Ahead of the curve is an idiom that is most probably derived from the military. We will examine the definition of the phrase ahead of the curve, where it came from and some examples of its use in sentences.

To be ahead of the curve is to be more advanced or modern than someone or something else, to be on the forefront of a trend, to get a jump-start on a craze or idea and to act upon it before others do. The phrase ahead of the curve may also mean to be above average in some way. The idiom ahead of the curve is an abbreviation of the expression ahead of the power curve. This renders a clue as to the origin of the term. The power curve is an aviation term which means the interaction between drag and airspeed, or how the engine power of a given aircraft acts upon that aircraft’s airspeed. The mathematics of the power curve may be plotted in a curve. When discussing the amount of power a pilot must ask of his aircraft engine in order to maintain speed and altitude, pilots may talk about being ahead of the power curve or maintaining good speed and altitude, or being behind the power curve in which case they lose speed and altitude. The idiom ahead of the power curve came into use in the 1920s, when more airplanes took to the skies. The idiom was shortened in the 1960s and 1970s to the phrase ahead of the curve, and was popularized by the Nixon administration.

The phrase ahead of the curb is an eggcorn, which is a misheard word or phrase that maintains its original meaning. Ahead of the curb is a fairly common mistake but it is incorrect, and should never be used.
