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).
FAA's Instrument Flying Handbook defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals. It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan.

Famous quotes containing the words instrument, flight and/or rules:
“We ought, says Kant, to become acquainted with the instrument, before we undertake the work for which it is to be employed; for if the instrument be insufficient, all our trouble will be spent in vain. The plausibility of this suggestion has won for it general assent and admiration.... But the examination can be only carried out by an act of knowledge. To examine this so-called instrument is the same as to know it.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“Fear of error which everything recalls to me at every moment of the flight of my ideas, this mania for control, makes men prefer reason’s imagination to the imagination of the senses. And yet it is always the imagination alone which is at work.”
—Louis Aragon (1897–1982)
“Retaliation is related to nature and instinct, not to law. Law, by definition, cannot obey the same rules as nature.”
—Albert Camus (1913–1960)
