"Last days to have your say on CASA’s performance
The important new survey being conducted to benchmark the aviation community’s views about CASA closes on 18 December 2015. The online survey takes about 15 minutes to complete and covers CASA’s key performance areas. Views are sought on CASA’s performance in specific areas such as efficiency, responsiveness, accountability and timeliness. Questions cover how easy it is to comply with regulations, the development of new regulations, consistency of decision making and satisfaction with service delivery. Overall, the survey aims to determine the strengths and weaknesses of CASA’s relationship with the aviation community. Results will be used by CASA’s Board and management to improve CASA’s performance, build stronger working connections with the aviation community and lift service delivery. The survey is being conducted online by an independent market research organisation, all responses are held securely and participants can choose to be anonymous. This survey will be run every two years so CASA can measure changes in performance and interaction with the aviation community. The survey meets recommendation eight of the Aviation Safety Regulation Review.
