According to the ARFF index, what index is designated for aircraft lengths between 90 to 126 feet?

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

Answer: (B)

The correct index designated for aircraft lengths between 90 to 126 feet is Index B. The ARFF (Airport Rescue and Firefighting) index categorizes aircraft based on their size to ensure that appropriate firefighting resources are available for each type.

Index B specifically addresses medium-sized aircraft, which fall within this length range, ensuring that firefighting personnel are equipped with the right vehicles and equipment to respond effectively to incidents involving these aircraft. This categorization is vital for prioritizing resources and tailoring response strategies according to the potential risks associated with different aircraft sizes. The specifications laid out in the ARFF index help maintain aviation safety and enhance emergency response effectiveness at airports.
