Orientation and Control Surfaces
•The three critical flight dynamic parameters are the angles of rotation in three dimensions about the vehicle's center of mass, known as roll, pitch and yaw.

•While in a gaseous atmosphere, the most common orientation controls comes in the form of control surfaces like control fins, elevators, rudders, ailerons and flaps. •Rockets also use complex and sensitive Gyros, gimbaling systems, thrust vectoring (like on the F-22 Raptor built at Lockheed), reactionary control wheels, Reactionary Control Thrusters and other devices for control outside the presence of an atmosphere to operate in the complete vacuum of space.
