What are navigation aids and their purposes?
A navigational aid or AtoN or navaid is any sort of marker that guides to mark safe waters and also help mariners in determining their position with respect to land or any navigational hazard or hidden danger. Traditionally aids to navigation have been physical aids such as lighthouses, buoys and beacons.
What is the difference between navigational aids and aids to navigation?
Each aid to navigation is used to provide specific information. A navigational aid (also known as aid to navigation, ATON, or navaid) is any sort of marker which aids the traveler in navigation; the term is most commonly used to refer to nautical or aviation travel.
The term “aids to navigation” includes buoys, day beacons, lights, lightships, radio beacons, fog signals, marks and other devices used to provide “street” signs on the water.

CAUTION Temporary changes or defects in aids to navigation are not indicated on this chart. See Local Notice to Mariners. During some winter months or when endan- gered by ice, certain aids to navigation are replaced by other types or removed. For details, see U.S. Coast Guard Light List.
The U.S. Aids to Navigation System is intended for use with nautical charts, which provide valuable information regarding water depths, hazards, and other features that you will not find in an atlas or road map. Buoys are placed in pairs, and you pass between them.
What is the difference between visual and auditory aids to navigation?
When the information is transmitted by light waves, the device is a visual aid to navigation; if by sound waves, an audible aid to navigation; and if by radio waves, a radio aid to navigation. Any aid to navigation using electronic equipment, whether or not radio waves are involved, may be considered an el ectronic aid to navigation.
What are the principal aids to navigation shown on MCD charts?
