DEFINITION:

Although many other examples of international co-operation in the different aviation fields can be mentioned, the most important one is the safety co-operation: as European Agency EASA states: “As globalisation advances, aviation safety is increasingly a cooperative, global effort.  EASA partners with civil aviation authorities, regional and international organisations alike, in order to enhance aviation safety worldwide, support the free movement of European products and services and promote European and global safety standards”.
