Flight safety assessment based on an integrated human reliability quantification approach.

Area of Science:

• Aviation Safety
• Human Factors Engineering
• Risk Management

Background:

• Human error is a significant risk factor in flight safety.
• Traditional Human Error Assessment and Reduction Technique (HEART) has limitations in quantifying human error and lacks remedial measures.
• HEART's reliance on single expert judgment leads to imprecise Assessed Proportion of Affect (APOA) calculations.

Purpose of the Study:

• To propose an integrated human error quantification approach for flight safety assessment.
• To overcome the limitations of traditional HEART, specifically imprecise APOA calculation and lack of remedial measures.
• To enhance the accuracy and feasibility of human reliability assessment in aircraft operations.

Main Methods:

• Developed an integrated human error quantification approach.
• Utilized an improved Analytic Hierarchy Process (AHP) method to determine APOA values.
• Fused AHP-derived APOA values with the HEART method to calculate human error probability.
• Conducted a flight task to assess human reliability.

Main Results:

• The proposed method provides a reasonable and feasible tool for quantifying human error probability in aircraft manipulation.
• Successfully identified critical error-producing conditions impacting flight safety.
• Provided specific improvement measures for high-error-rate operations.
• Demonstrated enhanced accuracy in human reliability assessment compared to traditional methods.

Conclusions:

• The integrated approach effectively quantifies human error probability and assesses flight safety.
• The method offers valuable insights for identifying and mitigating human error factors in aviation.
• Implementation of the proposed measures can significantly reduce human error and improve overall flight safety.
