What is a rhumb line used for?

What is a rhumb line used for?

A Rhumb Line (also known as a loxodrome) is a line on the earth’s surface that crosses all meridians at the same angle. It is used as the standard method of plotting a ship’s course on a chart.

What is the meaning of rhumb?

Definitions of rhumb. a line on a sphere that cuts all meridians at the same angle; the path taken by a ship or plane that maintains a constant compass direction. synonyms: loxodrome, rhumb line.

What is the characteristic of a rhumb line?

rhumb line. [geodesy] A complex curve on the earth’s surface that crosses every meridian at the same oblique angle. A rhumb line path follows a single compass bearing; it is a straight line on a Mercator projection, or a logarithmic spiral on a polar projection.

What is rhumb line in aviation?

a curve on the surface of a sphere that cuts all meridians at the same angle. It is the path taken by a vessel or aircraft that maintains a constant compass direction. Also called loxodrome, rhumb.

Is equator a rhumb line?

All parallels, including the equator, are rhumb lines, since they cross all meridians at 90°. Additionally, all meridians are rhumb lines, in addition to being great circles.

What is Mercator sailing?

Mercator Sailing is another method of Rhumb Line Sailing. It is used to find the course and distance between two positions that are in different latitudes from the large D. Lat. and distance. It is similar to plane sailing, except that plane sailing is used for small distances.

Why is it called a rhumb line?

A rhumb line appears as a straight line on a Mercator projection map. The name is derived from Old French or Spanish respectively: “rumb” or “rumbo”, a line on the chart which intersects all meridians at the same angle. On a plane surface this would be the shortest distance between two points.

Is a parallel a rhumb line?

All parallels, including the equator, are rhumb lines, since they cross all meridians at 90°.

What is the difference between a great circle and a rhumb line?

A rhumb line can be contrasted with a great circle, which is the path of shortest distance between two points on the surface of a sphere. In other words, a great circle is locally “straight” with zero geodesic curvature, whereas a rhumb line has non-zero geodesic curvature.

Is rhumb line a great circle?

A rhumb line can be contrasted with a great circle, which is the path of shortest distance between two points on the surface of a sphere. On a north–south passage the rhumb line course coincides with a great circle, as it does on an east–west passage along the equator.

What is parallel sailing?

: spherical sailing in which the course is along a parallel and departure is the product of cosine latitude times the difference of longitude —opposed to meridian sailing.

Is Equator a rhumb line?
