Which publication would a pilot consult for information on airports, communications, and NAVAIDs?

• A. Aeronautical Information Manual
• B. Chart Supplement U.S.
• C. NOTAMs
• D. Pilot's Handbook

Answer: (B)

Knowing where to find up-to-date information about airports, radio communications, and navigational aids is essential for safe flight planning and operations. The Chart Supplement U.S. is the official directory that compiles all of that in one place: it lists each airport’s facilities, communications frequencies, available services, runway details, lighting, and the presence of NAVAIDs. It’s updated on a regular cycle (every 56 days), so the data you rely on reflects current conditions and services.

The Aeronautical Information Manual provides broad guidance on navigation, weather sources, airspace rules, and safety practices. It’s a great reference for understanding how things work, but it isn’t the source you’d use for the latest, airport-specific data like frequencies and NAVAID information.

NOTAMs alert you to temporary changes or hazards, such as runway closures or frequency shifts, and these are important to check before flight—but they supplement the standard directory rather than replace it.

The Pilot’s Handbook is a training resource focused on flight fundamentals and piloting skills, not a current reference for airport data, frequencies, or navigational aids.
