What does Part 139 Subpart C specifically address?

Part 139 Subpart C specifically addresses the Airport Certification Manual (ACM). The ACM is a critical document required for the certification of airports that serve scheduled passenger operations. It outlines the safety and operational standards that must be adhered to at the airport to ensure compliance with Federal Aviation Administration (FAA) regulations.

The purpose of the ACM is to provide guidelines on various airport operations, including safety management, personnel training, emergency procedures, and maintenance of airport facilities. By requiring an Airport Certification Manual, the FAA ensures that airports maintain high safety standards that protect both passengers and aircraft operations.

Understanding the importance of the ACM is essential for airport management and certification processes. In contrast, the other options do not pertain directly to the specific regulatory framework outlined in Part 139 Subpart C. This distinction highlights the role of the ACM as a comprehensive guide to airport operations that are in compliance with federal regulations.
