What Index classification is required for aircraft between 126 and 159 feet in length?

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

Answer: (C)

The classification of aircraft by index is primarily based on their length, which helps determine the level of firefighting and rescue resources required at an airport. Aircraft measuring between 126 and 159 feet in length fall within Index C.

This classification is crucial because it establishes the minimum required number of firefighting vehicles and personnel needed to respond effectively in the event of an incident involving such aircraft. Index C is designed to ensure that appropriate resources, equipment, and training are in place to handle emergencies involving larger aircraft, which typically entail greater challenges in terms of fire suppression and rescue operations.

The specifications and requirements for different indices reflect the increasing complexities and risks associated with rescuing and firefighting for larger aircraft. Hence, the recognition of Index C for aircraft within that specified size range ensures that adequate preparedness measures are in place at airports to safely and efficiently manage emergencies involving these larger aircraft.
