What is the propeller intake danger area for a C-17 aircraft?

The propeller intake danger area for a C-17 aircraft is an important safety consideration due to the powerful engines and the potential for ingesting objects or personnel into the engine intakes. The correct distance designated as a safe clearance area is 25 feet. This distance is established to ensure that individuals and equipment remain outside of the danger zone where the forces generated by the engines may pose a risk.

Understanding the danger areas around aircraft is crucial for ensuring safety during operations, maintenance, and any activities conducted near the aircraft. The specified distance serves to protect both personnel and equipment, as it minimizes the risk of damage from the forces associated with the engines and prevents accidental ingestion of materials or possible injuries that could occur if someone strayed too close.

In contrast, the other distances listed do not reflect the established safety guidelines for the C-17's propeller intake, making them inappropriate answers in this context.
