Name a factor that affects pilot performance according to eFIRC.

Stress or fatigue is a significant factor affecting pilot performance due to its impact on cognitive functions, decision-making abilities, and overall physical capacity. When pilots experience high levels of stress or fatigue, their ability to process information, react to unexpected situations, and maintain situational awareness can be severely compromised. This may lead to slower reaction times and impaired judgment, which are critical during flight operations.

Factors like the type of aircraft being flown, weather conditions, and the experience level of the pilot certainly influence performance as well; however, stress and fatigue often manifest regardless of these factors and can be the tipping point that affects a pilot's effectiveness. Recognizing and managing these internal stressors are vital components of maintaining flight safety and optimal performance.
