Answer :
Final answer:
A visual runway, used for VFR operations, is marked with white centerline and edge markings, as well as a white runway threshold. Yellow is not typically used for runway edge markings; it is reserved for taxiway edge markings.
Explanation:
A visual runway is used for visual flight rules (VFR) operations. Its markings are designed to provide positional awareness to pilots during takeoff, landing, and taxiing under visual conditions. The specific markings for a visual runway include:
- White runway centerline: This is a continuous or dashed line that runs down the center of the runway to assist pilots with alignment during takeoff and landing.
- White runway threshold: Markings at the beginning of the runway that indicate the start of the runway available for landing.
- White runway edge markings: These are continuous lines that denote the edges of the runway.
- White or yellow taxiway markings: These indicate areas for aircraft to taxi but are not intended for takeoff or landing.
The markings for a visual runway ensure that pilots can clearly see and orient themselves on the runway's layout, especially during daylight and favorable weather conditions when pilots operate predominantly under VFR.
