x b axis - positive out the nose of the aircraft in the plane of symmetry of the aircraft; z b axis - perpendicular to the x b axis, in the plane of symmetry of the aircraft, positive below the aircraft; y b axis - perpendicular to the x b,z b-plane, positive determined by the right-hand rule (generally, positive out the right wing) Wind frame
The attitude indicator (AI), also known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth's horizon, and gives an immediate indication of the smallest orientation change. The miniature aircraft and horizon bar mimic the relationship of the aircraft relative to ...
An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw.These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [1] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers.
The vehicle's attitude must be controlled during powered atmospheric flight because of its effect on the aerodynamic and propulsive forces. [3] There are other reasons, unrelated to flight dynamics, for controlling the vehicle's attitude in non-powered flight (e.g., thermal control, solar power generation, communications, or astronomical ...
Changing orientation of a rigid body is the same as rotating the axes of a reference frame attached to it.. In geometry, the orientation, attitude, bearing, direction, or angular position of an object – such as a line, plane or rigid body – is part of the description of how it is placed in the space it occupies.

For aviators, proper recognition of aircraft attitude is most critical at night or in poor weather, when there is no visible horizon; in these conditions, aviators may determine aircraft attitude by reference to an attitude indicator. Spatial disorientation can occur in other situations where visibility is reduced, such as diving operations.
Nun Standing in Attitude of Prayer (1862), charcoal and pastel on paper, by François Bonvin Emma, Lady Hamilton made the striking of attitudes into an art form, portraying classical themes such as the Judgement of Paris. Attitude as a term of fine art refers to the posture or gesture given to a figure by a painter or sculptor. [1]
As the art critic Robert Hughes observed: "In Futurism, the eye is fixed and the object moves, but it is still the basic vocabulary of Cubism—fragmented and overlapping planes." [16] Futurist art tended to disdain traditional subjects, specifically those of photographically realistic portraits and landscapes. Futurists thought of "imitation ...
