What characterizes a Controlled Taxiway?

A Controlled Taxiway is characterized by regulation and control, which means that operations on this taxiway are managed to ensure safety and efficiency. This type of taxiway typically has specific guidelines governing its use, including restrictions on which vehicles may operate on it and how they must navigate.

In contrast, taxiways that are not regulated or open to all vehicles do not have the same level of oversight, potentially leading to increased risk of accidents or operational conflicts. Furthermore, taxiways reserved exclusively for emergencies would serve a different function, focusing solely on emergency responses rather than regular aircraft or vehicle movement. Thus, the defining aspect of a Controlled Taxiway is its regulated and managed nature, ensuring it operates within established safety parameters.
