History

Which navigational risk rises as chronometers experience large temperature fluctuations?

A)Increased longitudinal position error
B)Drift of celestial reference points
C)Loss of the magnetic declination
D)Unpredictable wave refraction patterns

💡 Explanation

Temperature affects a balance spring's oscillation rate through thermal expansion, causing time drift. The chronometer employs thermal compensation; however, rapid changes overwhelm this, therefore the ship accumulates longitude error faster, rather than influencing observed celestial data's inherent accuracy.
