Which is true about the fire bottle discharge process in cargo areas?

1. Each bottle discharges immediately

2. Bottles discharge at varying rates

3. Only one bottle is activated at a time

4. Neither bottle functions independently

The correct answer is: Bottles discharge at varying rates

The fire bottle discharge process in cargo areas typically involves the bottles discharging at varying rates. This design allows for a more controlled application of the agents used to suppress fire, depending on the nature of the fire, the environment, and the specified safety protocols. By discharging at different rates, the system can effectively manage the suppression effort to target the fire more efficiently, ensuring that resources are used optimally and that the cargo compartment is protected without unnecessary excess. The varying discharge rates also accommodate different fire scenarios, allowing the system to adapt to the needs of the situation. This feature is crucial in maintaining safety and minimizing damage in the event of a fire in the cargo hold, as well as enhancing the overall effectiveness of the fire suppression system onboard the aircraft.
