Types of Fatigue
ACM
Acute fatigue symptoms
Inattention
Distractibility
Errors in Timing
Neglect of Secondary Tasks
Loss of Accuracy and Control
Lack of Awareness or Error Accumulation
Irritability
These signs/symptoms will be apparent to the rest of
the crew before the individual realizes them.
Chronic fatigue symptoms
Insomnia
Depressed Mood
irritability
Weight Loss
Poor Judgment
Loss of Appetite
Slowed Reaction Time
Poor Motivation and Performance at Job
MOTIVATIONAL EXHAUSTION (BURNOUT)
If chronic fatigue is allowed to continue untreated for too long, the individual will eventually “shut down” and cease functioning occupationally and socially.
Spatial D types
URI (type 1-3)
TYPE I UNRECOGNIZED
Most Dangerous The aviator does not perceive any indication of spatial disorientation. What is seen or thought to be seen , is corroborated by the senses. An example of this is the Height-Depth Perception Illusion.
TYPE II RECOGNIZED
The problem is perceived but not
recognized. The aviator may feel that flight controls are malfunctioning or that there is a failure of the instruments. The classic example is the Graveyard Spin.
TYPE III INCAPACITATING
The aviator experiences such an
overwhelming sensation of movement that they cannot orient visually or by instruments. This disorientation isn’t fatal if control of the aircraft is regained. An example of this is the Coriolis Illusion.
OTHER SPATIAL DISORIENTATION TERMS
SENSORY ILLUSION- False perception of reality caused by the conflict of orientation information from one or more mechanisms of equilibrium. This is the major cause of spatial disorientation.
VERTIGO- Spinning sensation usually
caused by a peripheral vestibular
abnormality in the middle ear. Often
misused term that crewmembers apply to all forms of spatial disorientation or dizziness.

PROPRIOCEPTIVE SYSTEM ILLUSIONS
PROPRIOCEPTIVE ILLUSIONS- Very rare and normally don’t occur alone. Usually associated with the Vestibular system and to a lesser degree the Visual system. Normally this illusion is felt as a false sense of vertical speed. During a turn when there is no visual reference, a proper turn gives a pushing feeling in the seat and pilot perceives vertical climb. The opposite is true in turn recovery where pressure into the seat is lifted. Pilot may perceive a descent and climb or reduce airspeed.
