What level of medical certificate must crewmembers maintain?

• A. Third Class
• B. Second Class
• C. First Class
• D. No medical requirement

Answer: (C)

Medical certificates are tied to the level of medical fitness required for the operation. Crewmembers flying revenue or passenger-carrying missions under Part 135 are held to the higher, air-carrier-like standard, so a first-class medical certificate is required. This certifies the strictest medical qualifications and supports the demanding schedules and safety expectations of these operations. A third-class certificate is the minimum for basic private flying, a second-class covers many commercial operations but not the most stringent cases, and there is no medical requirement in a non-revenue, non-operational scenario.
