Which of the following is a symptom of motion sickness in a cockpit?

Motion sickness in a cockpit is characterized by symptoms such as nausea and dizziness. This occurs because the brain receives conflicting signals from the inner ear (which helps with balance), the eyes, and the deeper body parts regarding motion. In a cockpit, rapid movements, changes in altitude, or turbulent conditions can exacerbate this conflict, leading to these unpleasant sensations. Pilots need to manage these symptoms effectively since they can impair performance and decision-making during flight. Increased alertness, heightened visual acuity, and improved coordination are not typical responses to motion sickness; rather, they suggest optimal functioning of the pilot, which is the opposite of what occurs in cases of motion sickness.
