1. According to Reason's Swiss Cheese Model, what is the difference between an active failure and a
latent failure?
Active failures are unsafe acts committed by front-line personnel (e.g., engineers, pilots) that have
immediate adverse consequences. Latent failures are dormant decisions or conditions made by
management or designers that may lie hidden for a long time before combining with other factors to
breach defences.
Rationale: Reason's model distinguishes between the immediate errors of operators and the
systemic, organisational weaknesses that create the conditions for those errors to become
catastrophic .
2. What is "environmental capture" in the context of aircraft maintenance human factors?
It occurs when an engineer carries out a familiar task in a specific location out of habit, even when
that task is not required for the aircraft currently being worked on.
Rationale: Environmental capture is a type of action slip where the physical setting triggers a
habitual routine, overriding conscious decision-making .
3. Define "reversion" as a human error mechanism.
Reversion occurs when a person abandons a recently revised procedure and unconsciously reverts
to a long-established pattern of behaviour, particularly under stress or low concentration.
Rationale: Old habits are deeply ingrained and difficult to unlearn; when cognitive resources are
stretched, the brain defaults to the older, more practised routine .
4. What is the typical capacity and duration of working memory?
Working memory typically holds approximately 7 (±2) chunks of information for a duration of
roughly 30 seconds before the data is lost unless rehearsed.
,Rationale: Understanding these limits is crucial for designing checklists and radio communication
procedures to prevent data loss .
5. Explain the concept of "chunking" in memory.
Chunking is a technique of grouping individual pieces of information into larger, meaningful blocks
(e.g., grouping digits into a phone number format) to increase the amount of data held in working
memory.
Rationale: By grouping data, the effective capacity of working memory is expanded, aiding in tasks
like recalling complex clearances or checklists .
6. What is "confirmation bias" at the knowledge-based level of performance?
Confirmation bias is the tendency for a person to seek out and interpret information that confirms
their initial hypothesis (e.g., a diagnosis of a fault) while ignoring or discounting evidence that
contradicts it.
Rationale: At the knowledge-based level, where situations are novel, this bias can lead an engineer
or pilot to persist with an incorrect solution .
7. What phenomenon is described as "diffusion of responsibility" in a team setting?
It is the psychological phenomenon where individuals in a group feel less personally responsible for
taking action because they assume another group member will do it.
Rationale: This can lead to critical tasks being missed during maintenance or pre-flight checks if
responsibilities are not explicitly assigned .
8. Distinguish between semantic memory and episodic memory.
Semantic memory is the database of facts, concepts, and rules (e.g., checklist procedures). Episodic
memory is the recollection of specific personal events and experiences (e.g., remembering a
particular flight where an emergency occurred).
Rationale: Both types are essential for pilots and engineers, with semantic memory used for routine
procedures and episodic memory aiding in recalling lessons from specific past experiences .
9. What is "over-learning" and why is it important in aviation training?
Over-learning is the practice of repeating a task or procedure far beyond the point of initial
proficiency. It is important because it creates strong, automatic recall that is resistant to decay and
can be retrieved under high-stress emergency situations.
Rationale: High-stress environments degrade cognitive performance; over-learned responses (like
emergency drills) become reflexive, reducing the chance of error .
, 10. What is the "Controller Blind Spot" phenomenon?
It refers to a situation where an air traffic controller fails to detect a conflicting aircraft that is often
located directly within their field of view, due to limitations in human visual perception and
attention.
Rationale: This is a recognised human performance issue that requires mitigation through
technology and procedural cross-checks, as the eye alone is not always reliable .
11. In the context of mental health in aviation, what is the focus of the MESAFE project's
recommendations?
The recommendations focus on shifting terminology and assessment from "mental disorders" to
"mental incapacitation events," implementing risk assessment approaches, and fostering
multidisciplinary collaboration (AMOS) for aeromedical decisions.
Rationale: The Germanwings accident highlighted the need for a system that assesses the
operational risk of a mental health condition leading to incapacitation, rather than just the diagnosis
itself .
12. What is a "mnemonic" and how does it relate to long-term memory?
A mnemonic is a memory aid (e.g., an acronym or phrase) that helps encode and retrieve
information from long-term memory by associating it with a familiar or easily remembered
structure.
Rationale: Mnemonics provide a structured "hook" for retrieving rarely used but critical information,
such as emergency checklists .
13. How does "peer pressure" negatively affect safety in a maintenance team?
Peer pressure can cause an individual to ignore their own concerns or safety instincts to conform to
the group's behaviour or to avoid delaying the team's progress, potentially leading to the acceptance
of unsafe practices.
Rationale: The desire to fit in or not be seen as a "troublemaker" can override professional
judgement, a key factor in group dynamics .
14. What is the "knowledge-based" level of performance according to Rasmussen's SRK framework?
It is the highest cognitive level, used in unfamiliar or novel situations where the person has no pre-
existing rules or skills to apply, requiring conscious analysis and problem-solving.
Rationale: This level is the most cognitively demanding and prone to error due to incomplete
knowledge or misinterpretation of the situation .
