What does the Central Inflation/Deflation System (CIDS) allow an ARFF vehicle to do?

The Central Inflation/Deflation System (CIDS) is specifically designed to manage the tire pressure of an ARFF (Aircraft Rescue and Firefighting) vehicle effectively. By utilizing CIDS, the vehicle can automatically adjust tire pressure based on the operational requirements, which enables it to maintain optimal performance under various conditions.

This system is particularly beneficial in scenarios where the ARFF vehicle needs to operate on different surfaces, such as on airside operations or rough terrains encountered during emergency responses. The predetermined speeds and stability provided by maintaining the appropriate tire pressure contribute significantly to the vehicle's maneuverability and operational efficiency, ensuring that it can respond quickly and efficiently to emergency situations.

The other options do not accurately reflect the capabilities or functions of CIDS, as it is not designed exclusively for manual operation or only for emergencies; rather, it enhances the overall operational capability of the vehicle across various scenarios.
