What does "aft" refer to on an aircraft?

The term "aft" in aviation refers to the rear section of an aircraft. It is a directional term used to describe parts of the airplane that are located toward the back, opposite of the "fore" or front section. Understanding this terminology is crucial for navigation within the aircraft, especially for cabin crew, to assist passengers and communicate effectively about various locations in the aircraft, such as restrooms, exits, and emergency procedures. In contrast, the other options refer to different sections or orientations of the aircraft, which are not applicable to the term "aft."
