← HistoryWhich navigational error increases when a user neglects index error correction while using a sextant at sea?
A)Increased latitude calculation error✓
B)Increased longitude calculation error
C)Consistent bearing calculation offsets
D)Underestimated ship speed calculation
💡 Explanation
When index error is neglected, systematic angular mismeasurements during celestial body sightings occurs because the sextant's mirrors aren't perfectly aligned, creating constant altitude errors directly affecting latitude calculations. Therefore, latitude error increases, rather than longitude (dependent on time), bearing (dependent on compass/direction), or speed (dependent on log),
