Who is authorized to start, run up, and taxi aircraft?

• A. Rated Pilots and Qualified Technicians
• B. Flight Attendants
• C. Ground Handling Personnel
• D. Passengers

Answer: (A)

Starting and moving an aircraft on the ground are controlled operations that require formal training and certification. Only people who are properly authorized can perform these tasks to ensure safety and adherence to procedures. A pilot with an active rating has the authority and training to start engines, conduct engine run‑ups to verify performance and systems, and taxi the aircraft following standard ground rules. Qualified maintenance technicians, when working under approved procedures and the aircraft being properly isolated, can also perform engine run‑ups as part of maintenance checks. Flight attendants, ground handling personnel, and passengers do not have this authorization, because starting engines or taxiing without the proper training and clearance could lead to serious safety risks.
