Definition
A branch of the United States armed forces operating under the Department of Homeland Security in peacetime and the Department of the Navy in wartime, responsible for maritime safety, security, search and rescue, law enforcement at sea, and the operation of aids to navigation. In aviation contexts, the Coast Guard operates fixed-wing aircraft and helicopters used primarily for search and rescue, maritime patrol, and medical evacuation over coastal and offshore waters.
Plain English
A U.S. military service that protects the country's coasts and waterways. It runs rescue aircraft and helicopters that pilots may hear about or work with during search and rescue operations, especially over water.
Context Anchor
Seen in FAA guidance when outside agencies are listed as possible sources of information or assistance, especially for flights near coastal or overwater areas.
Why Pilots Care
Overwater flights may require coordination with the U.S. Coast Guard for emergency response, flight following, or post-incident support.
Intuition Check
Do not think of the U.S. Coast Guard as only a boat service. It also operates aircraft and can be part of aviation-related rescue and information support near water.
Example Sentence 1

Example Sentence 2
