The true course between two points is 078°. Your gyrocompass has an error of 2°E. You make an allowance of 3° leeway for a north wind. What gyro course should be steered to make the true course good?
AI Explanation
The correct answer is D) 073°pgc.
To arrive at this answer, we need to consider the following:
1. The true course between the two points is 078°.
2. The gyrocompass has an error of 2°E, meaning the gyro reading is 2° higher than the true heading.
3. There is an allowance of 3° leeway for a north wind.
To make the true course of 078° good, we need to subtract the gyrocompass error (2°E) and the leeway (3°) from the true course. This results in a gyro course of 073°pgc.
The other options are incorrect because they do not properly account for the gyrocompass error and leeway.
