ARFF – FAA INDEX A
Aircraft Rescue & Firefighting Vehicles
Operational Profile
FAA Index A ARFF vehicles are intended for airports serving smaller transport category or general aviation aircraft where required agent quantities and response times are lower, but rapid initial knockdown remains critical. These vehicles prioritize maneuverability, acceleration, and immediate agent delivery while maintaining compliance with FAA Part 139 performance expectations. Emergency Response Depot provides FAA Index A ARFF vehicles and compliance support for general aviation and small commercial airports throughout Pennsylvania and the Northeast.
