Visual Flight Rules

Visual Flight Rules

Visual flight rules (VFR) are 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. Specifically, the weather must be better than basic VFR weather minima, i.e. in visual meteorological conditions (VMC), as specified in the rules of the relevant aviation authority. The pilot must be able to operate the aircraft with visual reference to the ground, and by visually avoiding obstructions and other aircraft.

If the weather is below VMC, pilots are required to use instrument flight rules, and operation of the aircraft will primarily be 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.

Famous quotes containing the words visual, flight and/or rules:

    “Nowadays people’s visual imagination is so much more sophisticated, so much more developed, particularly in young people, that now you can make an image which just slightly suggests something, they can make of it what they will.”
    —Robert Doisneau (b. 1912)

    “It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy’s edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create “one world.” Instead of one world, we have “star wars,” and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet’s dead.”
    —Gore Vidal (b. 1925)

    “There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
    —H.L.A. (Herbert Lionel Adolphus)
