AeroMed Flashcards
Define Spacial Disorientation
a pilot’s erroneous perception of position, attitude, or motion in relation to the gravitational vertical and the Earth’s surface
Define Orientation illusion
a false perception of position or motion caused by discordant or erroneous sensory orientation information
Spatial Orientation
a pilot’s correct perception, integration, and interpretation of aircraft position, attitude, and motion with respect to the gravitational vertical and the earth’s surface
Types of Spatial Disorientation
Type I Unrecognized
Type II Recognized
Type III Incapacitating
Type I most dangerous
What are the systems of Orientation Maintenance
Visual, vestibular, auditory, and somatosensory systems
Define the Visual System
the most important
provides position and motion cues to orient the human within the perceived environment
Define Vestibular system
consists of the semicircular canals and vestibule proper
Organs sense changes in motion and aircraft attitude
semicircular canals sense angular acceleration (yaw, roll, pitch)
Otoliths (vestibule proper) sense linear acceleration (acceleration /deceleration)
Define Somatosensory System
reacts to tactile and kinesthetic sensations resulting from forces or pressure on sensors in the skin, joints, tendons, or muscles and position of internal organs.
Interprets sensory signals through expectation
What can cause Spacial Disorientation
Operational Illusions Spatial Operation Operational Environment Situational Awareness Degraded Visual Environment Workload/Task Saturated Visual Cues
In the event of suspected or recognized SD reference _______ with a good _______ and attempt to ________
In the event of suspected or recognized SD reference instruments with a good cross check and attempt to transfer flight controls
