Question 65Navigation General

70% to pass

If the gyrocompass error is east, what describes the error and the correction to be made to gyrocompass headings to obtain true headings?

A The readings are too low and the amount of the error must be subtracted from the compass to obtain true
B The readings are too high (large numerically) and the amount of the error must be added to the compass to obtain true
C The readings are too low (small numerically) and the amount of the error must be added to the compass to obtain true
D The readings are too high and the amount of the error must be subtracted from the compass to obtain true
AI Explanation

The correct answer is C) The readings are too low (small numerically) and the amount of the error must be added to the compass to obtain true. When the gyrocompass error is east, it means the gyrocompass reading is lower than the true heading. To obtain the true heading, you need to add the amount of the east error to the gyrocompass reading. This is because the gyrocompass is reading too low, and adding the error will bring the reading up to the true heading. The other options are incorrect because they do not properly describe the relationship between the gyrocompass error and the correction needed to obtain the true heading when the error is east.
