Which regulatory document outlines the performance standards for hybrid ARFF units at certificated airports?

• A. FAR Part 135
• B. FAR Part 139
• C. FAR Part 121
• D. FAR Part 145

Answer: (B)

The correct answer is the regulatory document that specifically addresses the standards for airport operations, including aircraft rescue and firefighting (ARFF) requirements, at certificated airports. FAR Part 139 is the section of the Federal Aviation Regulations that establishes the certification requirements for airport operators, detailing the necessary safety measures and standards to ensure passenger safety and efficient operations, including the performance standards for firefighting and rescue equipment.

This includes guidelines for ARFF units, making it crucial for airport operators to meet these standards to maintain certification and ensure preparedness for potential emergencies. Other parts of the FAR, such as Part 135, Part 121, and Part 145, focus on other aspects of aviation operations, such as commuter and on-demand operations, scheduled air transportation, and repair stations, respectively; they do not specifically address the requirements for ARFF units at certificated airports. This focus on airport operations and emergency readiness in FAR Part 139 establishes it as the primary regulatory framework for hybrid ARFF units and their performance standards.
