Which document outlines the regulations a flight engineer must follow?

The Federal Aviation Regulations (FAR) serves as a comprehensive set of rules provided by the Federal Aviation Administration (FAA) that governs all aspects of civil aviation in the United States. These regulations cover various areas, including pilot certification, maintenance, operations, and safety standards, which are crucial for flight engineers in ensuring compliance and safe operation of aircraft.

Flight engineers are required to adhere to these regulations to maintain the safety of aircraft operations and themselves during the flight process. The FAR specifically outlines the legal responsibilities and operational guidelines for flight engineers, making it the most authoritative source for the standards they must follow.

Other options, while they cover important aspects of aviation, do not serve as the primary regulatory framework specific to flight engineers. The Air Commerce Act relates more to the promotion of air commerce, the Aviation Safety and Security Act focuses on broader safety measures, and the Aircraft Pilot Manual is designed for pilot use and does not contain the regulatory framework necessary for flight engineers. Thus, the FAR is the key document that establishes the applicable regulations for flight engineers.
