Operating Requirements: Commuter and On-Demand Operations are regulated by which Part?

• A. 14 CFR Part 135
• B. 14 CFR Part 121
• C. 14 CFR Part 91
• D. 14 CFR Part 73

Answer: (A)

Commuter and on-demand operations fall under 14 CFR Part 135. This part specifies the operating requirements for charter and on-demand air carriers, including how these operators are certificated, the qualifications and duties of flight crews, the equipment and maintenance standards required, and the operating limitations appropriate for smaller, non-scheduled services. It differentiates these operations from Part 121, which governs scheduled air carriers with larger aircraft and more prescriptive procedures, Part 91, which covers general aviation and unscheduled operations not conducted by a certified carrier, and Part 73, which deals with special use airspace rather than operator standards.
