Crew familiarity has minimal impact on managing errors during flights. Instead, strong non-technical performance is key for effective error management in aviation safety.

Area of Science:

  • Aviation Safety
  • Human Factors in Aviation
  • Crew Resource Management

Background:

  • Crew familiarity, defined by recent shared operational experience, is a recognized safety factor.
  • Limited research exists on the specific mechanisms linking crew familiarity to safety outcomes.
  • This study examined how crew familiarity influences non-technical performance and error management.

Purpose of the Study:

  • To investigate the relationship between crew familiarity and non-technical performance.
  • To analyze the impact of crew familiarity on error occurrence and management.
  • To determine the relative importance of crew familiarity versus non-technical performance in error management.

Main Methods:

  • Data collected during routine commercial airline operations using the Line Operations Safety Audit (LOSA) methodology.

  • Analysis of 154 flights, with 31% operated by unfamiliar crews and 69% by familiar crews.
  • Comparison of error rates, error types, error management, and non-technical performance between familiar and unfamiliar crews.

    • Main Results:

    • Unfamiliar crews exhibited higher error rates and different error types compared to familiar crews.
    • No significant differences in error management were observed between familiar and unfamiliar crews.
    • Crew familiarity did not significantly affect non-technical performance, but non-technical performance strongly correlated with effective error management.

    Conclusions:

    • Crew familiarity has limited operational significance for error management in normal flight operations.
    • The hypothesis that unfamiliar crews pose a higher safety risk was not supported.
    • Non-technical performance is a more critical factor than crew familiarity for effective error management, warranting further research and intervention.
