Heading display<br />

First choose an option to explain how you wish display headings:<br />

1. If you wish that the headings are indicated by the software in geographical mode, check Geographic heading<br />

box (T is displayed against the heading field in the Cursor Data palette).<br />

2. If you wish that the headings are indicated as magnetic headings check the Magnetic heading box (Mg is<br />

displayed against the heading field in the Cursor Data palette).<br />

Note:<br />

1. True (or geographic) headings use the geographic North pole as the reference point and refer to the north<br />

maritime chart.<br />

2. Magnetic headings reference the magnetic North pole (this value is constantly moving very slowly) so you<br />

have to apply a correction factor to compensate for this offset.(see the following <strong>MaxSea</strong> World<br />

magnetic chart reference)<br />

3. Compass heading is that which is indicated on steering compass. Most GPS give the option of outputting<br />

geographic or magnetic heading.<br />
