On 28 November your vessel's 0712 zone time DR position is LAT 26°54'S, LONG 45°18'W, when you take an azimuth of the Sun. Determine the gyro error using the azimuth information. Chronometer time: 10h 09m 18s Chronometer error: slow 02m 54s Gyro bearing: 102°

Correct Answer: Option B — 0.6°W

Calculate the Sun's true azimuth using the LHA and declination from the Nautical Almanac. Compare the true azimuth to the gyro bearing of 102°. The difference between the true azimuth and the gyro bearing provides the gyro error, which calculates to 0.6°W.
