Section 14.400 Applicability

This Subpart D applies to aircraft operated in the state of Illinois and the overlying airspace, except for aircraft engaged in special flight operations requiring deviation from this Subpart D that are conducted in accordance with the terms and conditions of a valid certificate of waiver issued by the FAA.  For information on Special Purpose Aircraft and Ultralights, see Subparts I and J respectively.  This Subpart D does not limit the authority of local officials to take appropriate action to stop, prevent or penalize individuals for or from creating a nuisance.  Normal operations, however, do not constitute a nuisance.
