You are number one and holding short of the runway. What pavement markings do you see?

When you are number one and holding short of the runway, the most relevant pavement markings to observe are the two solid yellow lines close to the aircraft. These solid yellow lines indicate the location where aircraft are required to stop before entering the runway. They serve as a clear visual cue to pilots that they are at the point where they must yield to any traffic on the runway.

The solid yellow lines delineate the boundary between the taxiway and the runway, emphasizing the importance of maintaining awareness of air traffic rules and ensuring safety by preventing incursions onto the runway without clearance. These markings are crucial for promoting safe operations at an airport, particularly in busy environments where precise navigation and adherence to air traffic control instructions are vital.

In contrast, the other choices represent different types of markings that are not applicable to the scenario described. For example, dashed white lines typically indicate a boundary for taxiway merging or merging lanes, which does not apply when holding short of the runway. Similarly, the solid red line is commonly used in areas to signify that no entry is allowed, but this is not the case when you are prepared for takeoff. Broken red lines are also used in various situations but do not pertain specifically to the holding position before a runway. Therefore, the
