Which consequence resulted from inconsistent plate alignment in early astrolabes used for navigation?

💡 Explanation

When plates are misaligned, parallax error occurs because the user observes celestial objects through different angles relative to true coordinates, leading to a gradual accumulation of positioning inaccuracies on each sighting. Therefore cumulative error results, rather than structural issues, manufacturing problems, or magnetic interference which depend on material properties and external fields.
