CPL Air Law Practice Questions - CASA Commercial Pilot Licence (Aeroplane) - Air Law (CLWA) Exam

Part 135 completely replaces Part 91 for commercial operations, meaning Part 91 rules do not apply at all. Part 91 applies only to private operations, whereas Part 135 applies to both private and commercial operations. Part 91 establishes the baseline rules for all flight operations, while Part 135 imposes additional, more stringent requirements specifically for small aeroplane commercial operations. Part 91 and Part 135 are independent codes, and pilots only need to comply with the one selected on the flight plan.
