Ceiling/sky condition, visibility, and obstructions to vision may be omitted if the ceiling is above ________ feet and the visibility is more than ________ miles.

• A. 5,000; 5
• B. 3,000; 3
• C. 6,000; 6
• D. 4,000; 4

Answer: (A)

When weather is very good, some elements of the observation can be omitted. If the ceiling is above 5,000 feet and the visibility is more than 5 miles, the report may omit the ceiling/sky condition, visibility, and obstructions to vision. This reflects that under these favorable conditions, pilots and controllers already have a clear sense of the weather, and detailing those elements adds little value. So the threshold for omitting these reports is a ceiling above 5,000 feet with visibility over 5 miles.
