Which term refers to the rear section of an aircraft?

The term that refers to the rear section of an aircraft is "AFT." In aviation terminology, "AFT" is used to describe the sections and components located towards the back of the aircraft. Understanding this terminology is essential for clear communication among crew members and when discussing aircraft design and layout, as it helps in identifying specific areas, such as the fuselage and the cabin.

The other terms have specific meanings that refer to different aspects of the aircraft. "Fore" describes the front part of the aircraft, "Starboard" indicates the right side when facing forward, and "Port" refers to the left side. Each of these terms is crucial for navigation and aircraft orientation but does not pertain to the rear section, making "AFT" the correct choice in this context.
