What ARFF Index category is assigned to aircraft that are less than 90 feet?

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

Answer: (A)

Index A is assigned to aircraft that are less than 90 feet in length. This classification is part of the Aircraft Rescue and Firefighting (ARFF) Index system, which provides a standardized framework for determining the level of firefighting resources and response required for various aircraft sizes in the event of an emergency.

Within the ARFF Index, different categories are established based on the dimensions and characteristics of aircraft, with Index A designated for the smallest category. This classification helps ensure that the appropriate level of resources is prepared and available in case of an incident involving smaller aircraft, which may require less intensive firefighting measures compared to larger aircraft.

Other indices correspond to larger aircraft sizes, which necessitate a greater number of firefighting apparatus and crew. The use of these indices helps fire departments organize their response effectively based on the specific needs and risks associated with different aircraft types.
