- Q134 - Navigation Problems: Near Coastal
176. On 23 July your 2100 ZT position is LAT 36°43.0'N, LONG 16°09.8'W, when you observed an azimuth of Polaris to determine the compass error. Polaris bears 359.0° per gyrocompass. At the time of the observation, the helmsman noted that he was heading 319.0° per gyrocompass and 331.0° per standard compass. Variation is 12.0°W. Which of the following statements is TRUE?
The gyro error is calculated as the difference between the true azimuth of Polaris and the observed gyro bearing, resulting in 1.7E. Deviation is determined by subtracting the variation from the compass error, yielding a deviation of 1.7E.
