Airport Obstruction Charts (OC)
are 1:12,000-scale graphics showing airport obstruction information, FAR Part 77 surfaces, runways, taxiways and apron areas, air navigation facilities, and selected planimetric detail. The OC provides data for computing maximum take-off and landing weights, for establishing instrument approach and departure procedures, for engineering studies relative to obstruction clearance and improvements in airport facilities. An Aeronautical Data Sheet (ADS)-NGS Form 292 is provided at no additional cost with each OC. The ADS includes all aeronautical data the NOAA National Geodetic Survey (NGS) acquires and maintains for airports and NAVAIDs under FAA/NGS Interagency Agreements. It contains all data from the Obstruction Data Sheet (ODS) plus additional information for runways and NAVAIDs. The ADS is available for all OCs published after December 1, 1997. OCs published prior to that date will still include an ODS. A listing of available OCs, the Dates of Latest Editions (OCDOLE), is available on line at: ftp://ftp.ngs.noaa.gov/pub/uddf/info/dole.htm. The OCDOLE is revised quarterly.
