Which error increases when using a sextant without correcting for index error?

💡 Explanation

When a sextant's mirrors aren't perfectly aligned, index error exists because angles are consistently misread, leading to inaccuracies. This impacts longitude calculations during celestial navigation. Therefore longitude error increases, rather than landmark altitude, speeds, or sundial time, which use separate measurement techniques.
