← HistoryWhich consequence occurs when a sextant's mirrors become misaligned during celestial fix calculation?
A)Cumulative refraction measurement error
B)Parallax distortion field compensation
C)Observed altitude value inaccurate✓
D)Chronometer synchronization drift rate
💡 Explanation
An inaccurate observed altitude results because the mechanism of angular measurement is compromised; misalignment induces incorrect angle reading, therefore observation error occurs rather than issues involving refraction, parallax, or timekeeping affecting navigation accuracy.
