You desire to make good a true course of 329°. The variation is 13° W, magnetic compass deviation is 4°E, and gyrocompass error is 2°W. A southerly wind produces a 1° leeway. What is the course to steer per standard magnetic compass to make the true course good?
AI Explanation
The correct answer is C) 337°psc.
To calculate the course to steer per the standard magnetic compass, we need to apply the following corrections to the desired true course of 329°:
- Variation of 13°W (add to true course)
- Magnetic compass deviation of 4°E (subtract from true course)
- Gyrocompass error of 2°W (add to true course)
- Leeway of 1°S (add to true course)
Applying these corrections, the course to steer is:
329° + 13° - 4° + 2° + 1° = 337°psc
The other options are incorrect because they do not properly account for all the necessary corrections to arrive at the correct course to steer.
