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

penalize individuals for or from creating a nuisance. Normal operations,
however, do not constitute a nuisance.
