Objectives
Flight Mechanics I introduces students to aircraft performance. It includes the general equation of motion of aircraft and the analysis of the flight in cruise conditions, climbing and descent maneuvers in the vertical plane, coordinated turn, takeoff and landing. The course also discusses some basic concepts on stability and control like the neutral point. It makes emphasis on the mathematical models and analysis techniques of this engineering branch, simulation of the aircraft motion, and evaluation of flying qualities, with brief discussion on regulations, guidance, navigation, and control.
