m) Confidential Aviation Hazard Reporting System (CAHRS) Compared to the previous financial year, there has been a 10% decrease in the number of CAHRS reports that have been recorded as depicted in the graph below.

Safety promotions would be earmarked for Serious Incidents due to under-reporting, in the main we ought to keep the positiveness in this regard.

The AIID meets yearly with the International Confidential Aviation Safety Systems (ICASS) group that promotes the confidential reporting systems method as one avenue to improve flight safety in commercial air transport and general aviation operations. The ICASS group’s main goals are as follows: • To facilitate the exchange of safety-related information between independent confidential aviation reporting systems. • To identify solutions to common problems in the operation of such systems.
