How are ARFF Index classifications primarily determined?

• A. Fire department resources
• B. Aircraft wingspan
• C. Passenger capacity
• D. Foam application rates

Answer: (B)

The ARFF Index classifications are primarily determined by the aircraft wingspan because the wingspan is a key factor that indicates the size of the aircraft and helps establish the necessary firefighting response requirements. The ARFF Index categorizes airports based on the types of aircraft that operate there, and larger aircraft with greater wingspans present different challenges, including the volume of fuel they may carry and the potential for a larger fire footprint in the event of an accident.

This classification impacts the number of firefighting resources that must be available at an airport, such as the types and quantities of fire apparatus, the amount of firefighting foam, and the overall operational readiness needed to effectively respond to incidents involving larger aircraft. Understanding the significance of wingspan allows airport fire officers to ensure they have the appropriate resources and training to deal with emergencies related to specific aircraft types.
