What document, that provides information to the pilot, must be updated on an annual basis?

• A. Airport Facility Directory
• B. National Airspace Plan
• C. Air Traffic Services Guide
• D. Pilot Weather Almanac

Answer: (A)

Pilots rely on current, airport-specific information to plan and operate flights. The Airport Facility Directory is the resource that provides all the essential details for each airport—things like runway length and surface, available services, lighting hours, communications frequencies, and other operational notes. Because airport facilities can change (new services, different hours, updated lighting, runway work, etc.), this document is updated on a regular cycle to keep the data current, typically on an annual basis. That currency is why it’s the best choice here: it directly delivers the on-site information pilots need for planning and in-flight decisions.

The other options focus on different aspects: the National Airspace Plan describes how airspace is structured, the Air Traffic Services Guide covers ATC procedures and services, and the Pilot Weather Almanac provides weather-related information but not the comprehensive, airport-specific data used for daily operations.
