Motion Sickness

Motion sickness, also known as airsickness, is caused by the brain receiving conflicting messages about the body's position and movement.

Introduction to Motion Sickness

  • Motion sickness, also known as airsickness, is caused by the brain receiving conflicting messages about the body's position and movement.

  • WARNING:
    All aeromedical topics are GENERALIZED.
    Always consult with a doctor or physician to understand your specific situation.

    Motion Sickness Key Highlights

    • Motion sickness occurs when conflicting sensory signals disrupt the body’s perception of movement and orientation.
    • Turbulence, unusual aircraft maneuvers, heat, stress, anxiety, and poor ventilation can contribute to motion sickness during flight.
    • Symptoms commonly include nausea, dizziness, sweating, fatigue, disorientation, and decreased concentration.
    • Motion sickness can impair pilot performance, situational awareness, and aeronautical decision-making abilities.
    • Pilots may reduce motion sickness risk by maintaining visual reference with the horizon and minimizing unnecessary head movement.
    • Proper ventilation, hydration, rest, and gradual exposure to flight conditions can help improve tolerance to motion sickness.
    • Fatigue, dehydration, illness, and stress may increase susceptibility to motion sickness symptoms.
    • Some motion sickness medications can cause drowsiness or cognitive impairment that may make them unsafe for flight operations.
    • Pilots experiencing significant motion sickness should transfer aircraft control or terminate the flight if safety is affected.
    • Understanding motion sickness improves physiological awareness, risk management, and overall flight safety.

    Motion Sickness

    • Motion sickness, also known as airsickness, is caused by the brain receiving conflicting messages about the body's position and movement.
      • A pilot may experience motion sickness during initial flights, but it generally goes away within the first few lessons.
      • Anxiety and stress, often experienced at the beginning of flight training, can contribute to motion sickness.
      • Symptoms of motion sickness include general discomfort, nausea, dizziness, paleness, sweating, and vomiting.
    • It is important to remember that experiencing airsickness is no reflection on one's ability as a pilot.
      • If you are prone to motion sickness, inform the flight instructor so they can use techniques to help you overcome it.
      • For example, avoid lessons in turbulent conditions until you become more comfortable in the aircraft, or start with shorter flights and gradually progress to more extended instruction periods.
      • If symptoms of motion sickness are experienced during a lesson, opening fresh air vents, focusing on objects outside the airplane, and avoiding unnecessary head movements may help alleviate some of the discomfort.
      • Although medications like Dramamine can help prevent airsickness in passengers, they are not recommended for use during flights, as they can cause drowsiness and other side effects.

    Motion Sickness Prevention

    • Before being forced to attempt to cure motion sickness or end a flight early, pilots can prevent motion sickness.
    • Prevention techniques include smooth flying (slow coordinated inputs), avoiding flight on a turbulent day, drinking water, only eating a light, plain meal before flying, and coaching passengers through what they could expect.

    Remediation of Motion Sickness

    • Drinking water, while also a preventive measure, can help ease the effects of motion sickness.
    • Flying straight and level or minimizing maneuvers for as long as possible can relieve any vertigo-type sicknesses.
    • Putting a cool rag around the neck can reduce nausea.
