Lowering the ejection decision height did not improve pilot accuracy in deciding when to eject from aircraft. However, it did increase the tendency for pilots to eject, especially at lower altitudes.

Area of Science:

  • Aviation Psychology
  • Human Factors Engineering
  • Aerospace Safety

Background:

  • Pilot ejection decisions are critical for safety, despite advanced aircraft automation.
  • Ejection decision height is a key factor influencing pilot judgment.
  • The Royal New Zealand Air Force explored lowering ejection heights to provide more decision time.

Purpose of the Study:

  • To investigate the impact of reduced ejection decision height on pilot accuracy.
  • To determine if lowering ejection decision height affects the bias towards ejecting.
  • To assess the relationship between ejection decision height and pilot judgment accuracy.

Main Methods:

  • Thirty male pilots participated in simulated flight sorties.
  • Scenarios were designed to either require or not require ejection.

  • Pilots were randomly assigned to ejection decision heights of 10,000, 6,000, or 3,000 ft.

    • Main Results:

    • Ejection decision height did not affect the accuracy of ejection decisions.
    • Lowering ejection decision height increased the bias towards ejecting.
    • Pilot experience correlated with decisiveness in judgments.

    Conclusions:

    • Reducing ejection decision height does not enhance pilot accuracy in discriminating ejection scenarios.
    • Lower ejection decision heights increase pilot bias to eject.
    • Experience influences pilot judgment confidence and decisiveness.
