Commercial aviation safety is the best it has ever been,

and flight operations are effectively and efficiently

moving forward. While recognising the many successes in

aviation, there are increasing expectations of safety, new

technologies, new airspace operations, new generations of

aviation professionals and other factors that are changing

aviation. There are both challenges and opportunities in

these changes, and fundamental questions to be answered.

This lecture will discuss those challenges and opportunities,

and identify fundamental underlying questions.
