When weather information changes, what should you do with existing clearances?

• A. Ignore weather changes and keep all clearances as issued.
• B. Only update weather information if pilots request it.
• C. Close all traffic until weather stabilizes.
• D. Adjust clearances as needed to reflect the weather.

Answer: (D)

Weather updates can change aircraft separation needs and how routes and altitudes are managed. When weather information changes, you adjust existing clearances as needed to reflect the new conditions. This keeps routing, altitudes, speeds, and holds appropriate for safety and efficiency in the updated weather picture. For example, if visibility decreases or wind shifts, you might reroute aircraft, assign different altitudes to maintain minimum separation, or adjust speeds to preserve spacing. The aim is to maintain safe, orderly, and efficient operations, rather than ignoring changes, waiting for pilots to request updates, or stopping traffic unless there’s an immediate safety reason.
