Section 2. Order Use

POLICY

This order prescribes information necessary to effectively operate and administer air traffic service facilities. When a conflict arises between its provisions and those in other agency issuances, supervisors must request clarification from their respective En Route and Oceanic Operations Area, Terminal Operations Area, or Flight Service Safety and Operations Group. In the event a conflict arises between instructions in this order and the terms of a labor union contract, supervisors must abide by the contract.
