How do the cargo bottles discharge when activated?

The correct answer is based on the operational protocol for the cargo fire suppression system in the Canadair Regional Jet. When the cargo bottles are activated, the discharge process is specifically designed to ensure both effectiveness and safety. One of the bottles releases its content immediately to quickly suppress any fire that may be present, while the second bottle has a delayed discharge that lasts over 60 minutes. This staggered approach allows for additional suppression of any residual heat or potential re-ignition that could occur after the initial response.

The immediate discharge ensures that fires are managed right away, thus minimizing potential damage and risks associated with fire in the cargo area, while the secondary discharge sustains the suppression effort, effectively managing any further fire risks for a longer duration. Understanding this operational detail is crucial for the safe management of cargo compartments on the aircraft, as it reflects the balance between quick response and prolonged protection against ignition.
