What is vmc in aviation?

VMC stands for Visual Meteorological Conditions and refers to a set of specific weather conditions that allow pilots to operate an aircraft visually, without relying on instruments. In aviation, VMC is defined as weather conditions equal to or greater than the minimum visibility and ceiling values specified by regulatory authorities.

Pilots must be able to maintain a positive visual reference with the ground and surrounding objects, as well as be able to see other aircraft in the area. VMC is required for most general aviation flights, as well as for takeoff, approach, and landing of commercial aircraft.

In summary, VMC is a key factor in determining whether a flight can be made safely, and pilots must be trained to quickly recognize and adapt to changing weather conditions in order to operate within VMC.
