Center of Gravity Center of Gravity (CG) is point where weight of object is balanced Centroid located on the line of symmetry Centroid of object with multiple lines of symmetry is located at intersection of lines of symmetry
Stability Aircraft with positive stability returns to steady flight after disturbance Maneuverability is an indication of an aircraft’s ability to handle the stress of maneuvers Controllability is an indication of an aircraft’s ability to react to pilot inputs
Aircraft Attitude Aircraft have three axes of flight which intersect at the center of gravity Aircraft must be stable around these three axes for controlled flight Aircraft must be controlled to rotate around these three axes to change direction Longitudinal Axis Lateral Axis Vertical Axis Center of Pressure Center of Gravity

Aircraft Roll Stability and Control To turn left, the aircraft must roll left. Right wing must raise and left wing must descend. Right aileron is lowered and left aileron is raised. Longitudinal Axis
Flight Controls that Cause Ailerons and Flaps to Move Yoke rotated left Left wing shown Left aileron raises Right aileron lowers Left and right flaps lower Flaps lever lowered
Aircraft Pitch Stability and Control Lateral Axis Pitch Down Push the yoke forward To descend, the pilot reduces power and lowers the elevator to pitch down Lower the elevator
