← HistoryWhich positioning error arises when a chronometer's escapement mechanism prematurely releases in the high-latitude sailing?
A)Increased longitudinal position uncertainty✓
B)Diminished celestial observation accuracy
C)Exaggerated latitudinal coordinate deviation
D)Unpredictable drift velocity calculations
💡 Explanation
Longitudinal positioning gets unreliable during higher latitudes because the cold oil increased the balance wheel's oscillation period triggering change in timing within a chronometer; therefore, an underestimated value accumulates eastward, rather than affecting calculated relative positioning due to inaccurate measurement of angles alone.
