Special VFR
Special visual flight rules permit visual operations at less than standard requirements when certain circumstances permit.
Introduction to Special VFR
- Pilots operate under either Visual or Instrument Flight Rules.
- As weather conditions deteriorate from visual to instrument meteorological conditions (IMC) however, pilots may find themselves in areas which legally require Instrument Flight Rules (IFR), but where navigation can still be accomplished visually.
- Within qualifying controlled surface areas, pilots may have another option, Special VFR (Visual Flight Rules) (SVFR).
- SVFR (Special Visual Flight Rules) operations may be authorized for aircraft operating in or transiting a Class B, Class C, Class D, or Class E surface area when the primary airport is reporting VFR but the pilot advises that basic VFR cannot be maintained.
- Provided that certain requirements are met, pilots may request their Special VFR clearance from Air Traffic Control (ATC).
- A special VFR clearance is never a given and in fact some exceptions do exist
- Reinforce your understanding of Special VFR by completing the knowledge quiz and interactive scenario, comparing your performance with the applicable Airman Certification Standards, and reviewing the topic summary before moving on.
Special VFR Key Highlights
- Special VFR (SVFR) operations allow aircraft to operate within controlled surface areas when weather conditions are below basic VFR minimums.
- SVFR operations require an ATC clearance and are generally limited to operations clear of clouds with at least one statute mile flight visibility.
- Special VFR operations are commonly conducted within Class B, C, D, or E surface areas surrounding airports.
- Night SVFR airplane operations require an instrument-rated and current pilot and an aircraft equipped for IFR flight.
- Pilots remain responsible for terrain clearance, obstacle avoidance, and seeing and avoiding other aircraft during SVFR operations.
- Reduced visibility and limited visual references can increase pilot workload and operational risk during Special VFR operations.
- ATC may deny Special VFR requests based on traffic volume, IFR operations, weather conditions, or operational limitations.
- Certain airports prohibit fixed-wing Special VFR operations due to airspace complexity or operational safety considerations.
- Pilots should evaluate weather trends, terrain, aircraft capability, and personal proficiency carefully before requesting SVFR clearance.
- Understanding Special VFR operations improves regulatory compliance, weather decision-making, and overall flight safety.
Flight Rules and Meteorological Conditions
- To operate under Visual Flight Rules without a Special VFR clearance, the pilot must satisfy the visibility, cloud-clearance, and any surface-area ceiling requirements applicable to the airspace
- In addition to operating within VMC conditions, pilots must maintain specific distances from clouds, depending on airspace. []
- Whether conditions permit basic VFR depends on the visibility, cloud-clearance, and surface-area requirements applicable to the airspace. A 1,000-foot ceiling and 3 statute miles visibility are not universal definitions of VMC or IMC.
- Special VFR, or SVFR, allows an eligible pilot to operate under VFR within qualifying controlled surface airspace when the weather is below the basic VFR requirements for that surface area, provided the pilot receives an ATC clearance and complies with 14 CFR 91.157.
- Instead of the basic VFR minimums in 91.155, eligible operations may use the requirements below when below 10,000 feet MSL (Mean Sea Level) and within the upward extension of the lateral boundaries of controlled airspace designated to the surface for an airport.
- Flight rules and meteorological conditions are related but are not interchangeable. A pilot may operate under VFR only when all applicable VFR requirements are satisfied or when an authorization such as Special VFR applies.
Special VFR Requirements
- Special VFR must be specifically requested by the pilot. Some requirements differ between fixed-wing aircraft and helicopters.
-
Fixed Wing Requirements:
-
Day Considerations:
- Operations performed under Part 91
- Obtain an ATC clearance before beginning the Special VFR operation within the qualifying surface area.
- Maintain clear of clouds
- At least 1 statute mile flight visibility.
-
Night Considerations:
- For airplane operations between sunset and sunrise, or in Alaska when the sun is more than 6° below the horizon, the daytime requirements apply, plus:
-
- The person being granted the clearance must meet the applicable requirements for instrument flight under Part 61.
- The airplane must be equipped as required by 91.205(d).
-
Takeoff and Landing:
- Ground visibility must be at least 1 statute mile when ground visibility is reported.
- If ground visibility is not reported, flight visibility must be at least 1 statute mile.
- For the purposes of this paragraph, the term flight visibility includes the visibility from the cockpit of an aircraft in takeoff position if:
- The flight is conducted under Part 91; and
- The airport at which the aircraft is located is a satellite airport that does not have weather reporting capabilities.
- The determination of visibility by a pilot is not an official weather report or an official ground visibility report.
- For the purposes of this paragraph, the term flight visibility includes the visibility from the cockpit of an aircraft in takeoff position if:
-
-
Rotary Wing Requirements:
- Helicopters are afforded certain exceptions that fixed-wing are not:
- The additional nighttime instrument-flight qualification and aircraft-equipment requirements in 91.157(b)(4) do not apply to helicopters.
