursions and enhancing the overall flow of air traffic. Additionally, it provides space for both visual confirmation by pilots and the necessary reaction time for any commands or signals from air traffic control. Following this distance requirement significantly contributes to maintaining an orderly and safe airfield environment.
