What is a NAVAID?

NAVAIDs are navigational aids that help you determine your position by providing bearing or range to a known point. With a bearing to the aid, you plot a line of position; with a range, you plot a circle of possible positions. Intersecting two such lines (or a line and a circle from two different aids) fixes the vessel’s position. Examples include lighthouses, buoys, radio beacons, and GPS. The other choices describe instruments that measure speed, depth, or weather data, which are not NAVAIDs.
