Isolation switch Auto leads to automatic closing of isolation valves and ECAM amber cross-line when cargo smoke is detected?

• A. Manual
• B. Auto
• C. Off
• D. On

Answer: (B)

The switch in Auto is designed to provide automatic protection in a cargo smoke event. When cargo smoke is detected, the system automatically closes the isolation valves and the ECAM shows an amber cross-line to warn the crew that the cargo bay has been isolated. This quick, automatic action helps prevent smoke from spreading through the ventilation system and gives flight crew time to manage the situation while the bay is sealed. In manual, a pilot would have to operate the valves themselves; in off, the automatic isolation function is not active; and the other position is not the one that enables automatic response to smoke.
