On a KC-10, what is the propeller intake danger area?

The area around the propeller intake of a KC-10 is critical for safety, as the risk of injury or damage increases the closer one gets to the aircraft. The correct response indicates that the propeller intake danger area extends within 20 feet of the aircraft.

This range is established to ensure that personnel are kept at a safe distance from potentially hazardous conditions associated with the operation of the aircraft's engines, which can include strong airflow and noise that can cause injury. Understanding this danger zone is essential for maintaining safety on the flight line and during ground operations, particularly when approaching or working near the aircraft.

Knowing the specific distance of 20 feet helps crews and personnel to maintain proper spacing and adheres to safety protocols, minimizing the likelihood of accidents. The other choices provide different distances that do not reflect the actual danger area, which has been defined through operational guidelines and safety standards for the KC-10.
