You desire to make good a true course of 129°. The variation is 7°E, magnetic compass deviation is 4°E, and gyrocompass error is 2°W. An easterly wind produces a 4° leeway. What is the course to steer per standard magnetic compass to make the true course good?

A 126°psc

B 116°psc

C 122°psc

D 114°psc

AI Explanation

The correct answer is D) 114°psc. To arrive at this answer, we need to apply the following formula: True Course = Compass Course + Variation + Deviation + Leeway Given information: - True Course = 129° - Variation = 7°E - Magnetic Compass Deviation = 4°E - Gyrocompass Error = 2°W - Leeway = 4°E Applying the formula: Compass Course = True Course - Variation - Deviation - Leeway Compass Course = 129° - 7°E - 4°E - 4°E Compass Course = 114°psc The other options are incorrect because they do not correctly apply the formula to arrive at the Compass Course that will make the True Course of 129° good.
