Which risk increases when a large astrolabe's alidade sighting vane becomes warped?

💡 Explanation

Warped alidades causes increased observer parallax because angular measurements are skewed therefore precise angular readings cannot be observed, rather than maintaining accuracy as warping introduces systematic errors.

• Which consequence resulted when historical rope bridges experienced dynamic load increases?
• Within Byzantine naval sieges, which risk increased when Greek fire projectors became inoperable?
• Which outcome results when spherical aberration remained uncorrected in early Islamic telescope lenses?
• During siege warfare in ancient Greece, which consequence resulted when defenders repeatedly poured water onto wooden siege towers?
• Which risk increased for early cast-iron bridge designs?
• Which consequence arises from index error in a navigational sextant?
