What is plane 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.
What does sailing mean?
1a : the technical skill of managing a ship : navigation. b : the method of determining the course to be followed to reach a given point. 2a : the sport of handling or riding in a sailboat. b : a departure from a port.
What is short distance sailing?
Short distance sailing is a term which is applied to sailing along a rhumb-line for distances less than 600 nautical miles.
Why was the plane sailing in the end?
In the past, in order to determine distance, calculations were made based on the assumption that the earth was flat and not spherical. 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’.
What is the side of the plane sailing triangle opposite the course?
between the initial and final positions, and the departure between the initial and final positions, may be regarded as the sides of a plane right-angled triangle, the angle opposite the side representing departure being equal to the course angle.
What is the synonym of sailing?
See definition of sailing. verbtravel through water, air; glide.
What does clear sailing mean?
US. : easy progress : progress that is not blocked by anything Now that the permit has been approved, we expect to have clear sailing from here on.
Is Sailing considered a sport?
Is sailing a sport? Sailing is a sport and has been considered one for a long time. Sailing is defined as ‘the action of sailing in a boat’. Sport is defined as ‘an activity involving physical exertion and skill in which an individual or a team competes against another or others for entertainment’.
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?
Parallel sailing is the interconversion of departure and difference of longitude when a vessel is proceeding due east or due west. … It is similar to plane sailing, but uses meridional difference and difference of longitude in place of difference of latitude and departure.
What is 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 Composite great circle sailing?
A method of sailing along the shortest route possible without crossing poleward of a specified latitude. … This comprises two great circle routes, the first starting at the place of departure with its vertex on a limiting parallel of latitude.
How do you calculate great circle sailing?

|calculation for incr. latitude||formula : ( 7915,7 * log tan (45° + lat/2)) – (3437,7 * e*e * sine lat)|
|calculation for vertex latitude||formula : cos hl = cos lat a * sine oc|
What are the two categories of Mercator sailing?
In broad terms, there are two main types of sailing, namely, the Rhumb Line sailing and the Great Circle sailing.
