Question 276Navigation General

The correct answer is D) All of the above. In the U.S. Aids to Navigation System, lateral aids as seen entering from seaward will display lights with the characteristics of occulting, flashing, or quick flashing. These different light characteristics help mariners identify the type and purpose of the aid to navigation. Occulting lights have a regular pattern of light and eclipse (dark) periods, flashing lights have a distinct pattern of light and dark periods, and quick flashing lights have a rapid sequence of light flashes. All of these light characteristics are used to mark lateral aids when viewed from the seaward side.
