Summary

Pilot decision-making is influenced by how they assess nonroutine events. This study found individual assessment tendencies were consistent but unaffected by stress levels in simulations. A new questionnaire was developed to measure life stress.

Area of Science:

  • Psychology
  • Human Factors Engineering
  • Aviation Psychology

Background:

  • Accurate assessment of nonroutine event consequences is crucial for pilot decision-making.
  • Measuring life stress presents significant challenges in psychological research.
  • Individual differences in assessing event consequences may impact performance.

Purpose of the Study:

  • To investigate the over/underassessment of nonroutine event consequences in pilots.
  • To introduce and validate the Life Events Questionnaire (LEQ) for stress measurement.
  • To examine the relationship between life stress levels and consequence assessment.

Main Methods:

  • Development and application of the Life Events Questionnaire (LEQ).
  • Utilizing an artificial air traffic control simulation.

  • Assessing individual tendencies in over/underassessing consequences of nonroutine events.

    • Main Results:

    • Individual tendencies to over/underassess consequences were consistent.
    • Life stress levels did not affect consequence assessment in the simulation.
    • High stress subjects reported significantly higher chronic stress than acute stress (p < 0.001).

    Conclusions:

    • Pilot's assessment of nonroutine events shows intra-individual consistency.
    • Life stress levels, as measured by LEQ, did not influence this assessment tendency in the simulated environment.
    • Chronic stress is a more significant factor than acute stress for individuals experiencing high life stress.
