Which Index classification applies to aircraft measuring between 90 and 126 feet in length?

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

Answer: (B)

The classification for aircraft measuring between 90 and 126 feet in length is Index B. This categorization is part of the Airport Rescue and Firefighting (ARFF) classification system, which is used to determine the appropriate level of firefighting resources and response requirements based on the size and complexity of the aircraft.

Index B includes aircraft that are notably larger than small general aviation aircraft but smaller than those category-sized aircraft classified in Index C. By correctly identifying aircraft in this range, emergency services can ensure they have the right equipment, personnel, and strategies in place to effectively manage emergencies involving these larger aircraft. This classification is essential for safety protocols at airports, particularly when preparing for potential incidents that could arise during takeoff, landing, or ground operations.
