Question 96Navigation General

The correct answer is A) Gray lines on the uppermost inset chart. The annual rate of change for magnetic variation is typically shown on pilot charts through gray lines on an inset chart in the upper portion of the chart. These gray lines indicate the annual change in magnetic variation, allowing mariners to adjust their compass readings accordingly. The other options are incorrect: B) Annual rate of change is not shown, C) Red lines on the main body of the chart are used to depict lines of equal magnetic variation, not the annual rate of change, and D) the annual rate of change is not shown in parentheses on the lines of equal magnetic variation.
