Which personnel is NOT included in the supervisory personnel for mass operations from a C-17?

In the context of mass operations from a C-17, supervisory personnel play critical roles in ensuring safe and effective operations. The loadmaster, safety personnel, and jumpmaster all have specific responsibilities that directly contribute to the oversight of the aircraft’s cargo and personnel.

The loadmaster is responsible for managing the load of the aircraft, ensuring that it is balanced, properly secured, and that all safety protocols are followed. Safety personnel focus on risk management, ensuring that all operations adhere to safety standards, thereby protecting both personnel and assets. The jumpmaster oversees the parachutists during their exit from the aircraft, ensuring that all procedures are followed for a safe jump.

In contrast, the navigator, while essential for the aircraft's flight operations, primarily focuses on determining the aircraft's route and managing navigational tasks. The navigator does not typically have a supervisory role concerning the personnel and cargo during mass jumps. Thus, the navigator is not included in the supervisory personnel for the specific operations of jumping from the C-17, making this response appropriate.
