27 The most comprehensive information on a given airport is provided by
A. the Chart Supplements U.S. (formerly Airport Facility Directory).
A/FD (Airport/Facility Directory) is now known as the Chart Supplement (CS). You can download it in PDF format, but it is a massive- 243Mb. The same information is available in private sector sources. My favorite source of airport information is AirNav, but the FAA-CS is the official airport and facility reference document.
This is correct.
