Industry oriented university, research appeared in 1984, following the law on Higher education which provides that "engineering education [...] has a research activity, basic or applied, " and is organized around four areas: electronics, automation, computer and air transport economy. The university then feels interest for future engineers to learn research methods: while the method of deductive reasoning, for a long time favored by teachers in the two-years studies after French high school diploma and universities, shows its limitations, the method of inductive reasoning, characteristic of research, appears progressively better adapted to the nature of functions performed by today's engineers. The most recent manifestation of the growing interest in research at ENAC is the creation of the air transport economics laboratory, which designation reflects the desire to study, in addition to air transport itself, certain related activities such as air navigation.
