Evaluating Human Error and Designing Resilient Systems: An Aviation Safety Report

Overview

This individual report is designed to assess your understanding of Human Factors (HF) in aviation, your ability to critically analyse HF contributions to accidents, and your capacity to propose safety-enhancing policies. The report is divided into two parts, aligning with the course learning outcomes.

• Word Limit: 1500–2000 words (maximum 20 pages including references).
• Referencing: Harvard style is mandatory.
• 2. Learning Outcomes Assessed

• LO2: Identify the characteristics of human factors in the aviation industry.
• LO3: Evaluate the human factors contributing to incidents/accidents.
• LO5: Design policies that reduce the effects of human factors on active failures.

3. Questions guidelines :

From the two research articles provided (available in the assignment materials on Moodle), select ONE. Critically analyse its content by responding to the seven questions below. Your responses should reflect a comprehensive understanding of the article by integrating its findings with relevant theoretical frameworks from the course, as well as with practical aviation scenarios and case studies explored during our five-day intensive program. Article Selection:

Article A: Salas, E., Wilson, K. A., Burke, C. S., & Wightman, D. C. (2006). Does crew resource management training work? An update, an extension, and some critical needs. Human factors, 48(2), 392-412.

Article B: Wiegmann, D. A., & Shappell, S. A. (2001). Human error analysis of commercial aviation accidents: Application of the Human Factors Analysis and Classification System (HFACS). Aviation, space, and environmental medicine, 72(11), 1006-1016.

Part 1: Critical Analysis of Research Articles

Questions :

1. Foundations and Frameworks: Summarize your chosen article's main argument and key findings. Then, identify and explain two specific human factors models or theories from the five-day course (e.g., Reason's Swiss Cheese Model, SHELL Model,CRM Pyramid) that are directly relevant to or supported by the article's conclusions. Provide a detailed rationale for your choices.

1. Error Analysis and Classification: Using concepts from Day 2 (Accident
   Theory) and Day 3 (Human Error), analyze how the article approaches the understanding or classification of human error. For Article A, discuss how CRM training addresses different error types (skill-based, decision-based, etc.). For Article B, explain how HFACS categorizes errors and unsafe acts, linking these to course definitions and classifications.
2. Training and Mitigation Strategies: Evaluate the article's perspective on mitigating human error. For Article A, critique its assessment of CRM training effectiveness. For Article B, discuss the implications of the HFACS analysis for designing preventive measures. In your answer, reference specific CRM goals and evolution (Day 4) and connect to the principle of "humans as a solution" from the course material.
3. Case Study Application (Accident Analysis): Apply the article's core framework
   to one of the major case studies from the course (e.g., Helios 522, Colgan Air 3407, British Airways 5390). Demonstrate in detail how the article's methodology or findings help explain the human factors contributions to that specific accident. Identify which elements of the accident chain the article's lens illuminates most effectively.
4. Case Study Application (Security Interface): Discuss the applicability of the article's focus (either CRM training or error classification systems) to aviation security contexts, as introduced on Day 4. Using the provided case study on cyber attacks targeting airport systems, analyze how human factors principles in your chosen article could be used to understand or reduce security-related errors or failures.
5. Systemic and Organizational Factors: Both safety and security depend on robust systems. Drawing on Day 5 (Application of Human Factors) content about Safety Management Systems (SMS), State Safety Programs (SSP), and organizational responsibilities, analyze how the insights from your chosen article should inform and be integrated into these wider systemic safety/security frameworks. Provide a practical example.
6. Critical Evaluation and Future Directions: Identify what you perceive to be the single most significant contribution of the article to the field of aviation human factors. Then, propose one specific, actionable recommendation for how the aviation industry (e.g., regulators like GCAA, airlines, training organizations) should update current practices based on this article's findings. Justify your recommendation by linking it to contemporary challenges discussed in the course.

Formatting for Part 1:

• Maximum 12 pages (A4, 12pt font, 1.5 line spacing).
• Include a title page with your details, chosen article, and word count.
• Number all pages.
• Use clear headings (e.g., "Question 1: Foundations and Frameworks").
• Integrate in-text citations in Harvard style for both the chosen article and relevant course concepts/case studies.
• A separate reference list for Part 1 is required at the end of this section. Part 2: Case Study Analysis and Policy Proposal Select one aviation accident where human factors significantly contributed to the
• outcome. Note: Originality in case selection is rewarded. Avoid overused cases unless you can provide genuinely novel analysis. Questions:

1. Briefly describe the selected accident's circumstances, clearly establishing why it is a relevant and significant case for human factors analysis. Justify your choice in terms of its learning value for the aviation industry.
2. SHELL Model Analysis
   Apply the SHELL Model comprehensively to your chosen accident. Analyze the interfaces and mismatches between
   1. Liveware (Human) and each component: Hardware, Software, Environment, and other Liveware.
   2. Identify the most critical mismatch that contributed to the accident chain. Support your analysis with specific evidence from the accident details.
   1. Summarize the key human factors findings from the official accident investigation.
      1. Evaluate one major change implemented by the industry in response to this accident (e.g., in training, technology, procedures, or regulation).
      2. Critically assess the effectiveness and limitations of this change in preventing similar future errors. Has it addressed the root causes or merely the symptoms?
   2. Preventive Policy Design
      Based on your analysis, propose one specific, actionable policy or procedural change aimed at reducing the effects of human factors. Your proposal should:
      1. Clearly target a latent condition or active failure identified in your SHELL analysis.
      2. Specify the responsible stakeholders (e.g., regulator, airline, manufacturer).
      3. Outline the intended implementation mechanism (e.g., updated CRM training module, revised checklist design, new monitoring requirement).
      4. d. Explain concisely how it would enhance system resilience. Formatting for Part 2:
         • Maximum 8 pages (A4, 12pt font, 1.5 line spacing).
         • Use the clear headings provided above (A, B, C and numbered questions).
         • Integrate in-text citations in Harvard style for accident reports, course materials, and supporting literature.
         • Include a separate reference list for Part 2 at the end of this section.
