← HistoryWhich consequence results when an 18th-century navigator neglects calibrating their marine chronometer to account for the Equation of Time?
A)Inaccurate longitude calculation occurs✓
B)Significant variation due to magnetic deviation
C)Unreliable sextant altitude measurement
D)Capsize vulnerability under sail increases
💡 Explanation
Inaccurate longitude calculation results from neglecting the Equation of Time because of discrepancies between mean solar time and apparent solar time; therefore, the calculated position drifts over days at sea, rather than affecting magnetic deviation measurements or sextant readings alone.
