API 5 defines which roles?

• A. Flight surgeon and flight physician: actively flying
• B. Staff officer above wing level
• C. Navigator assigned to trainer aircraft
• D. Rated officer in non-flying duties

Answer: (A)

API 5 identifies which medical personnel are considered part of the aircrew in an active flying capacity. It designates flight surgeon and flight physician as the roles that actively fly, meaning they operate in the flight environment and must stay current with in-flight medical readiness and care. This distinction matters because these officers must be prepared to provide medical support during missions just like other aircrew members.

The other options describe roles that are not designated as actively flying aircrew under API 5—staff officers not assigned to the flight line, a navigator on trainer aircraft, or a rated officer in non-flying duties—so they don’t fit the definition of active flying roles.
