States have implemented actions that may include temporary changes to national regulations, or 'alleviations', necessary to maintain aviation operations during the COVID-19 pandemic. These alleviations refer to temporary differences as provided in Article 38 of the Chicago Convention, and temporary exemptions and exceptions as described in the Safety Oversight Manual (Doc 9734).

Note on cumulative risks associated with multiple alleviations: Where multiple alleviations are used simultaneously by a service provider or operator, particular attention must be given to how any associated cumulative risks are addressed. In some cases, a State may deem it necessary to limit the number or extent of alleviations to be used.

This section of the web site provides guidance for States to establish such temporary alleviations.
