The CAA uses several safety data sources to monitor risks. The best known of these is the Mandatory Occurrence Reporting Scheme (MORS). Under this scheme, all safety hazards or potential hazards involving UK registered aircraft or aircraft in UK airspace are required to be reported to the CAA’s Safety Investigation and Data Department. These reports provide an invaluable source of safety information which can be used by  specialist surveyors and, for further analysis, by the Strategic Safety and Analysis Unit.

Other information sources are also used to assess risk across the whole aviation system. These can be world-wide accident and serious incident reports, information from the UK Operational Flight Data Monitoring programmes and data from special safety studies, all supported by comprehensive operational data.

To help the CAA in its task, as well as providing industry, academia and the public at large with safety information, we published an Aviation Safety Review, 1992 – 2001. This document, CAP 735, is accessible on this website and is a comprehensive source of safety information for all aspects of aviation. We hope this information is of value and welcome any comments (see Introduction to CAP 735 for details).

Finally, the big challenge for the industry as aviation continues to grow in the future is to identify ways to improve safety. This challenge can only be met by better understanding the past so we can better predict the future. This is no easy task and new business practices are being developed to ensure this is achieved as effectively as possible.
