What maximum distance should you maintain from the propeller intake of a C-17?

The correct distance to maintain from the propeller intake of a C-17 is 25 feet. This distance is crucial for safety reasons as it helps ensure that personnel are kept clear of potential hazards associated with the aircraft's operation, such as propeller wash and suction effects at the intake. The propeller creates significant airflow, which can affect the stability of individuals and equipment nearby. Maintaining this distance reduces the risk of injury caused by the intense wind blast or the potential for a person inadvertently being drawn into the intake area, which is highly dangerous due to the powerful operation of the aircraft's engines. This guideline is established to protect both personnel and equipment while ensuring safe operations around the aircraft.
