JP 3-50 National Search and Rescue Manual Vol I - US Navy

NOTAM for non-SAR aircraft to remain outside the area.
a. After the SMC has developed the search area, 5 miles
should be added to the outer boundaries of the coordinates
passed to the ARTCC. The SAR operations warning area will
include airspace within the expanded boundaries from the
surface normally up to 2,000 feet overland, or 6,000 feet
overwater. For international waters, the ceiling should not
exceed the base of the Oceanic Control Area (CTA) found in the
ICAO air navigation plan for that region.
b. While the SAR operations warning area is in effect,
ATC will not route IFR traffic to within 60 miles of the
boundaries laterally, or 1,000 feet above the area ceiling.
3. SAR Altitude Reservation is usually controlled airspace, and
provides for separation from ATC of controlled aircraft.
There is no assurance of separation from aircraft not under
ATC control. ATC does not issue a NOTAM for this reservation.
4. When requesting SAR airspace reservation, the SMC should
provide ATC with the following:
a. Name and organization of the person making the
request.
b. Brief incident description.
c. Estimated time of area reservation.
d. Method of contacting SMC.
e. Description of area by geographic features or
coordinates.
f. Nature of operations and altitudes for aircraft SRUs.
g. SAR aircraft staging bases, and whether non-SAR
aircraft should be asked to avoid these bases.
h. Whether aircraft carrying news media or persons on
official SAR business should operate at altitudes used by SAR
aircraft, including special instructions such as radio call
signs, frequencies of SAR aircraft, requirement to contact the
OSC, specific areas to be avoided, and direction of traffic
flow. The SMC notifies ATC when reservations are no longer
required.
D. During large-scale missions, or missions remote from adequate
communications facilities, the SMC may require an aircraft OSC to
establish a high-altitude orbit over the search area for better
communications with SRUs and shore stations. The SMC selects a position
over the search area, permitting the OSC to establish early radio
