- Q126 - Navigation Problems: Near Coastal
191. On 30 July, your 0200 zone time (ZD +4) DR position is LAT 43°48'N, LONG 78°00 W. At that time, you observe Polaris bearing 008.7°psc. The chronometer time of the observation is 05h 58m 07s, and the chronometer is 0m 23s slow. The variation is 10.5°W. What is the deviation of the magnetic compass?
The true azimuth of Polaris is determined from the Nautical Almanac, then compared to the observed compass bearing, accounting for variation, to calculate a compass deviation of 3.0E.
