How do automatic weather observation systems support runway operations during severe weather?

• A. They continuously supply current weather data to alert operators and flight crews to hazards.
• B. They replace human weather observers.
• C. They provide data only hourly.
• D. They adjust runway lighting automatically.

Answer: (A)

Automatic weather observation systems provide continuous, real-time weather data that is vital for runway operations in severe weather. This constant stream of information about wind, visibility, precipitation, temperature, dew point, and altimeter settings lets operators and flight crews quickly detect hazards as conditions change. With up-to-the-minute data, ATC and airlines can issue timely alerts, adjust takeoff and landing plans, and implement appropriate procedures such as braking action assessments and low-visibility operations when needed. These systems feed automated reports and displays that support decision-making, rather than replacing human observers. They don’t generate hourly-only data, and they don’t directly control runway lighting, which is managed by the airport’s lighting control systems.
