Instrument Flight Rules (IFR)
The rules which apply when flying by means of reference to the instruments in the cockpit
Special VFR Rules (SVFR)
The rules for operating in weather conditions that are less than VFR within a control zone where some aircraft are permitted flight under visual flight rules
Visibility
The ability as determined by atmospheric conditions and expressed in units of distance, to see and identify prominent unlit objects by day and prominent light objects by night
Ceiling
The lowest height at which a broken or overcast condition exists, or the vertical visibility when obscured condition such as snow, smoke or fog.
