VMC Versus IMC Flight Conditions

VMC Versus IMC Flight Conditions VMC Versus IMC Flight Conditions VMC and IMC are aviation terms used to describe meteorological conditions during flight. VMC stands for visual meteorological conditions, and IMC stands for instrument meteorological conditions. Although the two terms are often used interchangeably (even, sadly, among industry professionals) with the terms VFR and IFR, respectively, VMC is not the same as VFR, and IMC is not the same as IFR.  The Rules of VFR and IFR As most pilots know, there are two sets of rules for flying any aircraft: VFR and IFR. VFR stands for visual flight rules, which constitute the set of regulations under which a pilot operates an aircraft in weather conditions generally clear enough to allow the pilot to see the aircraft is going. Specifically, the weather must be better than the basic VFR weather allowable in regards to the VMC, the visual meteorological conditions, as specified in the rules laid out by the most relevant aviation authority. The term IFR stands for instrument flight rules.
