What is the main function of the visual system in aviation?

The main function of the visual system in aviation is to sense position based on visual cues. In the context of flying, pilots rely on their visual system to interpret a wide array of information from the environment. This includes understanding their altitude, speed, direction, and spatial orientation in relation to the aircraft's surroundings. Visual cues such as the horizon, ground patterns, and other aircraft positions are crucial for navigation and safe operation.

The ability to accurately perceive visual information helps pilots make real-time decisions, such as executing maneuvers, maintaining controlled flight, and responding to changes in the environment. The importance of the visual system is underscored by the fact that it provides the primary source of information necessary for piloting an aircraft, especially during critical phases of flight such as takeoff and landing.

In contrast, while detecting changes in weather is an important skill for pilots, it is not the primary function of the visual system; weather detection often relies on instruments and radar as well. Regulating body temperature and maintaining balance during flight are functions related to different systems in the body, such as the thermoregulatory system and the vestibular system, respectively, rather than the visual system specifically.
