What should occur when a hangfire is active, according to indicator behavior?

• A. The ‘HANGFIRE’ indicator should appear and be noted three times
• B. The system should automatically switch to backup target tracking
• C. The launcher should self-diagnose and reset
• D. No action is required if a hangfire occurs

Answer: (A)

When a hangfire occurs, you’re dealing with a delayed ignition condition in the launcher. The system’s warning should be shown as a HANGFIRE indicator and it must be noted three times to confirm that the hazard is real and not a transient signal. The repeated indication ensures the crew cannot overlook the warning and prompts the required safety actions before any further actions with the launcher. Other options don’t fit because hangfire is about the firing event itself, not target tracking; a self-diagnose/reset or no action would not address the hazardous delay and could compromise safety.
