: 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.
The most common navigation methods are satnav, dead reckoning, and radar navigation.
- Dead reckoning.
- Pilotage.
- Celestial navigation.
- Inertial navigation.
- Radio navigation.
- Radar navigation.

Definition of plane sailing
1 : the navigation or conducting of a ship by neglecting the earth’s curvature and considering the earth or a part of it as a plane.
What is the traverse table?
Definition of traverse table. 1 : a navigation or surveying table giving the difference of latitude and departure corresponding to any given course and distance and containing the lengths of the two sides of a right-angled triangle usually for every degree of angle and for all lengths of the hypotenuse from 1 to 100.
What is the purpose of sailing calculation?
To calculate the longitude, the spherical sailings are necessary. The Plane Sailing method is used to find the approximated course and distance between two positions that are on different latitudes.
Which sailing is more accurate?
Charts used on board ships generally are Mercator charts. On these charts bearings, courses and distances can be directly read off or plotted on the charts. For calculating course and distance between two given points on surface of the earth, the Mercator sailing formula is more accurate than plane sailing formula.
Three main types of navigation are celestial, GPS, and map and compass. In order to better understand why we teach map and compass at High Trails, it is helpful to learn the basics of all three techniques.
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 parallel sailing is important?
By parallel sailing we mean travelling along a parallel of latitude from one place to another. … The distance decreases as the latitude increases. Because of this, the distance along a chosen latitude is referred to as “Departure” and it is expressed in nautical miles.
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 mid latitude sailing?
[′mid·əl ¦lad·ə‚tüd ‚sāl·iŋ] (navigation) A method of converting departure into difference of longitude, or vice versa, when the true course is not 090° or 270° by assuming that such a course is steered at the middle latitude.
Why it is called Plane sailing?
To make calculations simple, sailors assumed that the ship was sailing on a flat or a ‘plane surface’. The original expression was, in fact, ‘plane sailing’. Since spelling had not been standardised, the two words ‘plain’ and ‘plane’ were used interchangeably.
How is plane sailing calculated?
When a ship sails along any rhumb line except a meridian or parallel of latitude, the distance sailed, the d. … These relationships are now known as the plane sailing formulae, namely: departure = distance x sine course d. lat. =distance xcosine course.
