Pilots are more subject to spatial disorientation if
A
they ignore the sensations of muscles and inner ear.
B
visual cues are taken away, as they are in instument meteorological conditions (IMC).✓ Correct Answer
C
eyes are moved often in the process of cross-checking the flight instruments.
Explanation
PHAK Chapter 17 explains that orientation depends mainly on vision; when visual references are removed, as in IMC, the pilot relies on the inner ear and body sensations, which can give false signals and lead to spatial disorientation. Ignoring those sensations and trusting the instruments is the defense, and a regular instrument cross-check is the correct technique, not a cause.
