Question 1439Navigation General70% to pass
You are inbound in a channel marked by a range. The range line is 040° T. You are steering 036°T. The range is in sight as shown in illustration D047NG below, and is closing. Which action should you take?
AI Explanation
The correct answer is A) Continue on course until the range is closed, then alter course to the right.
When navigating by range, you want to keep the range line centered on your bow as you approach. By continuing on your current course of 036°T, you will gradually close the range and bring it into alignment. Once the range is in line, you can then alter course to the right to 040°T to steer along the range line.
The other options are incorrect because:
B) Immediately altering course to the right would take you off the range line prematurely.
C) Continuing on 036°T until the range is in line, then altering to the left, would take you away from the intended range line.
D) Immediately altering to 040°T would be the wrong action, as you are already close to the intended range line.
