1. The development of global strategies contained in the Global Aviation Safety Plan and the Global Air Navigation Plan;
2. The development and maintenance of Standards, Recommended Practices and Procedures applicable to international civil aviation activities which are contained in 16 Annexes and 4 PANS (Procedures for Air Navigation Services).  These standards are complemented by more than 50 Manuals and Circulars which are providing guidance on their implementation.
3. The monitoring of safety trends and indicators.  ICAO audits the implementation of its Standard, Recommended Practices and Procedures through its Universal Safety Oversight Audit Programme.  It has also developed sophisticated tools to collects and analyse a vast array of safety data which allows to identify existing and emerging risks   
4. The implementation of targeted safety programmes to address safety and infrastructure deficiencies; and
5. An effective response to disruption of the aviation system created by natural disasters, conflicts or other causes.

In all of its highly coordinated safety activities, ICAO strives to implement practical and achievable measures to improve safety and efficiency in all sectors of the air transportation system. This approach ensures that aviation’s complimentary achievements of a remarkably safe and efficient air transport network continue to serve a fundamental role in supporting global social and economic priorities.
