Why Does a Plane Drop Suddenly?

When an aircraft experiences turbulence, the plane can drop or change altitude suddenly. This is why pilots always caution passengers to buckle up and stay seated when they are experiencing flight turbulence. The sudden movements put passengers at risk.

Why do planes suddenly drop at altitude?

One likely reason for the sudden drop is a pocket of turbulence, colloquially referred to as an 'air pocket'. In a nutshell, an air pocket is a region of low pressure causing an aircraft to lose height suddenly. Air pockets are just an extreme form of turbulence where a downdraft causes the aircraft to drop suddenly.

What causes an airplane to fall?

Aviation accidents can be traced to a variety of causes, including pilot error, air traffic controller error, design and manufacturer defects, maintenance failures, sabotage, or inclement weather.
