In aviation, the dial you look at to read your speed through the air is known as an IAS dial (indicated air speed). This dial is an indiaction only, as it works by measuring the amount of air entering the measuring tube (Pito tube); ergo a large head wind (blowing into the front of the aircraft) will give a higher indicated air speed than may actually be true.
