Attention, Situational Awareness and Decisions
Attention and vigilance, perception, human reliability, situational awareness, risk assessment, time pressure and group influence.
How to prepare for the CAA GVC
Start with the current certificate and authorisation boundary, work through the five official subjects, then apply the material to mission planning, abnormal procedures and post-flight records with your approved RAE(PC).
Core concepts
Concept 1
Attention selects information while vigilance sustains monitoring; workload, fatigue, distraction and task design can degrade both.
Exam cue: State what has changed, what it means and what is likely to happen next.
Concept 2
Situational awareness requires perceiving relevant cues, understanding their meaning and anticipating how the operation is likely to develop.
Exam cue: Prioritise aircraft control, airspace and people before secondary mission tasks.
Concept 3
Risk decisions are shaped by experience, commitment, time pressure and other people, so predefined limits and active challenge protect against continuation bias and risk shift.
Exam cue: Invite and act on a crew member's safety concern without waiting for proof of failure.
Risk pitfalls and guardrails
Confusing high workload with effective monitoring.
Guardrail: Do not treat a GVC, provider procedure, automation feature or Operational Authorisation maximum as permission to ignore current airspace, aircraft, weather, people or operator-specific conditions.
Continuing because time and money have already been invested.
Guardrail: Do not treat a GVC, provider procedure, automation feature or Operational Authorisation maximum as permission to ignore current airspace, aircraft, weather, people or operator-specific conditions.
Allowing group confidence to replace an evidence-based risk assessment.
Guardrail: Do not treat a GVC, provider procedure, automation feature or Operational Authorisation maximum as permission to ignore current airspace, aircraft, weather, people or operator-specific conditions.
Memory anchors
Attention
Attention selects limited information for current processing.
Vigilance
Vigilance sustains detection over time and degrades with fatigue and monotony.
Awareness
Perceive, understand and project the state of the operation.
Reliability
Human performance varies with person, task, environment and organisation.
Time Pressure
Time pressure can narrow options and encourage continuation beyond a safe limit.
Risk Shift
Group influence can push a decision toward greater or lesser risk; use agreed criteria.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
