Dip

nounShop talkAviation

A sudden, brief loss of altitude during flight, often caused by a downdraft.

A dip is a momentary drop in altitude experienced during flight. It typically happens when an aircraft flies through a pocket of descending air or a sudden change in wind shear. While passengers often perceive it as an air pocket, pilots recognize it as a standard atmospheric disturbance that the aircraft will naturally fly out of as it regains normal airflow over the wings.
