- Q134 - Navigation Problems: Near Coastal
93. On 10 February in DR position LAT 25°32.0'N, LONG 135°15.0'E, you observe an amplitude of the Sun. The Sun's center is on the celestial horizon and bears 109°psc. The chronometer reads 09h 43m 25s and is 03m 20s fast. Variation in the area is 4.5°W. What is the deviation of the standard magnetic compass?
The correct deviation is 1.6E. The true bearing was calculated as 106.1T using the latitude and declination, and comparing this to the observed compass bearing of 109psc, along with the variation of 4.5W, yields a deviation of 1.6E.
