AIRPORT ARFF INDEX
How it works and how it affects your required aircraft rescue and firefighting (ARFF) training
calculates the ARFF index
(five possible indexes) by considering the length
of aircraft and the average daily departures
of aircraft: â€œIf there are five or more average daily departures of aircraft in a single index group serving that airport, the longest aircraft with an average of five or more daily departures determines the Index required for the airport. When there are fewer than five average daily departures of the longest air carrier aircraft serving the airport, the Index required will be the next lower Index group than the Index group prescribed for the longest aircraftâ€. In other words, it says that at least five departures a day are needed for the biggest aircraft to affect the index category.
In Part 139.317 is detailed how to organize the vehicles and their contents, not leaving room for doubt over those issues. Plus, it is explained when a turret is to be installed.
- Index A airports (Aicraft length < 90 ft (≈27,4m)) need at least one vehicle.
- Index B airports (Aircraft length 90 ft ≤ L < 126 ft (≈38,4m)) need one to two vehicles, depending on the equipment layout.
- Index C airports ((Aircraft length 126 ft ≤ L < 159 ft (≈48,6 m)) need two to three vehicles, depending on the equipment layout.
- Index D airports ((Aircraft length 159 ft ≤ L < 200 ft (≈61 m)) need three vehicles.
- Index E airports ((Aircraft length ≥200 ft (≈61 m)) need three vehicles.
Operators of Part 139 airports must provide aircraft rescue and firefighting (ARFF) services during air carrier operations that require a Part 139 certificate. The guidance and resources below address ARFF training, ARFF vehicles, and other aviation fire and rescue requirements
