Definition
A coordinated service that uses available personnel and aircraft to locate and assist persons or aircraft in distress. In the United States, SAR is provided by the U.S. Coast Guard over maritime regions and by the U.S. Air Force over the inland region, working with state, local, and volunteer resources such as the Civil Air Patrol.
Plain English
If an aircraft goes missing or a pilot is in trouble, SAR is the system that organizes the search and sends help. It pulls together military, government, and volunteer resources to find people and get them to safety.
Context Anchor
You may see SAR mentioned in reports of overdue aircraft, emergency communications, flight plan follow-up, or discussions of distress signals.
Why Pilots Care
Pilots understand that filing a flight plan or activating an emergency beacon can trigger SAR services if they do not arrive or report as expected.
Intuition Check
SAR is not only crash recovery. It can also mean looking for an overdue aircraft or helping someone who is still alive and needs assistance.
Example Sentence 1
Because the pilot had filed a VFR flight plan and failed to close it on arrival, SAR was alerted within an hour of the expected landing time.
Example Sentence 2
After losing radio contact, air traffic control began SAR operations to locate the missing aircraft.
