"VMC" redirects here. VMC may also refer to Visual meteorological conditions.V speeds (aircraft) are speeds that define certain performance and limiting characteristics of an aircraft and the "V" stands for velocity. They are established by the manufacturer during design and testing, and are specific to the aircraft model. Usually "V speeds" are relative to the air through which the aircraft is moving and are thus airspeeds. In many cases, they are defined by reference to the standard atmosphere or other specific conditions, and/or at the aircraft's maximum gross weight, and the pilot is responsible for calculating the effective value based on the actual weight and air density. In other cases the indicated airspeed, the value uncorrected for atmospheric pressure differences (height and temperature), is useful directly by the pilot. E.g. the indicated stall speed V_S remains essentially constant for all heights and temperatures while the true stall speed increases as pressure lessens.
