8 - Magnetic heading, the compass heading corrected for magnetic deviation but not magnetic variation; thus, the heading reliative to magnetic north. 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 ...
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.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.
7 - Compass heading or compass course, before correction for magnetic deviation or magnetic variation. 8 - Magnetic heading, the compass heading corrected for magnetic deviation but not magnetic variation; thus, the heading reliative to magnetic north. 9, 10 - Effects of crosswind and tidal current, causing the vessel's track to differ from its ...
A radio magnetic indicator (RMI) is an alternate ADF display providing more information than a standard ADF. While the ADF shows relative angle of the transmitter with respect to the aircraft, an RMI display incorporates a compass card, actuated by the aircraft's compass system, and permits the operator to read the magnetic bearing to or from ...
The template should automatically detect the correct title of the outline article, as long as it has been named in one of the more common patterns for such articles (check the link to be sure it worked). If the template doesn't detect the correct name automatically, then add it in manually like this: {{For outline|Title of outline article}}

An outline, also called a hierarchical outline, is a list arranged to show hierarchical relationships and is a type of tree structure. An outline is used [1] to present the main points (in sentences) or topics of a given subject. Each item in an outline may be divided into additional sub-items.
The principal lines are oriented to the magnetic north pole. [12] Thus the grid lines varied slightly for charts produced in different eras, due to the natural changes of the Earth's magnetic declination. [12] These lines are similar to the compass rose displayed on later maps and charts. "All portolan charts have wind roses, though not ...
