Fundamental Concept in Aviation Safety
Asssignment Brief
Human Factors as a Fundamental Concept in Aviation Safety
- You are the Safety Team of a medium size international airline operating both long and short haul from a main operating base within the UK. A recent safety assurance report made comment that the airline does not have a Fatigue Risk Management System (FRMS).
- The lack of a FRMS concerns you and your team as decided to approach the airline board to convince them why the airline needs to adopt a FRMS.
- You are to prepare a 3000 word proposal that will be presented to the board to back up your presentation. The proposal must:
- Provide an overview of what a FRMS should include and the legal and regulatory responsibilities of the airline to manage the fatigue of its employees.
- Demonstrate the effects of fatigue on human performance and it’s influence on aviation safety.
- Critically analyse 2 examples of where fatigue has been a contributory factor to an aviation accident and how an effective FRMS could have prevented the accident.
- Critically evaluate methods of fatigue management that are employed by other airlines and provide an assessment of their effectiveness and how they work to manage fatigue.
- Propose 5 initiatives that the airline should introduce and include a critical assessment of the pros and cons of each proposal.
- Provide a couple of examples of emerging technologies that could be available in the near future to augment a FRMS.

Sample Answer
Proposal for the Implementation of a Fatigue Risk Management System (FRMS) at AeroGlide International Airlines
Executive Summary
This report is presented to the Board of Directors at AeroGlide International Airlines, a medium-sized international carrier operating from the UK. The absence of a Fatigue Risk Management System (FRMS) poses significant operational and safety risks. This proposal outlines the legal obligations, safety implications, and critical need for FRMS, drawing on real-world accident analysis, international best practices, and strategic initiatives that can be adopted immediately. The report concludes with actionable recommendations and explores emerging technologies that can enhance fatigue management.
Introduction to Fatigue Risk Management Systems
Fatigue Risk Management Systems (FRMS) are data-driven, adaptive processes that manage fatigue-related safety risks in complex operational environments. Rooted in safety management principles, an FRMS goes beyond regulatory compliance to proactively identify, assess, and mitigate fatigue hazards.
Key Components of an FRMS
-
Fatigue Reporting Systems – enabling confidential employee reporting.
-
Monitoring and Data Collection – using biometrics, actigraphy, and scheduling data.
-
Fatigue Risk Assessment Tools – scientific models to predict fatigue likelihood.
-
Training and Education – ensuring staff understand fatigue risks and mitigation.
-
Continuous Improvement Cycle – review, audit, and refine strategies.
Regulatory and Legal Responsibilities
The UK Civil Aviation Authority (CAA), following EASA regulations, mandates fatigue management via EU Regulation 965/2012, which specifies flight and duty time limitations. While compliance with these rules is mandatory, the regulation encourages airlines to adopt an FRMS for enhanced safety.
The International Civil Aviation Organization (ICAO) (Annex 6, Part I, Chapter 4.10) further supports FRMS implementation, defining it as a performance-based alternative to prescriptive duty limitations.
Effects of Fatigue on Human Performance and Aviation Safety
Fatigue is a physiological state of reduced mental or physical performance capability resulting from sleep loss, extended wakefulness, circadian phase, or workload (ICAO, 2011). In aviation, fatigue impairs cognitive functioning, decision-making, attention, and reaction time.
