A pilot returning from an extended flight is responsible for submitting the completed refueling slip to which officer?

The correct choice is the Material Control Officer. In Navy logistics, the Material Control Officer is responsible for overseeing the management of materials, including aviation fuel and other necessary supplies used by aircraft. The refueling slip is a critical document that records the amount of fuel consumed or needed for the aircraft, and it directly affects inventory and logistics operations.

When a pilot returns from a flight, submitting the completed refueling slip to the Material Control Officer ensures that fuel records are accurately maintained and that any discrepancies in fuel usage can be addressed. This helps maintain operational readiness and ensures accountability for fuel resources. Proper documentation is vital for logistics tracking, inventory control, and financial accountability within the naval aviation community, making the role of the Material Control Officer essential in this process.
