Learning outcomes

Starting from the main results of aircraft subsonic aerodynamics, fundamental problems of jet and propeller aircraft performance are carried out within classical flight conditions (steady level flight, climb, gliding, and steady turn). Longitudinal, lateral and directional static stability and controllability are also addressed.
