The movement about an axis that
is perpendicular to the vehicle's longitudinal axis and horizontal with
respect to a primary body. Pitch attitude is the orientation
of an aircraft or spacecraft with respect to the pitch axis. The pitching
moment is the rising and falling of the vehicle's nose. When the
nose rises, the pitching moment is positive; when the nose drops, the pitching
moment is negative and is also called a diving moment.
Compare with roll and yaw.
