Air pockets are areas in a fluid, like water or air, where there is little to no movement, creating a space filled with air. These pockets can form in various situations, such as when a plane flies through turbulent air, causing sudden drops or rises. In water, air pockets can occur when bubbles are trapped beneath the surface. In aviation, air pockets are often referred to as turbulence, which can be caused by weather conditions or changes in air pressure. Pilots are trained to handle these situations, ensuring passenger safety during flights. Understanding air pockets helps in recognizing their impact on travel and safety.
