← HistoryWhich risk increased at sea when a ship's chronometer malfunctioned from physical shock?
A)Increased error in longitude calculation✓
B)Increased need estimating ship speed
C)Increased use of celestial averaging
D)Increased susceptibility dead reckoning errors
💡 Explanation
Erroneous time impacts celestial navigation because longitude calculation relies on accurate time; a ship's chronometer enabled mariners to measure longitude based on the time difference. Therefore, positional uncertainty grew, rather than reliance on ship speed or dead reckoning alone.
