Primary work-rest authority rests with the aircraft commander for which individuals?

• A. FCC
• B. MRT Chief
• C. ART
• D. Expeditor

Answer: (A)

Fatigue management in flight operations hinges on who is actively responsible for the aircraft during the flight. The aircraft commander is in charge of the aircraft and has the final say over work-rest decisions for the people directly involved in operating the aircraft—the flight crew (FCC). Since these individuals are part of the flight team and their safety depends on whether they’re rested, the primary authority to regulate their work-rest rests with the aircraft commander.

Roles like MRT Chief, ART, or Expeditor operate in support or ground roles and are not directly operating the aircraft, so their rest and duty decisions are handled through other supervision channels, not the aircraft commander.
