Recording of cockpit video and audio data may permit enriched replay of key flight events, encouraging more crew interaction during debriefing, analysis, reflection and self-discovery. These technologies may offer additional insights to airline Flight Operations Quality Assurance (FOQA) staff or accident investigation teams. However, the flight crew may perceive such systems as invasions of privacy and are concerned about possible misuse of information obtained from cockpit video recorders.

Such information may eventually be transmitted to the ground in real-time.

Potential hazard

  1. Diversion of scarce safety resources away from accident prevention to post-mortem forensics
  2. Crews “flying by the book” though that may not be the appropriate response in unexpected situations.Fleet-wide installation may cost … per aircraft for systems that feature:
  3. The light range: Even within a single picture, the range of illumination can vary by a factor of 100,000 between the brightest scenes above the clouds to a dimmed passenger cabin.
  4. The temperature range: The temperature can vary from -140 degrees F on the aircraft’s exterior to more than 120 degrees F inside an aircraft parked in the desert.
  5. The power supply: This can vary and is subject to dropouts during engine start. Cameras would need to kick in within 50 milliseconds of aircraft power loss
  6. Cabin pressure changes: The rate of change in cabin pressure can be rapid, should decompression occur.
  7. High reliability and ease of maintainability: These are factors that must be considered.
