← HistoryWhich consequence occurs when a navigator misaligns a sextant's mirrors?
A)Horizon error introduces angular offset✓
B)Index error negates celestial reading
C)Parallax errors increase proportionally
D)Limb darkening reduces observation resolution
💡 Explanation
Horizon error arises because sextant side mirrors not reflecting horizon accurately. The tilting causes incorrect altitude measurements, therefore altering the perceived position, rather than parallax or celestial resolution. The mechanism dominating misalignment is horizon error.
