What does Part 91 of the FARs discuss?

Part 91 of the Federal Aviation Regulations (FARs) primarily addresses general operating and flight rules applicable to civil aviation. This section outlines the responsibilities of pilots, aircraft operators, and air traffic control in terms of operational procedures, air traffic rules, and safety protocols that must be followed during both visual and instrument flight rules.

Understanding Part 91 is crucial for pilots, as it lays the fundamental legal framework that governs most aspects of flying, including rules regarding visibility, minimum safe altitudes, and the operation of aircraft in various airspace classifications. Familiarity with these regulations ensures that pilots can operate safely and within the law.

While other parts of the FARs cover maintenance requirements for aircraft, flight instructor qualifications, and accident reporting, those subjects are governed by different sections of the regulations. Thus, focusing on operational and flight rules is the central theme of Part 91, making it the correct answer to the question.
