Accidents due to Spatial Disorientation (SD), in military and general aviation, reportedly vary between 2.1 to 31% [1 – 11]. Despite of physiological limitations of the ‘human’ operator, accident statistics do not correctly reflect SD as a cause, as commonly as expected, especially in the military aviation. In fact, in a review of accidents due …

Orientation & Pilot Training – Likely Lacunae!
James Doolittle made history on 24 September 1929, when he took off, flew a distance of 20 miles and landed an airplane by instruments alone . The array of instruments included the Sperry Horizon, precursor of the artificial horizon, which still remains the essential instrument for maintaining orientation in flight.
Spatial Disorientation – Vestibular Illusions
The vestibular illusions are divided as per the affected sub-system viz. otolith organ or semicircular canals. Though there are many an illusions, only the common vestibular illusions have been briefly discussed.
Spatial Disorientation – Visual Illusions
Various visual illusions are enumerated here. Though there are many an illusions, only the common visual illusions have been briefly discussed.
Spatial Disorientation: Prevention
Prevention of SD is a multi-pronged approach. Preventive strategies start with the selection of healthy candidates with normal vestibular function for aviation duties. The trained aircrew should make conscious and concerted efforts to be physically and mentally healthy, and if unwell or under medication – prescribed or self-medicated, must avoid flying under any circumstances for their …
