Which practice is typical for Part 135 charter operations that differs from Part 91 private operations?

• A. Specific equipment, crew duties, and operating requirements
• B. No regulatory differences
• C. No training requirements
• D. Unlimited flight hours

Answer: (A)

Part 135 charter flights operate under a framework that prescribes the exact equipment, crew duties, and operating procedures to ensure safety when carrying passengers for hire. This level of detail is needed because commercial charters are regulated as air carrier operations, so FAA approvals, equipment configurations, crew qualifications, and documented procedures are all required and standardized. In contrast, Part 91 private operations have much more flexibility and fewer prescriptive rules, since they are not-for-hire and not tied to the same mandatory OpSpecs or standardized operating procedures. That’s why specifying equipment, crew duties, and operating requirements is the distinguishing practice for Part 135. The other statements don’t fit because there are regulatory differences between Part 135 and Part 91, training is required for Part 135 operations, and flight hours are not unlimited due to flight-time limits and rest requirements.
