Spatial orientation (the inverse being spatial disorientation, aka spatial-d) is the ability to maintain body orientation and posture in relation to the surrounding environment (physical space) at rest and during motion. Spatial disorientation, spatial unawareness is the inability of a person to correctly determine his/her body position in space this phenomenon refers especially to aircraft pilots and underwater divers, but also can be induced in normal conditions—chemically or physically (eg, by blindfolding) in aviation, the term means the inability to correctly interpret aircraft attitude, altitude or.

A sensory illusion is a false perception of reality caused by the conflict of orientation information derived from one or more equilibrium mechanisms. Spatial disorientation, spatial unawareness, or 'spatial-d' is the inability to determine one’s position, location, and motion relative to their environment this phenomenon most commonly affects aircraft pilots and underwater divers, but also can be induced in normal conditions—or reproduced in the lab with instruments such as the barany chair. Objective: the aim of this study was to test the effects of visual and vestibular spatial disorientation on the cognitive performance of military aviators while they were piloting a flight simulator.

Once an aircraft enters conditions under which the pilot cannot see a distinct visual horizon, the drift in the inner ear continues uncorrected errors in the perceived rate of turn about any axis can build up at a rate of 02 to 03 degrees per second if the pilot is not proficient in the use of. Pathology – spatial disorientation (spatial-d) in order to fully understand spatial disorientation, it is important to note how these sensory systems work together to determine the body’s relative motion and orientation.
