← HistoryWhich consequence results when index error affects a sextant during a voyage?
A)Consistent angular measurement errors occur✓
B)Chronometer accuracy slowly degrades over time
C)Star identification ambiguities gradually grow
D)Ship's hull plating rapidly corrodes
💡 Explanation
Consistent angular measurement errors inevitably occur because index error introduces a systematic offset into all sextant readings, violating the Angle of Incidence theory; therefore celestial altitude differences remains skewed systematically rather than randomly.
