What type of operations are addressed by FAR Part 91?

FAR Part 91 primarily governs the general operating and flight rules for both private and commercial operations. It establishes the standards for the operation of both types of flight activities, ensuring safety and regulatory compliance across various flying environments.

This part of the regulations applies to a wide range of aviation operations, including those conducted by private pilots flying for personal use as well as those performed by commercial operators. This comprehensive set of rules means that pilots must adhere to the same fundamental operating procedures regardless of whether they are flying for personal enjoyment or for compensation.

The reasoning for this choice aligns with the broader intention of FAR Part 91 to cover general aviation, which encompasses both the private and commercial sectors. Understanding how these regulations interlace is crucial for pilots and operators to maintain safety and compliance in their flying activities.
