Pitch

Pitch is 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.

 

 

Roll

Roll is the motion of an aircraft or spacecraft about its longitudinal, or nose-tail, axis.

 

Yaw

Yaw is the lateral rotational or oscillatory movement of a vehicle about its vertical axis. The amount of movement is measured in degrees.
