Notice of the existence of a state of military emergency and of currently prevailing air traffic control requirements issued to the Department and to civil and military aviation facilities of this State over the Federal Interstate Airways Communications System and the State emergency fan-out system components of the Civil Air Defense Warning Net is sufficient to authorize the Department to control non-scheduled civil aircraft movement as provided in this Act.
The Department may utilize, to the extent of capacity, the radio network system of the Illinois State Police, county sheriffs' offices and municipal police departments in order to assure a reliable and adequate State fan-out communications system required for rapid dissemination of notices to airmen and civil aviation authorities respecting such aircraft movement control as may be required on the part of the Department and airport operators and managers during the existence of a state of military emergency.
