  Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Upset Prevention and Recovery › Spatial Disorientation

  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…

  Chapter 17: Aeromedical Factors › Treatment of Hypoxia › Spatial Disorientation and Illusions

  Spatial Disorientation and Illusions Spatial disorientation specifically refers to the lack of orientation with regard to the position, attitude, or movement of the airplane in space. The body uses three integrated systems that work together to ascertain orientation and movement ... moving. Flying can sometimes cause these systems to supply conflicting information to the brain, which can lead to disorientation. During flight in visual meteorological conditions (VMC), the eyes are the major orientation source and usually prevail over false sensations from…

  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…

  Chapter 3: Human Factors › Demonstration of Spatial Disorientation

  Demonstration of Spatial Disorientation There are a number of controlled aircraft maneuvers a pilot can perform to experiment with spatial disorientation. While each maneuver normally creates a specific illusion, any false sensation is an effective demonstration of disorientation. Thus, even ... demonstrating these various maneuvers. 1. 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 lessen the occurrence…

The discussion of disorientation in Chapter 3, Human Factors, indicates the importance of trusting the instruments. 5. Failure to practice basic instrument skills ... confidence necessary for use of flight instruments during departures under conditions of low visibility, rain, low ceilings, or disorientation at night. A sudden rapid transition from “visual” to “instrument” flight can result in serious disorientation and control problems. Instrument takeoff…

  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 ... then tells the pilot to look up and recover. The benefit of this exercise is the pilot experiences the disorientation while flying the aircraft.
