EXERCISE – 6

1. On 29^th Nov 1992, AM at ship in DR 26⁰ 27’N 130⁰ 27’W, the azimuth of the Sun was 130⁰(C) when chron showed 05h 49m 20s. If chron error was 01m 31s fast and variation was 3⁰E, find the deviation for the ship’s head.

Solution-

2. On 22^nd Sept 1992, PM at ship in DR 18⁰ 20’N 85⁰ 40’E, the azimuth of the Sun was 265⁰(C) when chron showed 10h 03m 20s. If chron error was 06m 18s slow and variation was 2⁰E, calculate the deviation of the compass.

Solution-

3. On Jan 19^th 1992, in DR 40⁰ 16’S 175⁰ 31’E, the azimuth of the Sun was 267⁰(C) at 1618 ship’s time. If the ship’s time difference was 11h 30m from GMT and variation was 2.3⁰E, find the deviation for the ship’s head.

Solution-

4. On 30^th April 1992, in DR 00⁰0’ 60⁰ 12’W, the Sun bore 080⁰(C) when chron showed 10h 57m 43s. If chron error was 03m 09s slow and variation was 1⁰W, find the deviation of the compass.

Solution-

5. On 31^st Aug 1992, in DR 10⁰ 11’S 000⁰ 00’, the azimuth of the Sun was 282⁰(C) when chron showed 05h 10m 25s. If chron error was 00m 05s fast and variation was 30E, find the deviation for the ship’s head.
