PILOT'S VERTIGO

Vertigo is the sensation of spatial disorientation when the surroundings appear to whirl dizzily. It can cause loss of balance, nausea, and vomiting.

Vertigo develops when a person experiences a mismatch between spatial information from the eyes, vestibular system, and proprioceptors. Your senses are tricked, so they deliver conflicting information to the central nervous system. Vertigo does not develop in a sensory organ but in the CNS, which cannot make sense of the combination of sensory inputs. Head movements should be minimised to allow the brain to readjust to the actual spatial situation without causing additional confusion.
  • Under VMC, the horizon is a reference the pilot can trust. There is only one action that will overcome vertigo upon entering IFR conditions. The pilot must immediately transition to flight instruments to determine the aircraft’s attitude and respond accordingly to maintain aircraft control. Body feedback will be wrong and only by reference to the aircraft instruments can safe control of the aircraft be maintained.
