Quadrantal error in a gyrocompass has its GREATEST effect on which of the following?

🔍 Key Concepts

• Gyrocompass quadrantal error depends primarily on the ship’s heading, not just on latitude • Difference between cardinal headings (N, E, S, W) and intercardinal headings (NE, SE, SW, NW) • How certain compass errors are zero on some headings and maximum halfway between those headings

💭 Think About

• Ask yourself: on which headings does a quadrantal error (think: four quadrants) typically reach its maximum value? • Consider whether this type of error is usually largest on pure north/south headings, pure east/west headings, or midway between those directions. • Think about whether the word ‘quadrantal’ is referring more to changes in heading or changes in latitude.

✅ Before You Answer

• Identify which choices refer to heading and which refer to geographic location (latitude). • Recall that some compass errors are zero on cardinal headings and largest between them—decide if quadrantal error is one of these. • Before choosing, be sure you can explain to yourself: “Why would this error be largest on that particular type of heading?” rather than just memorizing a phrase.
