Equivalent airspeed (EAS) is the airspeed at sea level in the International Standard Atmosphere that would produce the same dynamic pressure as the true airspeed (TAS) at the altitude at which the aircraft is flying. In low-speed flight, it is the speed which would be shown by an airspeed indicator with zero error. It is useful for predicting aircraft handling, aerodynamic loads, stalling etc.
