PACDEFF is the largest CRM, NTS and Aviation Human Factors Conference of its type in the world, with around 300 attendees generally attending pre-COVID. The forum is intended as a non-profit, non-partisan opportunity for Human Factors practitioners to meet and discuss contemporary issues in the Human Factors field, with an emphasis on airline training.

In 2023 PACDEFF will be bringing you a conference which offers a substantial array of CRM, NTS, Aviation Human Factors, and Aviation Psychology topics, which will be of interest to a wide cross-section of Human Factors, Aviation Psychology and Safety professionals, practitioners and academics.

PACDEFF 2023 Call for Speakers

12 and 13 September 2023 – Rydges Hotel South Bank, Brisbane

We encourage a wide and diverse range of topics which will be of interest to our varied audience, who are largely involved in Aviation Human Factors. We also welcome speakers from outside of aviation, who can provide delegates with interesting and relevant topics, particularly where Human Factors challenges are shared across domains and industries.
