The true course between two points is 194°. Your gyrocompass has an error of 2°W and you make an allowance of 1° leeway for a southwest wind. What gyro course should you steer to make the true course good?
AI Explanation
The correct answer is A) 197°pgc.
To arrive at this answer, we need to consider the following factors:
- The true course between the two points is 194°.
- The gyrocompass has an error of 2°W, meaning the gyro reading is 2° less than the true course.
- There is an allowance of 1° leeway for a southwest wind.
To make the true course of 194° good, we need to adjust the gyro course to account for the gyro error and the leeway. The gyro course should be 197°, which is the true course (194°) plus the gyro error (2°W) and the leeway (1°).
The other options are incorrect because they do not properly account for the gyro error and leeway. For example, option B (199°pgc) does not consider the leeway, while option C (195°pgc) and option D (193°pgc) do not correctly factor in the gyro error.
