In aviation, visual flight rules (VFR) is a set of regulations under which a pilot operates an aircraft in weather conditions generally clear enough to allow the pilot to see where the aircraft is going.
Visual flight or visual attitude flying is the control of an aircraft via outside references (such as the sky or the runway in takeoff). [1] For aircraft, the primary visual reference used is usually the relationship between the aircraft's "nose" or cowling against the natural horizon .
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.
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.
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 US rules require the aircraft to be fitted with the instruments required for IFR flight, [3] and student pilots [4] and sport pilots [5] must maintain visual reference with the surface. Other operations (such as commercial, turbine powered, and fractional ownership) include special limitations.
NTSB Chairman Robert Sumwalt: “He was flying under Visual Flight Rules - or VFR - which legally prohibited him from penetrating the clouds. However, as we've seen in so many accidents, this ...
Flight rules are regulations and procedures adopted for flying aircraft in various conditions. Flight rule regimes include: Instrument flight rules, regulations and procedures for flying aircraft by referring only to the aircraft instrument panel for navigation; Special Needs, a set of aviation regulations under which a pilot may operate an ...
