What is the minimum ARFF index level for a certificated airport?

• A. Index A
• B. Index B
• C. Index C
• D. Index D

Answer: (A)

ARFF index levels describe the firefighting capability an airport must have, increasing as the size of aircraft served and the potential risk grow. For a certificated airport, the baseline requirement is the lowest ARFF index category, ensuring there is a basic level of equipment and trained personnel to handle typical incidents. Airports that host larger aircraft or more traffic may need higher ARFF levels to match the greater risk and response needs. So the minimum level is the baseline category, with higher levels only required when operations demand it.
