Qantas operates under which Part?

• A. Part 121
• B. Part 135
• C. Part 91
• D. Part 145

Answer: (A)

Part 121 governs scheduled air carrier operations—the big, regularly scheduled flights that carry passengers and cargo on a fixed timetable. It sets the standards for certification, crew qualifications, flight operations, maintenance, dispatch, and recordkeeping for these carriers. A major international airline like Qantas operates extensive, scheduled service between cities worldwide, so its operations align with the requirements of Part 121.

By comparison, Part 135 covers on-demand or commuter operations with smaller aircraft, Part 91 handles non-commercial or general aviation rules with lighter requirements, and Part 145 relates to maintenance repair stations.
