List of possible attitudes
In the simplest use it is the orientation of an aircraft with respect to the horizon. This is a function of two angles: pitch and roll. The pitch angle specifies the orientation of the aircraft's longitudinal axis, that is, whether the nose is pointing upwards, is level to the horizon, or is pointing downwards. The roll angle specifies whether the aircraft is banked left or right, or whether its wings are parallel to the horizon. The pilot adjusts the controls (the stick or the yoke) to adjust the aircraft attitude in order to keep the aircraft on course or turn or change altitude.
Aircraft attitude is used to describe the more complex relation of an aircraft to its surroundings, particularly airflow and gravity. This takes into account the settings of other flight control surfaces such as the rudder, engine power, flaps or slats and also airflow. Thus an aircraft can be described as being in a climb attitude or a spin attitude, which implies more than simply nose up or nose down.

Attitude dynamics and control
The attitude of a body is its orientation as perceived in a certain frame of reference; providing a vector along which a spacecraft is pointing is a description of its attitude.
Dynamics is the term for the modeling of changing conditions, due to external forces acting on the body.
Control is the purposeful, designed manipulation of those external forces to determine the craft's attitude. Dynamic response is guaranteed in any natural setting, ergo control is essential to useful application of aerospace craft, as any use of said craft involves moving something from a specific somewhere to another specific somewhere else, as efficiently as possible.
