The first known reference to the term "cockpit" comes from the rather barbaric sport of cockfighting and refers to the pit in which the fights occurred. Shortly thereafter, the word naturally attained a connotation as being related to any scene of grisly combat, such as European battlefields. By the end of the 16th Century, the term was being used to describe sunken pits or cramped, confined spaces. In particular, the word cockpit was used to describe the pit around the stage in a theater containing the lowest level of seats, as illustrated by this passage from William Shakespeare's "Henry V."
Can this Cock-Pit hold
The vastie fields of France? Or may we cramme
Within this Woodden O, the very Caskes
That did affright the Ayre at Agincourt?

In so doing, Shakespeare may have been trying to draw an analogy between the spectacle of a cockfight or battle and that of a theatrical performance. An entire London theater even became known as The Cockpit in 1635, ...more

The more direct linkage to your question comes from the use of the term cockpit to refer to a compartment belowdecks on a British naval vessel beginning around 1700. The often cramped and confined compartment was placed below the waterline and served as quarters for junior officers as well as for treating the wounded during battle. Although the purpose of this compartment evolved over time, it's name did not. Even today, a room on the lower deck of a yacht or motor boat where the crew quarters are located is often called a cockpit. In addition, the rudder control space from which a vessel is steered is sometimes called a cockpit since a watchman in the highest position is called a cock, and a cavity in any vessel is called a pit.

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 becam ...more

Cockpit as a term for the pilot's compartment in an aircraft first appeared in 1914. From about 1935 cockpit also came to be used informally to refer to the driver's seat of a car, especially a high performance one, and this is official terminology in Formula One. The term is most likely related to the sailing term for the coxswain's station in a Royal Navy ship, and later the location of the ship's rudder controls.
On an airliner, the cockpit is usually referred to as the flight deck. This term derives from its use by the RAF for the separate, upper platform where the pilot and co-pilot sat in large flying boats.
