Abstract. The security of civil aviation is regulated by a series of international standards and recommended practices. The EDEMOI project aims at investigating different techniques to analyse these standards. In this paper, we address two automated analysis techniques. First statetransition diagrams are extracted to visualize the nominal behavior of the involved actors. Then, models are lightly altered, and test scenarios are generated to determine how security measures could be breaked. Keywords. Civil aviation standards, security, modelling, formal methods, test generation.
