What is a primary function of the cargo fire protection system in case of an aft cargo fire?

1. To discharge fire extinguishing agents

2. To activate cabin alarms

3. To ensure crew evacuation

4. To initiate an emergency landing procedure

The correct answer is: To discharge fire extinguishing agents

The primary function of the cargo fire protection system in the event of an aft cargo fire is to discharge fire extinguishing agents. This system is specifically designed to detect and suppress fires that may occur within the cargo holds of the aircraft. Upon detecting a fire, the system automatically releases extinguishing agents to control and mitigate the fire, thus protecting the integrity of the aircraft and ensuring the safety of both the crew and passengers. Other options, while important in their own contexts, do not serve as the primary functions of the cargo fire protection system. Activating cabin alarms, ensuring crew evacuation, and initiating emergency landing procedures are crucial steps that may follow the detection of a fire, but they are not directly managed by the cargo fire protection system itself. Instead, these actions are part of the broader emergency procedures and responsibilities of the flight crew in response to alerts from the fire protection system.
