← HistoryWhich consequence results when hygrometer precision degrades within a navigational sextant?
A)Increased magnetic declination error
B)Unreliable celestial altitude measurements
C)Elevated atmospheric refraction calculations✓
D)Compromised structural integrity overall
💡 Explanation
Elevated atmospheric refraction calculations occur because the hygrometer errors increase uncertainty in air density which influences light bending when using the sextant. Therefore, observed altitude angles are incorrect rather than true celestial positions because of inaccurate refraction correction.
