Aircraft attitude is used to mean two closely related aspects of the situation of an aircraft in flight.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.
