It may chart such airways system and arrange for publication and distribution of such maps and charts and notices and bulletins relating to such airways as may be required in the public interest. The system shall be supplementary to and coordinated in design and operation with the federal airways system. It may include all types of air navigation facilities, whether publicly or privately owned, if such facilities conform to federal safety standards.
