What are crewmembers on flight orders flying on AMC aircraft and not performing primary duties called?

• A. Relief pilots
• B. Guest observers
• C. Additional crew members
• D. Ground crew

Answer: (C)

On AMC flights, when someone is carried on the flight orders but isn’t assigned to perform the aircraft’s primary mission duties, they’re designated as additional crew members. They accompany the mission to provide support, safety, or training needs without flying the aircraft or taking on core operational tasks. Relief pilots are actively flying to cover duty time, so they perform primary flight duties. Guest observers are there to observe or learn, not to perform crew tasks. Ground crew stay on the ground for maintenance and aren’t on the flight.
