What indicator confirms that discharge to a cargo compartment has occurred?

• A. The DISCH light comes on
• B. The red disc appears
• C. The ECAM countdown starts
• D. The APU fire warning resets

Answer: (A)

The key idea here is how the cargo fire suppression system confirms that the extinguishing agent has been released. When you discharge the extinguishing agent into a cargo compartment, a dedicated indicator labeled DISCH lights up to show that the discharge sequence has occurred. This visual feedback is what you rely on to verify that the system has activated and the agent has been released into the compartment. The other options don’t indicate this event. A red disc indicator isn’t the established cue for cargo discharge, the ECAM countdown is a general system monitoring tool rather than a discharge confirmation, and resetting an APU fire warning pertains to the APU fire scenario, not the cargo compartment discharge.
