Telecommunication. Part17:Construction, marking, and lighting of antenna structures. Subpart C:Specifications for Obstruction Marking and Lighting of Antenna Structures . Section17.22:Particular specifications to be used.
Whenever painting or lighting is required, the Commission will generally assign specifications in accordance with the FAA Advisory Circulars ref- erenced in § 17.23. If an antenna instal- lation is of such a nature that its painting and lighting in accordance with these specifications are confusing, or endanger rather than assist airmen, or are otherwise inadequate, the Commission will specify the type of paint- ing and lighting or other marking to be used in the individual situation.
