cockpit. n. 1. (Aeronautics) the compartment in a small aircraft in which the pilot, crew, and sometimes the passengers sit. Compare flight deck 1. 2. (Motor Racing) the driver's compartment in a racing car.
This sense of the word, as an often confined space used for control purposes, was first applied to an aircraft around 1914 by pilots during World War I. In keeping with this same meaning, the tightly confined control space of a racing automobile also became known as a cockpit by about 1935.
