What is indicated by the time of sunrise published by the United States National Weather Service?

The time of sunrise published by the United States National Weather Service refers specifically to the moment the sun is expected to rise at the airport. This information is crucial for various operational considerations at airports, including visibility for ramp agents and flight crews. Knowing the precise time of sunrise allows personnel to plan their activities accordingly, ensuring safety and efficiency in ground operations.

For instance, ramp agents may use the sunrise time to determine when lighting conditions are favorable for loading and unloading aircraft. Additionally, the rising sun can impact visibility in certain areas of the airfield, making it essential for operational planning and safety assessments. This piece of information does not directly correlate with airline operations, flight restrictions, or mandatory inspections, which are governed by separate regulations and schedules. Instead, it serves as a reliable reference for understanding daylight availability at the airport.
