← HistoryWhich limiting factor reduces accuracy when using sextants from small craft?
A)Atmospheric refraction variability increases
B)Parallax error becomes significant✓
C)Instrument weight becomes restrictive
D)Temporal synchronization becomes problematic
💡 Explanation
Parallax error increases because the observer's eye has a larger relative displacement from the theoretical observation plane, therefore, small craft introduce greater angle estimation offset impacting the reading, rather than stable fixed platform measurements.
