- Q134 - Navigation Problems: Near Coastal
200. On 3 October your 0330 zone time (ZD + 5) DR position is LAT 47°41'N, LONG 86°49'W. At that time, you observe Polaris bearing 357.5°pgc. The chronometer time of the observation is 08h 32m 04s, and the chronometer is 0m 27s slow. The variation is 5.5°W. What is the gyro error?
The gyro error is 2.0E, calculated by subtracting the observed gyro bearing from the true azimuth of Polaris obtained from the Nautical Almanac and Polaris tables (359.5 — 357.5 = 2.0).
