What does the (A)* symbolize in the data for an airport on En Route Low Altitude Charts?

• A. Full-time control tower
• B. Ground radar control
• C. ATIS availability
• D. Air traffic advisory service

Answer: (C)

The symbol (A)* on En Route Low Altitude Charts indicates the availability of the Automatic Terminal Information Service (ATIS) at an airport. ATIS is a continuous broadcast of recorded information regarding weather conditions, runways in use, and other critical information relevant to pilots as they approach and land at an airport. The presence of this symbol informs pilots that they can access this vital information when preparing to arrive at the airport, aiding in their situational awareness and decision-making processes in the terminal airspace. This distinguishes it from other symbols which represent different operational aspects, such as control tower presence or radar services, thus specifically focusing on the communication of pre-recorded information that enhances safety and efficiency in aviation operations.
