- 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…

acceleration forces overpowering gravity. [Figure 17-6] These situations include uncoordinated turns, climbing turns, and turbulence. 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 if there is no sensation during any of these maneuvers, the absence of sensation is still an effective demonstration because it illustrates the inability…

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…

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…

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. Coping with Spatial Disorientation To prevent illusions and their potentially disastrous consequences, pilots can: 1. Understand…
