Complacency: the degradation of vigilance in a situation.
Crew resource management: team-based Human Factors training for flight crews.
Human Factors: the scientific study of the interaction between people, machines and each other.
Human Factors principles: principles which apply to aeronautical design, certification, training, operations and maintenance and which seek safe interface between the
human and other system components by proper consideration to human performance.
Human performance: human capabilities and limitations which have an impact on the safety and efficiency of aeronautical operations.
Instructional systems design: a generic term for the methodology of creating and implementing a training programme.
Inter-team: occurring between separate teams.
Intra-team: occurring within a team.
Latent failure: a type of human error whose effects may lie dormant until triggered later, usually by other mitigating factors.
