The FAA develops engineering, design, and construction standards for civil airports, heliports, and seaplane bases. This includes standards for airfield pavement; airport lighting, marking, signs, and other visual aids; safety during construction; surveying and GIS data; deicing, ARFF, and other facilities; bird radar and foreign object detection systems; and more.
