Departure is the distance along a parallel between two points. Whereas a degree of latitude is always the same distance, a degree of longitude is different in length at different latitudes. Whereas a degree of latitude is always the same distance, a degree of longitude is different in length at different latitudes.

However, my book ‘Astronomy For Astro Navigation’ describes my ‘Where To Look’ Method which is a simple ‘rule of thumb’ method of predicting which stars and planets will be visible during during civil and nautical twilight without the need to clutter the chart table with cumbersome globes, computers and large books of tables, some. What's the difference between Latitude and Longitude? The latitude specifies a location's distance north or south of the equator. The longitude specifies the location's distance east or west from an imaginary line connecting the North and South Poles, called the Prime Meridian. Latitude .

to become departure, which is expressed as a latitude unit. To find the true departure, the middle latitude has to be used, which does not lie between two latitudes. The middle latitude can be found by applying the correction to the mean latitude. This correction can be tabulated in the table reproduced in the nautical table section of this book.

In this table, as is generally the case, the index to the logarithm of every number above is omitted ; yet in the operation must be prefixed according to this remark; so the logarithm of is 2, and of is 3, and so of the rest.

I* No. Log. Log. LATITUDE AND DEPARTURE FROM PLANE COORDINATES.— The numerical values of latitude and departure of a traverse line are easily computed from the coordinates of the end stations of the line.

For traverse line AB, for example, the numerical value of latitude equals the difference between the Y coordinate of A and the Y coordinate of B, while the numerical value of departure equals the difference.

The departure of a line is its projection on the east-west meridian and is equal to the length of the line times the sine of its bearing. The latitude is the y component of the line (also known as northing), and the departure is the x component of the line (also known as easting).

The Difference of Latitude and the Departure are named, accordingly, the quadrantal course. If the course is not a whole number, repeat the procedure with the table 1° higher, then interpolate two results to find the final answers.

A meridional part for any particular latitude is the length along a meridian on a Mercator chart, measured in units of the longitude scale, between the Equator and the parallel of that particular latitude. It can be extracted from nautical tables. Difference of meridional parts is the difference between the meridional parts for any two latitudes.

Therefore, any table of azimuths (if the entering values are meridian angle, declination, and latitude) can be used for determining initial great circle course.

Tables which solve for altitude, such as Pub. can be used for determining great circle distance. The required distance is 90° - altitude.

In the tables for converting mean latitude to middle latitude, the correction for a mean latitude of 60 o and a difference of latitude of 20 o is +1 o 09’. So the middle latitude = 61 o The formula for calculating departure using the middle latitude is: Dep. = travelingartsfiesta.com cos(mid lat).

Circles parallels to the Equator are of the same latitude. Longitude: it is the West/East value of a point on Earth. Longitudes are lines going from south pole to north pole. Greenwich is on longitude 0° and any point on the line going from North pole to the South pole via Greenwich is on longitude 0°.

Nine important differences between latitude and longitude are discussed in this article. One such difference is Latitude implies the geographic coordinate which determines the distance of a point, north-south of the equator while Longitude alludes to the geographic coordinate, which identifies the distance of a point, east-west of the Prime Meridian.Traverse Tables/Adjusting Bearings and Distances In computing latitudes and departures, your arithmetical calculations can be greatly expedited by the use of a traverse table, in which latitudes and departures for any bearing and distance can be determined mostly by looking for them in the table.Sailings Plane (or Plain) Sailing.

The relationships can be laid out as two triangles. The sides of the top triangle are Distance, difference in latitude (dLat) and Departure. Departure is the longitude distance in miles. The lower triangle relates Departure to the difference in longitude (dLong.) The angle labelled mLat stands for Mean Latitude.
