  1. INTRODUCTION to HFDM • Presented to: • IHST Accident Intervention WORKSHOP By: Captain Mike Pilgrim FDM Manager CHC Helicopter Services Co-Chair Global HFDM Steering Group Date: 4th March 2013 www.HFDM.org

  2. Global HFDM Steering Group • Vision: • Routine and effective utilisation of HFDM in a just culture environment across the global helicopter industry.

  3. Global HFDM Steering Group • Mission: • Improve helicopter safety through provision of focus and leadership on issues concerning the manufacture, provision, support and operation of HFDM systems.

  4. The Definition of Flight Data Monitoring. Flight Data Monitoring (FDM) is the systematic, pro-active use of digital flight data from routine operations to improve aviation safety. Flight Data Monitoring (FDM) programmes assist an operator to identify, quantify, assess and address operational risks.

  5. Why HFDM? Accidents REACTIVE Serious incidents Active Failures and Latent Threats Severity of event Minor incidents PROACTIVE? Routine operations FREQUENCY OF EVENT

  6. FDM IIII O O O O This is Why

  7. Flight Data Monitoring Data will only be worth anything if the aircraft is actually doing something. • What do we mean by Flight? So ‘flight’ is from power on to power off

  8. Flight Data Monitoring Anything about the state of the aircraft that can be recorded: • and Data? • Airspeed • Rate of climb/descent • Flight control positions • Engines / rotors / temps & pressures

  9. Flight Data Monitoring Careful analysis of groups of data for indications of anything undesirable. • What about monitoring? So what does it look like?

  10. Flight Data – Take-Off

  11. Flight Data – Altitude Altitude

  12. Flight Data – Pitch Pitch Attitude

  13. Rate of Descent 700ft 150ft -1000fpm 30 SECS

  14. How do we get the data? Solid State Quick Access Recorder

  15. Aircraft without FDRs Stand alone units Power Earth Geospatial Digital (Optional) Video (Optional) Engine Data

  16. Now I have the knowledge • Start compiling your trend information • Itsnot about individual incidents • Aggregate the event types • Produce readable reports • Involve your staff • Don’t talk about individual events in terms of the crews who flew them

  17. Flight Data Monitoring • Demonstrable safety: • Don’t just think you’re safe, KNOW YOU’RE SAFE

  18. Example Overtorque on take-off

  19. Plotting Engine Tq against IAS

  20. Tq vs IAS graph

  21. Example Potential Dynamic Roll-Over

  22. Example 1Close to Roll-over

  23. Rolling Moment Rolling moment with left cyclic applied due to inclined main rotor and offset flapping hinges. Rolling moment due to the tail rotor thrust with left pedal applied. CF CF

  24. Rolling moment with left cyclic applied due to inclined main rotor and offset flapping hinges. CF CF Rolling moment due to the tail rotor thrust with RIGHT pedal applied.

  25. Rolled over aircraft

  26. High Risk Area
