When ceiling is above 5,000 feet and visibility is more than 5 miles, which information may be omitted?

• A. Ceiling/sky condition, visibility, and obstructions to vision
• B. Wind speed and direction
• C. Temperature only
• D. All weather data

Answer: (A)

When weather is well above the minimums for visual flight rules, certain visual weather details don’t constrain safety and can be left out from a quick briefing. If the ceiling is above 5,000 feet and visibility exceeds 5 miles, you’re clearly in favorable VFR conditions, so noting the exact sky condition, visibility nuances, or any obstructions to vision doesn’t affect the immediate planning or decision-making. What remains important are data that can influence performance and routing, like wind and temperature, which can affect aircraft performance, fuel planning, and navigation.

Wind speed and direction still matter for planning a safe and efficient flight, and temperature is not something you’d omit by itself. Saying all weather data would be omitted is too broad, since you do need some information for performance calculations and obstacle avoidance.
