Detailed answer to the quiz question
A beacon is a permanently installed light signal that plays an important role in the navigation of ships and airplanes. These signals are used for orientation in poor visibility conditions such as fog, rain or darkness.
Beacons use powerful light sources that flash at regular intervals or remain lit continuously. The characteristic flashing sequence (identification) of each beacon is unique and enables navigators to distinguish the individual beacons and determine their exact position.
Despite modern navigation systems such as GPS, beacons remain an indispensable safety instrument in shipping and aviation. They provide additional protection and are particularly useful in situations where electronic systems fail or are disrupted.
Beacons therefore make a decisive contribution to safety at sea and in the air by providing clear landmarks and warning of potential dangers.
