Human factors evidence has been incorporated into large aircraft operations since the 1970's and is now regarded as part of standard procedure. Airline transport data indicate that air travel remains the safest form of transport. However there are two tiers of flight operations, large and small aircraft, and there may be some important differences between these two groups, and also within the small aircraft sector itself. This paper is an overview of data collected from 426 Australian small aircraft pilots in September-October 2008. Pilots were asked about knowledge, beliefs and actions regarding incoming human factors based regulations. Differences in pilot responses are evaluated and implications for introducing and supporting operational changes are considered.
