RANGES
ON RANGE LINEDESCRIPTIONA range consists of two or more fixed navigation marks situated some distance apart and at different elevations. May or may not be lighted. The shape and colours of the daymarks and the colours and characters of lights are advertised in the “list of lights”
USER’S GUIDEA range provides a leading line for navigators. When both marks are in line the observer is on the recommended track. Consult the charts for the portion of channel serviced by the range.

A minor lighted aid may display characteristics of lateral significance. Consult the “list of lights” for physical description of these aids.
MAJOR LIGHTED AIDS
Major lighted aids to navigation may display a main light, are equipped with an emergency light, and may be equipped with a fog signal or RACON.The colour and character of the light are advertised on the chart and in the publication “list of lights, buoys and fog signals”. The colour of the structure may not have lateral significance. The elevation of the light above the water level (metres (m) or feet (ft)) and nominal range (nautical miles (M)) may be indicated. Equipped with an emergency light of reduced intensity, Fl(6)15s. When the colour of the light is not specified for any marine aid to navigation light, it is white.Signal characteristics are advertised on the chart and in the “list of lights, buoys and fog signals”.A RACON (radar beacon) transmits a Morse code pulse that can be seen on a radar display distinguishing it from surrounding radar targets. Information concerning RACONS can be found in “radio aids to marine navigation”.
