ICAO: Frequently Asked Questions

What does ICAO audit?


ICAO audits the aviation safety and aviation security oversight capacities of its 193 Member States. In the Safety domain these are carried out under our Universal Safety Oversight Audit Programme (USOAP), while in the security domain we operate a similar Universal Security Audit Programme (USAP).


It is important to recognize that these audits do not cover airlines, airports or other industry operators. Rather they are restricted to only the legislation, resources and other capacities which State governments establish in order to effectively implement ICAO’s Standards and Recommended Practices (SARPs) in each area.


Aggregated USOAP results may be reviewed interactively by the public on ICAO’s website. Security audit results are confidential and are not made public. They are, however, shared with other Member States through suitably confidential mechanisms.


If you have further questions about the USOAP, please consult the USOAP FAQ.
