Sec. 169.10  What geographic coordinates are used?

    Geographic coordinates expressed in terms of latitude or longitude, 
or both, are not intended for plotting on maps or charts where the 
referenced horizontal datum is the North American Datum of 1983 (NAD 
83), unless such geographic coordinates are expressly labeled NAD 83. 
Geographic coordinates without the NAD 83 reference may be plotted on 
maps or charts referenced to NAD 83 only after application of the 
appropriate corrections that are published on the particular map or 
chart being used.
