What is plain sailing?

What is plain sailing in navigation?

Plane sailing (also, colloquially and historically, spelled plain sailing) is an approximate method of navigation over small ranges of latitude and longitude. With the course and distance known, the difference in latitude ΔφAB between A and B can be found, as well as the departure, the distance made good east or west.

How do you use plain sailing?

If you say that a task was not all plain sailing, you mean that it was not very easy. Pregnancy wasn’t all plain sailing and once again there were problems. We know it won’t be plain sailing because there are no easy games at this level.

What are the limitations of plane sailing?

Plane sailing is not intended for distances of more than a few hundred miles. Since the track is cutting all meridians at the same angle, Plane Sailing is also one of the methods of Rhumb Line Sailing.

What is departure plane sailing?

These relationships are now known as the plane sailing formulae, namely: departure = distance x sine course d. lat. =distance xcosine course. Now it is a common belief amongst navigators that this artifice represents a. triangle on the Earth’s surface.

What are meridional parts?

Definition of meridional part

: the linear length of one minute of longitude on a Mercator chart.

What is smooth sailing?

Definition of smooth sailing

: easy progress without impediment or difficulty After the mix-up was rectified, it was smooth sailing again.—

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.

What is parallel sailing?

Definition of 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.

What is the difference between plane sailing and Mercator sailing?

* It is similar to plane sailing except that plane sailing is used for small distance. * In mercator sailing the d’lat is expressed in longitudinal units, which is the difference of meridianal parts. * In plane sailing the d’long is expressed in latitude units or Nautical miles.

What is the rhumb line in sailing?

In navigation, a rhumb line, rhumb (/rʌm/), or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true north.

What is Traverse sailing?

Definition of traverse sailing

: plane sailing in which a ship follows two or more courses in succession with the difference in latitude and departure being added algebraically to find a single resultant course and distance.

What is Meridian sailing?

Definition of meridian sailing

: sailing north or south —opposed to parallel sailing.

What is composite sailing?

Definition of composite sailing

: a combination of great circle and parallel sailing in navigation.
