Overview
V-Speeds are indicated airspeeds that are used for setting specific limitations of an aircraft type. Some V-Speeds are published directly by the manufacturer as an unchanging limitation while other V-speeds may change depending on aircraft configuration or weight. Adherence to all applicable V-speeds is of paramount importance to ensure safety of flight. In most general aviation aircraft, common V-speeds are color-coded into the airspeed indicator for ease of use.
