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.
9, 10 - Effects of crosswind and tidal current, causing the vessel's track to differ from its heading. A, B - Vessel's track. TVMDC,AW is a mnemonic for converting from true heading, to magnetic and compass headings. TVMDC is a mnemonic initialism for true heading, variation, magnetic heading, deviation, compass heading, add westerly. The most ...
W3Schools is a freemium educational website for learning coding online. [1] [2] Initially released in 1998, it derives its name from the World Wide Web but is not affiliated with the W3 Consortium. [3] [4] [unreliable source] W3Schools offers courses covering many aspects of web development. [5] W3Schools also publishes free HTML templates.
The navigator plots their 9 a.m. position, indicated by the triangle, and, using their course and speed, estimates their own position at 9:30 and 10 a.m. In navigation , dead reckoning is the process of calculating the current position of a moving object by using a previously determined position, or fix , and incorporating estimates of speed ...
Please do not use a "level one" heading (only one equals sign on each side, i.e.: =Heading=). This would cause a section heading as large as the page title at the top of the page. Heading names of sections (including subsections) should be unique on a page. Using the same heading more than once on a page causes problems:
Very short sections and subsections clutter an article with headings and inhibit the flow of the prose. Short paragraphs and single sentences generally do not warrant their own subheadings. Headings follow a six-level hierarchy, starting at 1 and ending at 6. The level of the heading is defined by the number of equals signs on each side of the ...
In nautical navigation the relative bearing of an object is the clockwise angle from the heading of the vessel to a straight line drawn from the observation station on the vessel to the object. The relative bearing is measured with a pelorus or other optical and electronic aids to navigation such as a periscope, sonar system, and radar systems ...
The first method identifies the section by using the page name and a heading (the section title as it appears in the source page). The second method allows the selection of an arbitrary "section" for transclusion, but this approach requires adding specific markup to label the desired section beforehand.
