AC 90-48 addresses which topic?

• A. Pilots' Role in Collision Avoidance
• B. Aeronautical Decision Making
• C. Advisory Circular
• D. Airworthiness Certification of Aircraft

Answer: (A)

AC 90-48 covers the Pilots' Role in Collision Avoidance. This FAA advisory circular provides guidance on how pilots should perform see-and-avoid to maintain separation from other aircraft, emphasizing active scanning, situational awareness, and clear decisionmaking to prevent midair conflicts. It reinforces that while ATC can help with traffic information, the primary responsibility for collision avoidance lies with the pilot. This topic is distinct from Aeronautical Decision Making, which is addressed in other ADM materials; from the general idea of what an Advisory Circular is (ACs are guidance documents, not subjects themselves); and from Airworthiness Certification of Aircraft, which deals with certification processes.
