The forward compartment has only an isolation valve switch and a temperature selector.

• A. False
• B. True
• C. Not specified
• D. Unknown

Answer: (B)

In the A320 environmental control layout, the forward compartment is treated as a simple, separately controllable zone. The only controls located there are an isolation valve switch and a temperature selector. The isolation valve allows you to shut off airflow to that forward area if needed, such as to maintain a specific condition or to isolate it from the rest of the system. The temperature selector lets you set the desired temperature for air delivered to that compartment. All other HVAC functions are managed by the centralized packs and cockpit controls, so there aren’t additional controls in the forward compartment. That’s why the statement is true.
