Which statement correctly describes Part 135 operations in relation to Part 91?

Which statement correctly describes Part 135 operations in relation to Part 91?

• A. Part 135 governs on-demand air taxi and commuter operations; Part 91 governs general aviation.
• B. Part 135 is unrelated to on-demand services; Part 91 covers all aviation.
• C. Part 135 regulates on-demand air taxi and commuter operations; Part 91 governs general aviation.
• D. Part 135 prohibits passenger-carrying flights.

Answer: (C)

The main idea here is how the FAA divides flight operations into different rule sets. Part 135 is the regime for commercial, on-demand air taxi and commuter flights—those booked for hire as-needed. Part 91 covers general aviation, which includes most non-commercial flights, such as private and corporate flying not conducted for hire. So, Part 135 regulates on-demand air taxi and commuter operations, with the accompanying requirements for certification, aircraft, crew qualifications, operating rules, and recordkeeping. Part 91 governs general aviation, which is generally non-commercial and not conducted for hire. This distinction explains why passenger-carrying flights can be either under Part 135 (on-demand/commercial) or under other parts for different kinds of operations, while general aviation remains under Part 91. Other statements aren’t correct because Part 135 is not unrelated to on-demand services, and it does not prohibit passenger-carrying flights; it enables them under the appropriate operating framework.
