Specific values of weather information may be transmitted to the pilot if the information is obtained from whom?

• A. A properly certificated observer
• B. Another pilot
• C. Air Traffic Manager
• D. Official news reports

Answer: (A)

Weather information with specific measured values must come from an authorized source that conducts standardized observations. A properly certificated observer is trained to observe and record key weather data—wind speed and direction, visibility, ceiling, temperature, dew point, and altimeter—using standardized methods. Their reports are the official basis for real-time values used by pilots, such as METARs and related weather data. Other sources don’t provide officially certified, real-time observations in the required standardized format: another pilot may share impressions, but not the formal values; the Air Traffic Manager isn’t the designated meteorological observation source for flight purposes; and official news reports aren’t timely or standardized for in-flight use.
