Final answer:
An administrative regulation establishes the maximum length of work shifts for air traffic controllers, enacted by administrative agencies to enforce legislative statutes with executive authority.
Step-by-step explanation:
The rule that establishes the maximum length of work shifts for air traffic controllers is an example of an administrative regulation. Administrative regulations are issued by administrative agencies, which are part of the executive branch of government. These agencies have the authority, delegated from the executive branch, to enact rules that interpret and enforce the statutes passed by the legislative body.
Administrative regulations ensure that bureaucrats follow legislative regulations and procedural guidelines within the scope of their operational duties, as part of the rulemaking process. This rulemaking process usually includes establishing procedural guidelines or standard operating procedures that are necessary for the agencies' functioning and for achieving the intended goals of the respective legislation, such as safety and efficiency in air traffic control.
