The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed. [1] [2] [3] [page needed] The path that a vessel follows is called a track or, in the case of aircraft, ground track (also known as course made good or course over the ground). [1] The intended track is a route.
Parallel indexing is a technique defined by William Burger in the 1957 book The Radar Observer's Handbook. [35] This technique involves creating a line on the screen that is parallel to the ship's course, but offset to the left or right by some distance. [35] This parallel line allows the navigator to maintain a given distance away from hazards ...
Navigation and location of the ship by means of the analysis of the data provided by accelerometers and/or gyroscopes located on board, which integrate the accelerations experienced in complex electronic systems, that converted into velocities (in the 3 possible axes of displacement) and according to the observed courses, make it possible to ...
To change the course of a ship by tacking. "Ready about" is the order to prepare for tacking. [8] above board On or above the deck; in plain view; not hiding anything. Pirates would often hide their crews below decks, thereby creating the false impression that an encounter with another ship was a casual matter of chance rather than a planned ...
Orthodromic course drawn on the Earth globe. Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle.
It acted as both a cargo ship, carrying close to 10 million pounds of tea between 1870 and 1877, and a training ship, and was known as one of the fastest ships of its time.
Ship stability – Ship response to disturbance from an upright condition; Ship motion test – Scale model a hydrodynamic test to predict full size behaviour; Six degrees of freedom – Types of movement possible for a rigid body in three-dimensional space; Flight dynamics – Study of the performance, stability, and control of flying vehicles
Map of the world produced in 1689 by Gerard van Schagen.. The history of navigation, or the history of seafaring, is the art of directing vessels upon the open sea through the establishment of its position and course by means of traditional practice, geometry, astronomy, or special instruments.
