Warning Areas extend outward from which geographical feature?

Warning areas extend outward from the US coast. These areas are designated in the airspace to warn pilots about potential hazards or activities that may pose risks, such as military operations or testing exercises often associated with coastal regions. The designation of warning areas is essential for ensuring pilot awareness and safety when flying in or near those zones.

In the context of aviation, these areas provide a crucial service by indicating where there may be increased risks due to activities such as live-fire exercises or other operations that could affect aviation safety. This is particularly relevant over coastal waters where such activities may occur, thus justifying the extension of warning areas from the US coast outward into the surrounding airspace.
