Earl began his career in aviation in 1988 with the Royal Australian Air Force, graduating from pilot training in 1992. He flew with a transport squadron for more than three years before returning to the Flying School at RAAF Pearce to take up a post as a flying instructor. As a flying instructor, his key role was developing young RAAF officers into military pilots, and he delivered instruction in aerodynamics, aviation medicine and various aircraft systems.
After 12 years with the RAAF, Earl joined BAE Systems and - following a short stint of flying in the UK - moved to the Middle East where he provided flight training to the Saudi Air Force as part of a multi-national team of experienced flying instructors from a number of western air forces. In 2010, he returned to Australia having accrued 4000 flying hours, of which more than 1500 were instructional.
In addition to a flying career, Earl has developed and managed two small businesses and worked as a training consultant developing and delivering a variety of short courses, and facilitating nationally-recognised diploma and certificate IV programs across Australia. He worked with Boeing Defence Australia where he was involved in the design and coordination of flight crew training as part of the RAAF, Korean and Turkish AEW&C acquisition projects.
Earl has degrees in computer science and a Master of Human Resources and Organisational Development.
He joined CASA in June 2012 as an aviation safety advisor. Given the pace of change in both the regulatory and technological environment, he strongly believes ongoing education is increasingly critical as the basis of a healthy safety culture both within organisations and among the many individuals involved in the field of aviation.
