Who designates engine run-up areas in accordance with airport procedures?

• A. Ground crew supervisor
• B. Air traffic controller
• C. Commanding officer
• D. Flight engineer

Answer: (C)

Designating where engine run-ups occur is about ensuring a safe, compliant operating environment that follows airport procedures. In military flight operations, the person with overall authority for aircraft operations and safety—the commanding officer—establishes and enforces the procedures, including where engine run-ups can be performed. This ensures the chosen area meets airport requirements, noise and safety considerations, and provides proper clearances for emergency access and personnel. The ground crew supervisor handles execution on the ramp, the air traffic controller manages movement and sequencing, and the flight engineer performs the engine checks, but none of them holds the authority to designate the run-up area.
