Learning outcomes
At the end of the module, the student knows the fundamentals of aircraft static stability, controllability and maneuverability. In particular he learns the analytical tools to deal with problems related to longitudinal and lateral-directional preliminary design and performance analysis. The acquired knowledge also allows the student to address aircraft trim and loading problems.
