In addition, whilst the ability to learn from an accident is crucial, purely reactive systems have been found to be of limited use in continuing to bring forward improvements. Reactive systems should therefore be complemented by proactive systems which use other types of safety information to make effective improvements in aviation safety. The Union, its Member States, the European Aviation Safety Agency (‘the Agency’) and organisations should contribute to the improvement of aviation safety through the introduction of more proactive and evidence based safety systems which focus on accident prevention based on the analysis of all relevant safety information, including information on civil aviation occurrences.
