Human Factors

Welcome to CAA Human Factors

Welcome to the CAA Human Factors portal

Human Factors (HF) and our understanding of its effects on safety performance continue to evolve and develop.

In order to reduce HF risks in aviation safety we must influence attitudes and behaviours while embedding HF thinking into everything we do.

By taking this approach we aim to improve aviation safety and keep the interest of the consumer at the heart of our work. 

Human Factors Strategy

We are pleased to announce the release of our strategy for Human Factors in civil aviation and the supporting action plan. The strategy sets out our aims and objectives to improve HF awareness as part of our move towards performance based oversight.
