Under what circumstances does DFIRS deploy the stored flight data?

• A. Only after a crash
• B. Before the aircraft crashes or upon aircraft impact
• C. During routine maintenance
• D. When commanded by the pilot

Answer: (B)

DFIRS is designed to preserve critical flight information when things go wrong. It automatically deploys the stored data before the aircraft crashes or at the moment of impact, so the data remains intact and recoverable for investigation even if the aircraft is severely damaged. This automatic, event-driven action ensures data availability without needing maintenance actions or pilot commands.
