How many Air Conditioning System Controllers (ACSC) are present in an aircraft for temperature regulation?

The correct response is based on the design and functionality of the Air Conditioning System Controllers (ACSC) in the A320 aircraft. In this specific aircraft configuration, there are two ACSCs. These controllers work in tandem to ensure optimal temperature regulation throughout the cabin by managing the air conditioning system effectively.

Having two ACSCs provides redundancy, meaning that if one controller fails, the other can still maintain the temperature control, enhancing safety and reliability. This dual controller setup allows for more precise and balanced temperature management in different sections of the aircraft, promoting passenger comfort.

The presence of two ACSCs is standard in many modern aircraft to ensure continuous operation and mitigate the risk of complete system failure, thus reflecting a thoughtful design consideration for both passenger experience and operational safety.
