If the weather is good enough, pilots can fly by looking out the window and avoiding hazards. There are some rules involved about how close a pilot can come to clouds, restricted or controlled airspace, and ground structures, and those rules are referred to as visual flight rules. Most small plane flying is conducted under VFR. A pilot might also say that the weather is VFR, meaning that the weather is clear enough that flight under visual flight rules is legal, or that an airport is VFR meaning that the weather at that airport is VFR.
The rules that govern the procedures for conducting flight under visual conditions. abbreviation: VFR Note: The abbreviation “VFR" is used by pilots and controllers to indicate a type of flight plan (FP) or weather conditions. Fr: règles de vol à vue
Set of Federal Aviation Administration (FAA) rules, guidelines, and procedures that apply to aircraft when a pilot is conducting flight with visual reference to the ground.
Rules governing flight during periods of generally good visibility and limited cloud cover. Aircraft flying under VFR are not required to be in contact with air traffic controllers and are responsible for their own separation from other aircraft.
Refers to the general weather conditions pilots can expect at the surface. VFR is ceiling greater than or equal to 1,000 feet and visibility greater than or equal to 3 miles. Marginal VFR (MVFR) is a sub-category of VFR (ceiling 1,000 - 3,000 feet and/or visibility 3 to 5 miles).
Rules that govern the procedures for conducting flight under visual conditions (FAR Part 91).
A regulatory term describing flights that are conducted only in conditions where the pilot can see the ground, or in some instances is flying in the free space above a cloud. Compare to Instrument flight rules.
Rules and procedures specified in FAR Part 91 for aircraft operations under visual conditions. Aircraft operations under VFR are not generally under positive control by ATC.
(Abbreviated VFR.) A set of regulations set down by the U.S. Civil Aeronautics Board (in Civil Air Regulations) to govern the operational control of aircraft during visual flight. The abbreviation VFR is seldom used to denote the regulations themselves, but is popularly used to describe the weather and/or flight conditions to which these rules apply.
Refers to the general weather conditions pilots can expect at the surface. VFR criteria means a ceiling greater than 3,000 feet and greater than 5 miles.
Visual flight rules (VFR) are a set of aviation regulations under which a pilot may operate an aircraft in weather conditions sufficient to allow the pilot, by visual reference to the environment outside the cockpit, to control the aircraft's attitude, navigate, and maintain safe separation from obstacles such as terrain, buildings, and other aircraft.
