Which navigational error increases when an astrolabe's alidade has excessive bearing friction?

💡 Explanation

When the alidade has excessive friction, parallax error increases when aligning it because precise angle readings become difficult, leading to altitude measurement inaccuracies. Therefore incorrect navigation results, instead of time dilation drifts, declination errors, or pole inversions which relate to other astronomical phenomena or failure modes.
