← HistoryWhich navigation error arises when horizon visibility changes drastically, hindering precise sextant measurements?
A)Index error amplification
B)Refraction angle miscalculation
C)Parallax-induced azimuth deviation
D)Dip of the horizon variation✓
💡 Explanation
Varying visibility alters the observed dip of the horizon, impacting the sextant's angle reading because this dip represents the angle between the visible and true horizontal. Therefore, imprecise navigational positioning arises, rather than simple instrument errors or parallax effects.
