What must pilots abide by despite the applications listed in the 7110.65?

The correct answer emphasizes the importance of the Code of Federal Regulations (CFRs) as the foundational legal framework governing aviation operations. Pilots are obligated to adhere to CFRs because they represent federal regulations that dictate various aspects of aviation safety, operational protocols, and the responsibilities of pilots and air traffic professionals. These regulations are legally enforceable, and compliance ensures the safety and efficiency of flight operations.

The 7110.65 provides guidelines for air traffic control procedures and practices but does not supersede the legal requirements established in the CFRs. Pilots must operate within the parameters set by federal law, which includes adherence to the rules outlined in the CFRs, even when specific instructions or guidelines from the 7110.65 suggest otherwise or provide additional context. Understanding this hierarchy of regulations is key to safe and compliant operation in the aviation industry.
