Pilots are more subject to spatial disorientation if

• A. They ignore the sensations of muscles and inner ear
• B. They rely on such sensations
• C. They use only instruments
• D. They watch for color changes

Answer: (A)

Spatial disorientation happens when what your body senses conflicts with what the aircraft is actually doing or what your instruments show. The inner ear and muscles can produce convincing sensations of motion even when there isn’t corresponding attitude or bank, especially in poor visibility. If you ignore those bodily sensations, you remove a valuable cross-check that could alert you to a mismatch between sensation and reality. In conditions with limited outside references, that lack of cross-check makes misinterpretations of attitude more likely, increasing the chance of becoming disoriented. So trusting and cross-checking the instruments and available references, rather than relying on misleading bodily cues, is the safer approach.
