Which consequence occurred during 18th-century celestial navigation when sextant mirror misalignment was undetected?

💡 Explanation

When sextant mirrors are misaligned, systematic errors arise because the angular measurements are consistently biased, leading to consistent discrepancies in calculated positions, especially impacting longitude determination on long voyages. Therefore, systematic longitude errors resulted, rather than random variations, dead reckoning increase, or latitude errors which would stem from other sources like weather or observational height inaccuracies.

• Which navigational error increases when using a sextant repeatedly in strong winds onboard a sailing ship?
• Which increased risk arose when Roman roads enabled rapid troop deployment?
• Which outcome resulted when ancient Andean terrace farming interrupted natural watershed flow?
• Which stability risk increases when the clay bricks of a ziggurat experience prolonged ground saturation?
• Which adaptation allowed chinampa agriculture to operate continuously in the Valley of Mexico?
• Which outcome results when early steam engine boilers experience repeated heating-cooling cycles?
