What must hybrid ARFF units comply with?

• A. ICAO regulations
• B. FAR Part 139
• C. NFPA guidelines
• D. FEMA standards

Answer: (B)

Hybrid Aircraft Rescue and Fire Fighting (ARFF) units must comply with FAR Part 139, which outlines the requirements for aircraft rescue and firefighting services at airports. This regulation establishes the standards that airports must meet to ensure the safety and emergency response capabilities at commercial airports, including the necessary equipment and training for personnel.

FAR Part 139 specifies performance standards that ARFF services must meet based on the type of aircraft operating at the airport and the specific risks associated with those operations. Compliance ensures that the airport can effectively respond to aircraft emergencies, providing the necessary resources to protect public safety and minimize the potential impact of aviation incidents.

While ICAO regulations, NFPA guidelines, and FEMA standards may provide additional standards and recommendations for emergency services and safety, FAR Part 139 is the specific regulatory framework that governs the operational requirements for airports in relation to fire protection and rescue services, including hybrid ARFF units.
