Since 2002, ECAC has been organising multilateral workshops in the areas of safety, security, facilitation and the environment in order to update its Member States on the latest regulatory or technical developments, or to address common deficiencies. Subject areas are selected following requests from Member States, after identification of areas of concern within an ECAC expert group.
ECAC and the European Commission work in close cooperation on all aspects of European air transport. In 1995, they agreed that it would be worthwhile to periodically bring together leaders of the air transport industry – representing scheduled, non-scheduled and regional airlines as well as airport management – with the Directors General of ECAC's Member States.
The annual ECAC Forum was established in 2008 to give the Directors General of Civil Aviation of ECAC's forty-four Member States the opportunity for an open discussion of strategic issues with potentially far-reaching national and international significance. The one-day Forum is held back-to-back with the December Directors General meeting in Paris.
ECAC meets in Plenary (Triennial) Session once every three years at the European Parliament in Strasbourg, the birthplace of ECAC. The duration of the meeting is one and a half days and it is typically held in June or July. The most recent Triennial Session - the thirty-ninth - was held on 12 July 2021 and exceptionally was a one-day virtual event.
