The international dimension of the university grew in the 1990s. It is constrained, however, by the design and implementation of the new cycle for air traffic controllers. The effort required a specifically European component. It consists first in the participation in European projects such as EATCHIP (European Air Traffic control Harmonization and Integration Program), then in joining mobility programs for students such as Erasmus or Socrates. Under these programs, the university welcomes a growing number of foreign students. In doing so, it forges close relations with foreign universities, including those of Berlin and Darmstadt in Germany, as well as the one of Tampere in Finland. Since 1990, the university has new missions. Thus, ENAC negotiates new contracts for studies and research abroad. The 2000s are the years of the creation of courses entirely taught in English language and the development of activities focused on air navigation. In 2009, the university and its alumni association organize the first edition of the "salon du livre aéronautique" (aeronautical literary festival) in Toulouse. In December 2010, ENAC becomes an ICAO center for training in aviation security.
