Which condition can affect a pilot's situational awareness during a flight?

Situational awareness is the perception of environmental elements in time and space, understanding their meaning, and projecting their status in the near future. Pilot fatigue significantly impairs this awareness by affecting cognitive function, reaction times, and decision-making capabilities. When a pilot is fatigued, their ability to process information and recognize changes in the cockpit or surrounding environment diminishes.

Fatigue can lead to confusion, decreased vigilance, and impaired judgment, making it challenging for a pilot to remain aware of critical flight data and external conditions. It can also result in slower response times and an increased likelihood of missing important cues or warnings, thereby compromising safety. By recognizing and addressing fatigue, pilots can better maintain their situational awareness and ensure a safer flight.
