CHAPTER II DETERMINATION OF THE "D. R." ALTITUDE AND AZIMUTH The "D. R." altitude, or the altitude of the sun as it would be seen from the place in which the traveller supposes himself to be, can be found by mathematical calculation only. This calculation involves the solution of a spherical triangle, and this can be effected only by the formulas of trigonometry. By the aid of special tables, or mechanical devices, however, these calculations may be put into such simple form that the practical navigator need have no knowledge of trigonometry and can solve the problem with a few simple additions. The navigator begins with his "D. R." position, that is, with the latitude and the longitude of the place in which he believes himself to be, together with the chronometer time at which he made an observation of the sun. The chronometer time is first corrected for "chronometer error," and then to this result is applied the "equation of time," as taken from the "Nautical Almanac," and thus is found the Greenwich Apparent time at which the observation was made. From this subtract the longitude of the place, if west (expressed in hours); add, if east; and the result is the Local Apparent time, or ship's time. This measures the angular distance of the sun east or west of the meridian, which angular distance is known as the Hour Angle. On ordinaryclocks or chronometers, however, the noon hour is denoted by twelve (XII), so that an apparent time of eleven (XI) hours means that it will require one hour for the sun to reach the meridian. Hence, in the morning the hour angle is found by subtracting the apparent, or ship's time, from twelve (12) hours, but in the afternoon the apparent time and the hour angle are identically the same. The hour angle, thus...
