Motion sickness

Nausea, dizziness, cold sweat and pale skin when the balance organ in the inner ear senses motion the eyes don’t see, or the other way round: in turbulence, in steep turns, or while reading a chart with the head down. It often comes with spatial disorientation. Look outside at the horizon, keep the head still, get fresh air and fly smooth control inputs. Medication against it can make you drowsy: don’t fly on it without asking an aeromedical examiner.
