Question 44Navigation Problems
70% to passThe 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?
A
079°pgc
B
075°pgc
C
077°pgc
D
073°pgc
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.
