- Delayed or false sensation of the sensory organs.
- Lack of competence and experience.
What are some common human factors classification errors cited in accidents?
Drawing upon Reason’s (1990) concept of latent and active failures, HFACS describes human error at each of four levels of failure: 1) unsafe acts of operators (e.g., aircrew), 2) preconditions for unsafe acts, 3) unsafe supervision, and 4) organizational influences.
What is the single biggest contributor to crashes?
