Question 173Navigation General

The correct answer is C) Off-air times of radio beacons when scheduled for routine maintenance. A NAVAREA warning is a navigational warning issued by the National Geospatial-Intelligence Agency (NGA) to alert mariners of potential hazards or changes to navigation in a specific area of the world's oceans. These warnings typically include information about things like malfunctioning navigation aids, drifting objects, or other temporary obstructions or dangers. Off-air times of radio beacons during routine maintenance would be the type of information that would be disseminated through a NAVAREA warning. The other options are incorrect because they do not represent the type of information typically included in a NAVAREA warning. Military exercises, drifting buoys, and the extinguishment of a light within a bay would not necessarily require a worldwide navigational warning.
