Aids to Navigation are tools and devices that help guide mariners and pilots safely through waterways and airspace. These aids include lighthouses, buoys, beacons, and navigational charts, which provide essential information about hazards, routes, and positions. They are crucial for ensuring safe travel on water and in the air. These aids are maintained by various organizations, such as the U.S. Coast Guard and international maritime authorities. They use standardized symbols and signals to communicate important information to navigators. Proper use of these aids helps prevent accidents and ensures efficient transportation across oceans and skies.
