Which PCAR part provides the requirements for Philippine commercial air transport operators?

The correct choice is based on the specific structure of the Philippine Civil Aviation Regulations (PCAR), which are essential for the governance of aviation operations in the Philippines. Part 9 of the PCAR specifically addresses the requirements for commercial air transport operators. This includes regulations related to the operation of aircraft, maintenance, safety, licensing, and operational protocols that must be followed by commercial operators to ensure compliance with aviation standards and safety measures.

While other parts of the PCAR may cover aspects related to aviation in general, such as airworthiness or safety management systems, Part 9 is dedicated to the operational requirements for commercial transport, making it the most relevant section for operators in that sector. It sets the framework that aviation companies must adhere to in order to operate legally and safely within the Philippine airspace.
