Which of the following features is most likely found in a synthetic vision system?

A synthetic vision system (SVS) primarily provides pilots with a visual representation of the environment in which they are flying. This includes a computer-generated display of terrain, obstacles, and other critical flight path information, allowing for enhanced situational awareness. By projecting a three-dimensional view of the surroundings, an SVS improves a pilot's ability to navigate and manage potential hazards, especially in low visibility conditions.

Visual depiction of terrain is an integral part of synthetic vision technology, as it helps pilots to understand their altitude relative to the ground, identify geographic features, and assess surrounding terrain for obstacles during both visual flight and instrument approaches. The focus of an SVS is on visualizing data in a way that makes it easier for pilots to interpret their flight environment, enhancing safety and operational efficiency.

Other features mentioned, such as historical flight data, automatic flight control, and passenger communication systems, do not directly pertain to the synthetic vision concept. Historical flight data typically relates to log information for flight analyses, automatic flight control pertains to managing the aircraft's trajectory, and passenger communication systems focus on communication aspects unrelated to visual and situational awareness critical to flying safely. Thus, visual depiction of terrain clearly stands out as the feature characteristic of a synthetic vision system.
