# Visual Meteorological Conditions **Visual meteorological conditions (VMC)** are required in order to be able to fly under visual flight rules (VFR). If at least one of the minimum values is not met, VFR flights are no longer permitted or must land immediately. In this case, SVFR can be used in control zones under certain circumstances.
