Off-line charter operations are operated under __________ rules.

Off-line charter operations are operated under __________ rules.

• A. Part 121
• B. Part 135
• C. Domestic Charter Rules
• D. Supplemental

Answer: (D)

Off-line charter operations are flights run outside a carrier’s published schedule to meet a specific charter need. In FAA terms, these are treated as Supplemental operations rather than part of the scheduled Part 121 system or the standard on-demand Part 135 model. The Supplemental category covers non-scheduled flights that actually “supplement” the carrier’s regular service, with its own set of operational controls, crew and maintenance oversight, and safety requirements. Domestic Charter Rules isn’t a formal designation, and Part 121 and Part 135 refer to different operating frameworks, not this off-line charter model.
