← HistoryWhich navigational error increases with large sextant instrument error?
A)Increased longitudinal estimation uncertainty✓
B)Drastic deviation via course paralleling
C)Higher tidal calculation discrepancy
D)Celestial body occultation misinterpretation

Longitudinal error grows because sextant inaccuracies affect sun or star angle observations used to find Greenwich Mean Time. Therefore, GMT comparisons lead to incorrect longitude calculations, rather than course mirroring which adjusts for existing leeway.
