What defines a "movement area" at an airport?

A "movement area" at an airport is defined as any area under the control of the Air Traffic Control Tower (ATCT) where aircraft are permitted to taxi, take off, and land. This includes runways and taxiways that allow aircraft to move safely within the airport environment while minimizing the risk of accidents or unauthorized access. The ATCT oversees this area to manage aircraft movements effectively and ensure security and safety protocols are followed.

The distinction is important because it differentiates active operational zones from other areas that may not have the same level of control or requirement for clearance, such as parking areas or terminals meant for passenger waiting. Understanding the concept of the movement area helps ensure that those operating within an airport - pilots, ground crew, and other personnel - are aware of the designated spaces where they can safely conduct their activities related to powered flight operations.
