The true course between two points is 057°. Your gyrocompass has an error of 3° east and you make an allowance of 1° leeway for a north-northwest wind. Which gyro course should be steered to make the true course good?
AI Explanation
The correct answer is A) 053°pgc.
To arrive at this answer, we need to consider the following factors:
1. The true course between the two points is 057°.
2. The gyrocompass has an error of 3° east, meaning the gyrocompass reading will be 3° higher than the true heading.
3. An allowance of 1° leeway is made for a north-northwest wind.
To determine the gyro course that should be steered to make the true course of 057° good, we need to subtract the gyrocompass error (3° east) and the leeway (1°) from the true course (057°). This results in a gyro course of 053°pgc.
The other answer choices are incorrect because they do not properly account for the gyrocompass error and the leeway adjustment.
