Will there be any indication that the lavatory fire bottle has been discharged on the flight deck?

• A. No
• B. Yes, a light will illuminate
• C. It will beep
• D. Maintenance will be required to confirm

Answer: (A)

When a lavatory fire bottle is discharged, there is no cockpit indication. The extinguishing bottle is a self-contained device, and its discharge status does not trigger a flight-deck warning light or audible alert. In the cockpit, warnings come from fire detectors indicating a fire, not from the act of releasing the extinguisher itself. After the flight, maintenance will check and restore or replace the bottle as needed; there isn’t a flight-deck confirmation that it has discharged.
