Which error increased in 18th-century celestial navigation when inaccurate chronometers overestimated eastbound travel time during ocean voyages?

💡 Explanation

When an inaccurate chronometer overestimates eastbound travel time, longitude miscalculation occurs because this leads to a perceived later local time compared to the actual Greenwich Mean Time, shifting the calculated position eastward. Therefore an eastward positional displacement results, rather than altitude, declination, or latitude errors which depend on sextant measurements and observation time of celestial bodies.
