VMC conditions refer to Visual Meteorological Conditions, which are a set of weather criteria used in aviation to indicate that weather conditions are suitable for visual flight. In VMC, pilots can maintain visual reference with the ground and other landmarks, allowing them to fly by visual cues as opposed to relying solely on instruments. This is particularly important for visual flight rules (VFR) operations, where pilots are authorized to navigate and control the aircraft based on visual references outside the cockpit.

VMC is often contrasted with IMC, or Instrument Meteorological Conditions, where visibility is reduced, and pilots must rely on instruments for navigation and control. The definition and criteria for VMC can vary by location and regulations, usually considering factors like horizontal and vertical visibility. Understanding VMC is critical for pilots, as it dictates the conditions under which they can safely operate under VFR.
