  Chapter 17: Aeromedical Factors › Diving or Rolling Beyond the Vertical Plane › Coping with Spatial Disorientation

  Coping with Spatial Disorientation To prevent illusions and their potentially disastrous consequences, pilots can: 1. Understand the causes of these illusions and remain constantly alert for them. Take the opportunity to experience spatial disorientation illusions in a device, such ... Barany chair, a Vertigon, or a Virtual Reality Spatial Disorientation Demonstrator. 2. Always obtain and understand preflight weather briefings. 3. Before flying in marginal visibility (less than 3 miles) or where a visible horizon is not evident, such as flight…

  Spatial Disorientation Spatial disorientation has been a significant factor in many airplane upset accidents. Accident data from 2008 to 2013 shows nearly 200 accidents associated with spatial disorientation with more than 70% of those being fatal. All pilots are susceptible ... airplane to divert from the desired flightpath because they cannot resolve the conflict. A pilot may experience spatial disorientation or perceive the situation in one of three ways: 1. Recognized spatial disorientation: the pilot recognizes the developing upset…

  Illusions in Flight a. Introduction. Many different illusions can be experienced in flight. Some can lead to spatial disorientation. Others can lead to landing errors. Illusions rank among the most common factors cited as contributing to fatal aircraft accidents ... Illusions Leading to Spatial Disorientation. 1. Various complex motions and forces and certain visual scenes encountered in flight can create illusions of motion and position. Spatial disorientation from these illusions can be prevented only by visual reference to reliable, fixed…

  Diving or Rolling Beyond the Vertical Plane This maneuver may produce extreme disorientation. While in straight-and-level flight, the pilot should sit normally, either with eyes closed or gaze lowered to the floor. The instructor pilot starts a positive ... time the maneuver so the roll is stopped as the pilot returns his or her head upright. An intense disorientation is usually produced by this maneuver, and the pilot experiences the sensation of falling downward into the direction…

  They teach pilots to understand the susceptibility of the human system to spatial disorientation. 2. They demonstrate that judgments of aircraft attitude based on bodily sensations are frequently false. 3. They help decrease the occurrence and degree of disorientation through ... better understanding of the relationship between aircraft motion, head movements, and resulting disorientation. 4. They help instill a greater confidence in relying on flight instruments for assessing true aircraft attitude. A pilot should not attempt any of these maneuvers…