- Helicopters must remain clear of clouds and may operate in Class B, Class C, Class D, and Class E surface areas with less than 1 statute mile visibility.
- Helicopters are afforded certain exceptions that fixed-wing are not:
SVFR Clearances
- An ATC clearance must be obtained prior to operating within a Class B, Class C, Class D, or Class E surface area when the weather is less than that required for VFR flight.
- When an operating control tower serves a Class B, Class C, or Class D surface area, request the clearance from that tower. For a Class E surface area, the AIM identifies the nearest tower, Flight Service, or center. Use current published contact information and verify that the controlled surface area is in effect.
- The pilot must request the clearance; ATC may authorize Special VFR only upon the pilot's request.
- A VFR pilot may request and be given a clearance to enter, leave, or operate within most Class D and Class E surface areas and some Class B and Class C surface areas in special VFR conditions, traffic permitting, and providing such flight will not delay IFR operations.
- It is not necessary to file a complete flight plan with the request for clearance, but pilots should state their intentions in sufficient detail to permit ATC to fit their flight into the traffic flow
- The clearance will not contain a specific altitude as the pilot must remain clear of clouds.
- The numerical basic-VFR cloud-distance requirements are replaced by the requirement to remain clear of clouds.
- No numerical cloud distance is specified, but the pilot should preserve enough margin to remain clear as conditions change.
- The controller may require the pilot to fly at or below a certain altitude due to other traffic, but the altitude specified will permit flight at or above the minimum safe altitude.
- In addition, at radar locations, flights may be vectored if necessary for control purposes or on pilot request.
- The pilot remains responsible for terrain and obstacle clearance. Section 91.119 permits operations below its otherwise applicable minimum altitudes only when necessary for takeoff or landing.
- "Cleared [to enter/out of/through], [airport] surface area (and if required) [direction] of [airport], [routing], and maintain special v-f-r conditions (and if required), at or below [altitude below 10,000 feet MSL], cleared for [arrival/departure procedure], cleared for [coded arrival or departure procedure] arrival/departure, (additional instructions as required)"
Priority
- ATC provides separation between Special VFR aircraft and between Special VFR and IFR aircraft within the authorized surface area.
- ATC does not provide separation after an aircraft leaves the Class B, Class C, Class D, or Class E surface area on a special VFR clearance.
- SVFR flights may be approved only if arriving and departing IFR aircraft are not delayed.
- The priority afforded IFR aircraft over SVFR aircraft however, is not intended to be so rigidly applied that inefficient use of airspace results.
- The controller has the prerogative of permitting completion of a SVFR operation already in progress when an IFR aircraft becomes a factor if better overall efficiency will result.
- ATC will inform an aircraft of the anticipated delay when a SVFR clearance cannot be granted because of IFR traffic
- "Expect [number] minute delay, (additional instructions as necessary)"
Non-Towered/Closed Airports
- First determine whether a controlled surface area remains in effect. If it does, request Special VFR from the appropriate ATC facility using current published contact information. For a Class E surface area, the AIM identifies the nearest tower, Flight Service, or center. A tower closure does not itself waive a required clearance or determine the current airspace classification.
- Pilots arriving or departing an uncontrolled airport that has automated weather broadcast capability (ASOS/AWOS) should monitor the broadcast frequency, advise the controller that they have the "one-minute weather" and state intentions prior to operating within the Class B, Class C, Class D, or Class E surface areas.
- When requesting Special VFR at an airport without reported weather, advise ATC that VFR cannot be maintained and report your flight visibility.

Special VFR Conclusion
- During the daytime period specified by 91.157, airplane Special VFR does not itself require the pilot to meet Part 61 instrument-flight requirements or the airplane to be equipped under 91.205(d). Outside that period, both requirements apply.
- Special VFR may be available to an eligible pilot operating within the privileges and limitations of that pilot's certificate
- It can support a legal transition through a qualifying surface area, but low visibility, clouds, terrain, and changing weather can still make the operation unsafe.
- ATC may authorize Special VFR only when the pilot requests it.
- At the end of the day, however, just because you can do something doesn't mean you should
- Always maintain your personal minimums regardless of what the regulations say you can do
- Special VFR applies only within the lateral boundaries of the qualifying controlled surface area and below 10,000 feet MSL. After leaving that surface area, the pilot must comply with the rules and weather minimums applicable to the subsequent airspace.
- Use Special VFR with caution, especially at night
- Outside the daytime period specified by 91.157, the person receiving an airplane clearance must meet applicable Part 61 instrument-flight requirements, and the airplane must be equipped under 91.205(d).
