Flight History

Flights include preparation and return to ground across CMC leg boundaries. Ends are last recorded events, not confirmed shutdowns. Gaps over 6 hours split uncertain sessions. Plain Set means a later clear was recorded in the same flight/session; a filled Set badge means none was recorded before that session ended. Hover over the status for details.

📖 About the Fault Decoder

This decoder analyzes FHDB fault patterns and provides insights based on:

  • FDE Correlations - Links faults to Flight Deck Effects (pilot CAS messages)
  • Pattern Analysis - Identifies intermittent faults suggesting wiring issues
  • Fault Database - Decoded meanings for common fault codes
  • ATA References - Chapter numbers for manual lookup

Note: The FHDB uses proprietary internal codes. Full translation to ATA format requires manufacturer's mapping table. This decoder provides best-effort interpretation based on pattern analysis. Always refer to the official Honeywell Flight Line Maintenance Manual for authoritative troubleshooting procedures.
