Flying with a cold can lead to spatial disorientation: if the pressure equalises in one ear but NOT the other, this can cause different stimulations in the inner ear, leading to dizziness and vertigo.

Aerodontalgia barotrauma is frequently associated with colds: swelling of soft tissues around the teeth prevents the exchange of gas, causing pain. The areatest risk is during rapid climbs at low altitudes.

Sinus barotrauma can be very painful, distracting the pilot from flying: if the paranasal sinuses fall to equalisepressure. hearing can be impaired. This most frequently occurs in the climb at low altitudes.

Otic barotrauma can be very painful, distracting the pilot from flying: it can result in ruptured ear drums, and most frequently occurs in the climb at high altitudes.
