What do pilots use to signal their intent during a normal engine run-up?

• A. Hand gestures
• B. Vocal commands
• C. Two fingers back and forth
• D. Body movements

Answer: (C)

During a normal engine run-up, pilots utilize specific signals to communicate their intentions, and the signal of two fingers held up and moved back and forth is a recognized standard for indicating that the engine run-up is complete or that everything is functioning as expected. This visual cue is clear and simple, allowing for effective communication between the pilot and any supporting crew or personnel on the ground, particularly in environments where vocal commands may not be easily heard due to engine noise or other distractions. It's important for pilots to establish clear and unambiguous signals, especially in complex or noisy scenarios, which is why this particular gesture is preferred. The other options do not conform to the standardized methods used during this operation, as hand gestures, vocal commands, and body movements may lack the clarity and precision required for effective communication in the cockpit environment.
