    en.wikipedia.org/wiki/Special_visual_flight_rules

    Flight under SVFR is only allowed in controlled airspace, and always requires clearance from air traffic control (ATC). [4] It usually happens when the aircraft is inside controlled airspace, and the local weather is less than the minimums required for flight under visual flight rules (VFR) within the airspace in question.

    If the weather is less than VMC, pilots are required to use instrument flight rules, and operation of the aircraft will be primarily through referencing the instruments rather than visual reference. In a control zone, a VFR flight may obtain a clearance from air traffic control to operate as Special VFR. [2]

    VFR / VMC visibility requirements in the US. In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft.

    en.wikipedia.org/wiki/Airspace_class

    Special visual flight rules: A set of aviation regulations under which a pilot may operate an aircraft. It's a special case of operating under visual flight rules (VFR) where a VFR flight is cleared by air traffic control to operate within a control zone in meteorological conditions that are poorer than visual meteorological conditions. TCA

    In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration 's (FAA) Instrument Flying Handbook defines IFR as: "Rules and regulations established by the FAA to govern flight under ...

The East River Special Flight Rules Area (SFRA), formally known as the East River class-B exclusion, is a section of airspace above the East River in New York City in which flight is permitted under visual flight rules (VFR).

    There are three sets of flight rules under which an aircraft can be flown: Visual Flight Rules (VFR) Special Visual Flight Rules (SVFR) Instrument Flight Rules (IFR) Public transport flights are almost exclusively operated under IFR, as this set of rules allows flight in regions of low visibility (e.g. cloud).
