Which statement about cargo compartment discharge is correct?

• A. Two bottles are required; the DISCH light comes on about 60 seconds after discharge
• B. The DISCH light comes on about 60 seconds after discharge
• C. The DISCH light comes on immediately after discharge
• D. It cannot be discharged from cockpit

Answer: (B)

Cargo compartment discharge is initiated from the cockpit to release the extinguishing agent into the bay. The system doesn’t light the DISCH indicator immediately; there’s a built‑in delay of about 60 seconds after the discharge occurs for the status to be shown. This delay reflects the time needed for the agent to be released, disperse throughout the bay, and for the system to verify that the discharge has completed. So the DISCH light coming on about 60 seconds after discharge is the correct description. The other points aren’t accurate: you don’t rely on a specific number of bottles for the indication timing, the system isn’t instant, and it can be discharged from the cockpit.
