Section 6. Special VFR Operations

1. AUTHORIZATION

1. SVFR operations in weather conditions less than VFR minima are authorized:

1. For helicopters and fixed‐wing aircraft at any location not prohibited by 14 CFR 91, Appendix D, Section 3, or when an exception to 14 CFR 91, Appendix D, Section 3, has been granted and an associated letter of agreement established.

1. Only within surface areas.
2. Only when requested by the pilot.

1. When the primary airport is reporting VFR, SVFR operations may be authorized for aircraft transiting surface areas when the pilot advises the inability to maintain VFR.
2. Control facilities must always retain SVFR operations authority when IFR operations are being conducted in surface areas.

1. REQUESTS FOR SPECIAL VFR CLEARANCE

1. Transmit SVFR clearances only for operations within surface areas on the basis of weather conditions. If weather conditions are not reported, transmit an SVFR clearance whenever a pilot advises unable to maintain VFR and requests an SVFR clearance, provided the pilot reports having at least 1‐mile flight visibility.

1. Transmit clearance for local SVFR operations for a specified period (series of takeoffs and landings, etc.) upon request if the aircraft can be recalled when traffic or weather conditions require. Letters of agreement may be established.

1. If an aircraft operating under VFR attempts to enter, depart, or operate within surface areas contrary to the provisions of 14 CFR 91.155 (basic VFR weather minimums), ensure the pilot is aware of the current weather conditions. Provide the following information:

1. At airports with commissioned automated weather with continuous automated voice capability, instruct the pilot to monitor the automated broadcast and advise intentions.

1. At airports without a commissioned automated weather, or, if the pilot is unable to receive the automated weather broadcast, issue the most current weather report available. Advise the pilot that the weather is below VFR minima, and request the pilot's intentions.

1. At a pilot's request, issue a SVFR clearance, if appropriate, when a SVFR letter of agreement exists between an FSS and the control facility. If no agreement exists, request clearance from the control facility. State the aircraft's location and route of flight.

1. If the pilot is operating outside surface area and requests SVFR clearance, issue the clearance or if unable, advise the pilot to maintain VFR outside surface area and to standby for clearance.

1. When an aircraft requests a SVFR clearance to enter surface area during periods of SVFR activity, instruct the pilot to maintain VFR conditions outside surface area pending arrival/recall/departure of SVFR operations.

1. If the pilot is operating inside the surface area and requests an SVFR clearance, advise the pilot to maintain VFR and standby for clearance.

1. Suspend SVFR operations when necessary to comply with instructions contained in subparagraph 4-6-4b or when requested by the control facility.

1. VISIBILITY BELOW ONE MILE

1. When the ground visibility is officially reported at an airport as less than one mile, treat requests for SVFR operations at that airport by other than helicopters as follows:

1. Inform departing aircraft that ground visibility is less than one mile and that a clearance cannot be issued.

1. Inform arriving aircraft operating outside of the surface area that ground visibility is less than one mile and, unless an emergency exists, a clearance cannot be issued.

1. Inform arriving aircraft operating within the surface area that ground visibility is less than one mile and request the pilot's intentions. Relay the pilot's response to the control facility immediately.

1. When weather conditions are not officially reported at an airport and the pilot advises the flight visibility is less than one mile, treat request for SVFR operations at that airport by other than helicopters as follows:

1. Inform departing aircraft that a clearance cannot be issued.

1. Inform arriving aircraft operating outside the surface area that unless an emergency exists, a clearance cannot be issued.

1. Request intentions of arriving aircraft operating within surface areas. Relay the pilot's response to the control facility immediately.

1. Transmit a clearance to scheduled air carrier aircraft to conduct operations if ground visibility is not less than one half mile.
2. Transmit a clearance to an aircraft to fly through surface area if the pilot reports flight visibility is at least one statute mile.

1. PREDESIGNED SPECIAL VFR CLEARANCES

Transmit predesigned SVFR clearances only during those periods authorized by the control facility.

1. Apply these procedures only to aircraft equipped with a functioning two‐way radio. Refer all requests for no‐radio SVFR operations to the control facility.
2. Transmit clearances so that only one aircraft at a time operates in surface area unless:

1. Otherwise authorized by a letter of agreement between the control facility and the FSS.
2. A pilot requests and all pilots agree that they will maintain visual separation while operating in surface area.
