What does 14 CFR Part 63 focus on?

• A. Certification: Flight Crewmembers other than Pilots
• B. Certification: Pilots, Flight Instructors, and Ground Instructors
• C. Medical Standards and Certification
• D. Operating Certain Small Aircraft Without a Medical Certificate

Answer: (A)

Part 63 is the regulation that governs certification of flight crewmembers other than pilots. It sets who needs a certificate in these roles—such as flight engineers, flight navigators, and certain flight attendants—and describes the process to obtain it, including the required knowledge and practical tests that demonstrate their qualifications for those duties. This is distinct from the medical standards part, which is a different regulation, and from the part that covers pilots, flight instructors, and ground instructors. It also isn’t about operating aircraft without a medical certificate, which relates to other rules.
