Answer :
Final answer:
The purpose of the yellow demarcation bar marking is to delineate the runway with a displaced threshold from areas not intended for landing such as a blast pad, stopway, or taxiway. It is critical for safety during landing and takeoff operations. The correct answer to the question is option C: Delineates runway with a displaced threshold from a blast pad, stopway or taxiway that precedes the runway.
Explanation:
The purpose of the yellow demarcation bar marking is often misunderstood, but it serves a very specific and crucial role in airport operations. The correct answer to the question is option C: Delineates runway with a displaced threshold from a blast pad, stopway or taxiway that precedes the runway. This means that the yellow demarcation bar is used to mark a clear distinction between the beginning of the runway that is available for landing and other areas that are not intended for landing, such as a blast pad, stopway, or taxiway. This is critical for pilots during landing and takeoff operations to ensure the safety and efficiency of these maneuvers.
Understanding the purpose of different runway and taxiway markings is essential for anyone involved in aviation, including pilots, air traffic controllers, and airport personnel. These markings provide important visual cues that help maintain safe distances, guide aircraft during ground movements, and ensure that runways are used correctly.
