Is there any fire extinguishing for the avionics compartment?

• A. No
• B. Yes, for avionics fire only
• C. Yes, with a portable extinguisher
• D. Only if smoke detected

Answer: (A)

The avionics compartment on an A320 does not have a dedicated fire extinguishing system. Protection is provided by detecting smoke and by the crew taking action to isolate and power down the avionics to starve a fire and limit smoke, rather than discharging a fire extinguisher into the bay. There is no automatic extinguisher release, and portable extinguishers are not used as a standard means to suppress an avionics fire. So, there is no fire extinguishing for the avionics compartment.
