What is the function of ATIS in aviation radiocommunications?

• A. ATIS provides a continuous automated broadcast of essential airport information.
• B. ATIS is a manual information service by ATC.
• C. ATIS provides only weather data.
• D. ATIS is for pilot medical information.

Answer: (A)

ATIS is an Automatic Terminal Information Service that provides a continuous automated broadcast of essential airport information. This typically includes the latest weather observations (wind, visibility, sky condition, temperature and dew point, altimeter), active runway and lighting information, available approaches, and any relevant notices such as NOTAMs. The information is updated regularly or whenever conditions change, and each broadcast is identified by a unique letter so pilots can reference the current information when contacting ATC. This system reduces the need for live repetitive transmissions from controllers and helps pilots prepare for taxi, approach, or takeoff with the most current data.
