VMC — Visual Meteorological Conditions — weather good enough for VFR flight.

VMC (Visual Meteorological Conditions) describes weather conditions meeting or exceeding the minimum requirements for VFR flight. The specific VMC minimums vary by airspace class but generally require:

• Visibility of 3 statute miles (5 km) or more
• Distance from clouds: 500 ft below, 1,000 ft above, 2,000 ft horizontally (in controlled airspace)

In Class G airspace below 1,200 ft AGL during daytime, reduced VMC minimums may apply (1 statute mile visibility, clear of clouds). The opposite of VMC is IMC (Instrument Meteorological Conditions).
