What are Visual Meteorological Conditions (VMC)?

Visual Meteorological Conditions (VMC) refer to weather conditions in which pilots can operate aircraft primarily by reference to visual cues outside the cockpit. This typically means that visibility is sufficient for pilots to see the ground, other aircraft, and navigational points clearly enough to navigate and control the flight safely without relying solely on instruments.

In VMC, the weather conditions allow for clear visibility, making it possible for pilots to maintain visual separation from obstacles and other traffic. This is crucial for safe visual flight maneuvers, which include straight and level flight, turns, and approaches. The ability to see and visually assess the surroundings enhances situational awareness and minimizes reliance on onboard instrumentation.

The other choices describe scenarios that do not align with the definition of VMC. Instrument navigation is typically required in conditions described in those options, as those would not provide the necessary visual references for a pilot to operate under VMC. Thus, the selection of A as the correct definition accurately captures the essence of VMC and the capabilities it affords pilots.
