14 CFR Section 91.119, Minimum Safe Altitudes: General.
7-5-5. LOCAL OPERATIONS
a. Authorize local SVFR operations for a specified
period (series of landings and takeoffs, etc.) upon
request if the aircraft can be recalled when traffic or
weather conditions require. Where warranted, LOAs
may be consummated.
PHRASEOLOGYLOCAL
SPECIAL V-F-R OPERATIONS IN THE
IMMEDIATE VICINITY OF (name) AIRPORT ARE
AUTHORIZED UNTIL (time). MAINTAIN SPECIAL
V-F-R CONDITIONS.
REFERENCEFAAO
JO 7210.3, Para 4-3-2, Appropriate Subjects.
b. Control facilities may also authorize an FSS to
transmit SVFR clearances so that only one aircraft at
a time operates in the Class B, Class C, Class D, or
Class E surface areas unless pilots agree that they
will maintain visual separation with other aircraft
operating in the Class B, Class C, Class D, or ClassE
surface areas. Such authorization concerning visual
separation by pilots shall be contained in a LOA
between the control facility and the FSS.

7-5-6. CLIMB TO VFR
Authorize an aircraft to climb to VFR upon request if
the only weather limitation is restricted visibility.
PHRASEOLOGYCLIMB
TO V-F-R WITHIN (name) SURFACE
AREA/WITHIN (a specified distance) MILES FROM
(airport name) AIRPORT, MAINTAIN SPECIAL V-F-R
CONDITIONS UNTIL REACHING V-F-R.

7-5-7. GROUND VISIBILITY BELOW ONE
MILE
14 CFR Part 91 does not prohibit helicopter SVFR
flight when the visibility is less than 1 mile. Treat
requests for SVFR fixed wing operations as follows
when the ground visibility is officially reported at an
airport as less than 1 mile:
a. Inform departing aircraft that ground visibility
is less than 1 mile and that a clearance cannot be
issued.
b. Inform arriving aircraft, operating outside of a
Class B, Class C, Class D, or Class E surface area, that
ground visibility is less than 1 mile and that, unless an
emergency exists, a clearance cannot be issued.
c. Inform arriving aircraft, operating VFR/SVFR
within a Class B, Class C, Class D, or Class E surface
area, that ground visibility is less than 1 mile and
request the pilot to advise intentions.
PHRASEOLOGY-
(Name of airport) VISIBILITY LESS THAN ONE MILE.
ADVISE INTENTIONS.
NOTEClear
an aircraft to land at an airport with an operating
control tower, traffic permitting, if the pilot reports the
airport in sight. The pilot is responsible to continue to the
airport or exit the surface area. 14 CFR Section 91.157
prohibits VFR aircraft (other than helicopters) from
landing at any airport within a surface area when ground
visibility is less than 1 mile. A pilot could inadvertently
encounter conditions that are below SVFR minimums after
entering a surface area due to rapidly changing weather.
The pilot is best suited to determine the action to be taken
since pilots operating under SVFR between sunrise and
sunset are not required to be instrument rated, and the
possibility exists that flight visibility may not be the same
as ground visibility. 14 CFR Section 91.3 authorizes a pilot
encountering an inflight emergency requiring immediate
action to deviate from any rule of 14CFR Part 91 to the
extent required to meet that emergency. Flight into adverse
weather conditions may require the pilot to execute the
emergency authority granted in 14 CFR Section 91.3 and
continue inbound to land.
d. Authorize scheduled air carrier aircraft in the
U.S. to conduct operations if ground visibility is not
less than 1/2 statute mile.
NOTE-
14 CFR Part 121 permits landing or takeoff by domestic
scheduled air carriers where a local surface restriction to
visibility is not less than 1/2 statute mile, provided all turns
after takeoff or before landing and all flights beyond
1statute mile from the airport boundary can be
accomplished above or outside the area so restricted. The
pilot is solely responsible for determining if the nature of
the visibility restriction will permit compliance with the
provisions of 14 CFR Part 121.
e. Clear an aircraft to fly through the Class B,
Class C, Class D, or Class E surface area if the
aircraft reports flight visibility is at least 1 statute
mile.
