Which ARFF Index category is used for aircraft that are between 159 and 200 feet?

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

Answer: (C)

The ARFF Index categorization is based on the length of the aircraft, with different indices representing different ranges. The category specifically for aircraft that measure between 159 and 200 feet in length is Index D. This classification is crucial because it determines the level of firefighting resources and the type of response required in the event of an incident involving an aircraft of this size.

Understanding the categories helps in planning and ensuring that appropriate measures are in place to effectively manage emergencies involving various aircraft sizes. Index D is therefore the correct designation for aircraft in this length range due to the increased structural and fire risks presented by larger aircraft, requiring a more comprehensive response strategy.
