Who is referred to as the Captain in aviation?

In aviation, the term "Captain" specifically refers to the pilot in command of the flight. This individual holds ultimate responsibility for the operation of the aircraft and the safety of everyone on board, including passengers and crew. The Captain is tasked with making critical decisions related to flight operations, navigating, and overseeing the conduct of the flight and the aircraft's performance.

The Captain's role is vital, as they are trained to handle various situations, including emergencies, and have the authority to make final determinations regarding the flight's course, both in normal and adverse conditions. They are also responsible for communicating with air traffic control and coordinating with the co-pilot and cabin crew to ensure a safe flying experience.

In contrast, the chief flight attendant is responsible for the cabin crew and passenger service but does not control the aircraft. The co-pilot assists the Captain and can fly the aircraft but is not the one in command. The ground control operator is involved in coordinating air traffic on the ground but has no authority over the aircraft once it is airborne.
