← HistoryWhich navigational error increased when 18th-century chronometer spring accuracy fell below thermal compensation thresholds?
A)Longitudinal position estimate drift widening✓
B)Latitudinal position calculation destabilization
C)Celestial altitude measurement scaling fall
D)Magnetic declination correction data skewing
💡 Explanation
Incorrect thermal Compensation affects isochronism – timekeeping precision–which is linked directly astronomical observations which enabled longitude calculations. Therefore, a chronometer is limited to accurately determine longitude, rather than issues with declination, latitude, or altitude.
