Course (navigation)

In navigation, an object's course is the direction over the ground along which the object is currently moving.

Course, track, route and heading

The line connecting the object's consecutive positions on the ground is referred to as the ground track. The track the object was intended to follow is called the route. For ships and aircraft, the route is represented by the great circle line that connects the previous waypoint with the next waypoint. The responsibility of a navigator is to make the track coincide as much as possible with the route. The direction of the route is called the route course. "Course" exceptionally, and arguably erroneously, may also refer to the route, such as in a course deviation indicator, in which case it no longer constitutes an angle but rather a line. The direction of the great circle line that runs from the current position to the next waypoint is called the course to steer, or the bearing to that waypoint. The tracking angle is the angle between the course to steer and the course. The heading is the direction to which the "nose" of the object is pointing, its orientation.

Fidelipac

The Fidelipac, commonly known as a "NAB cartridge" or simply "cart", is a magnetic tape sound recording format, used for radio broadcasting for playback of material over the air such as radio commercials, jingles, station identifications, and music. Fidelipac is the official name of this industry standard audio tape cartridge. It was developed in 1954 by inventor George Eash (although the invention of the Fidelipac cartridge has also been credited to Vern Nolte of the Automatic Tape Company), and commercially introduced in 1959 by Collins Radio at the 1959 NAB Convention. The cartridge was widely used at radio stations until the late 1990s, when such formats as MiniDisc and computerized broadcast automation made the Fidelipac cartridge obsolete.

History

The Fidelipac cartridge was the first audio tape cartridge available commercially, based on the endless-loop tape cartridge design developed by Bernard Cousino in 1952, while Eash shared space in Cousino's electronics shop in the early 1950s. Instead of manufacturing the Fidelipac format himself after developing it, Eash decided to license it for manufacture to Telepro Industries, in Cherry Hill, New Jersey. Telepro then manufactured and marketed the format under the Fidelipac brand name.

Crew

A crew is a body or a class of people who work at a common activity, generally in a structured or hierarchical organization. A location in which a crew works is called a crewyard or a workyard. The word has nautical resonances: the tasks involved in operating a ship, particularly a sailing ship, providing numerous specialities within a ship's crew, often organised with a chain of command. Traditional nautical usage strongly distinguishes officers from crew, though the two groups combined form the ship's company. Members of a crew are often referred to by the title Crewman.

Crew also refers to the sport of rowing, where teams row competitively in racing shells.

Crew is used colloquially to refer to a small, tight-knit group of friends or associates engaged in criminal activity. Also used in reference to the traditional "unit" of criminals under the supervision of a caporegime in the American Mafia. However, the term is not specific to (Mafia-affiliated) organized crime. Crew can also refer simply to a group of friends, unrelated to crime or violence.

Crewe (surname)

Crewe or Crew is a surname of Old Welsh origin.

Seafarer's professions and ranks

Seafarers hold a variety of professions and ranks, and each of these roles carries unique responsibilities which are integral to the successful operation of a seafaring vessel. A ship's bridge, filled with sophisticated equipment, requires skills differing from those used on the deck, which houses berthing and cargo gear, which requires skills different from those used in a ship's engine room, and so on.

The following is only a partial listing of professions and ranks. Ship operators have understandably employed a wide variety of positions, given the vast array of technologies, missions, and circumstances that ships have been subjected to over the years. Usually, seafarers work on board a ship between three and six years. Afterwards they are well prepared for working in the European maritime industry ashore. A ship's crew can generally be divided into four main categories: the deck department, the engineering department, the steward's department, and other. Generally, there are some differences between naval and civilian seafarers. One of them is that the seafarers on merchant vessels are usually not of the same nationality, so that special cross-cultural training is required, especially with regard to a lingua franca. Moreover, administrative work has increased considerably on board, partly as an effect of increased focus on safety and security. A study shows that due to this development certain skills are missing and some are desired, so that a new degree of flexibility and job sharing has arisen, as the workload of each crew member also increases.
