Exceptions under Part 91 compared to Part 135 operations include?

In this context, understanding Part 91 and Part 135 is crucial for distinguishing the different types of operations in aviation regulations. Part 91 encompasses general aviation operations, while Part 135 governs commercial operations.

One of the key characteristics of Part 91 operations is that they often involve non-commercial flights where various rules and exceptions apply. For instance, passenger identification checks are not a regulatory requirement for Part 91 operations, allowing greater flexibility in terms of who can board the aircraft. This flexibility does not apply under Part 135 due to the commercial nature of those operations, where ID checks for passengers are necessary.

Additionally, in Part 91 operations, pilots and crew members are not mandated to maintain direct communication with air traffic control or ground facilities, unlike Part 135, where such communication is critical for ensuring safety throughout commercial flights.

The non-commercial flight rules under Part 91 provide an array of allowances that are not found in the stricter guidelines of Part 135, further solidifying the distinction between these two regulatory frameworks. All these points collectively highlight the exceptions within Part 91 operations compared to the more regulated environment of Part 135, emphasizing the correct answer that encapsulates these differences.
