Nerves

Nerves in the body's skin, muscles, and joints send signals to the brain, which, along with other sensory organs, informs the body about its position.

Introduction to Nerves

  • Nerves in the body's skin, muscles, and joints send signals to the brain, which, along with other sensory organs, informs the body about its position.
  • These tactile signals indicate the pilot's current position.
  • The pilot feels acceleration when pushed back into the seat.
    • Often termed "flying by the seat of your pants."
  • Forces created in turns can lead to false sensations of the proper direction of gravity and may give the pilot a false sense of which way is up.
  • Uncoordinated turns, especially climbing turns, send misleading signals to the brain
  • Skids and slips give the sensation of banking or tilting.
  • Turbulence can also create motions that confuse the brain.
  • Pilots need to be aware that fatigue or illness can exacerbate these sensations and ultimately lead to subtle incapacitation.

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

Postural Considerations

  • The postural system sends signals from the skin, joints, and muscles to the brain, which interprets them in relation to the Earth's gravitational pull. [Figure 1]
  • These signals determine posture.
  • Inputs from each movement update the body's position to the brain constantly.
    • Again, "seat of the pants" flying is mainly dependent upon these signals.
  • These sensations, used in conjunction with visual and vestibular clues, can be reasonably reliable.
  • However, due to the forces acting upon the body in certain flight situations, many false sensations can occur when acceleration forces overpower the force of gravity.
  • These situations include uncoordinated turns, climbing turns, and turbulence.
