PREVENTION OF SPATIAL DISORIENTATION
There is no such thing as total prevention of spatial disorientation.
However, the best prevention is understanding that the misleading sensations
which come from our sensory apparatus are predictable. They can happen to
anyone since they are due to the normal functions and limitations of our
sense of balance. Awareness of this potential hazard means that the pilot
who experiences these sensations must understand their significance and how
to overcome them.
a. Reference Points. Never fly without visual reference points.
These
can be either a visual horizon or an artificial horizon provided by
instruments.
b. Instruments.
Trust your instruments.
c. Lights.
Never stare at lights.
d. Conditions to Avoid. Avoid fatigue, smoking, hypoglycemia
(deficiency of sugar in the blood), hypoxia and anxiety. These conditions
ill aggravate all illusions.
