The European Commission produces annual reports as part of its function as an observatory of the European Air Transport Industry. The reports highlight developments on legislative and regulatory measures and cover analyses of capacity, traffic and financial performance of airlines and airports, as well as include topics such as air traffic control, environment, consumer issues and aircraft manufacturing.
Beside the annual reports, a vademecum was also published for each quarter until Q2/2008. These "quarterly reports" take stock of the highlights and developments of the period and within each issue analyse in more detail one subject related to the industry.
Topical reports (currently produced instead of quarterly reports) provide more in-depth view on topics related to air transport industry.
