The DC FRZ extends approximately 13--15 nmi (15--17 mi; 24--28 km) around the DCA VOR/DME. Flight within the FRZ is restricted to governmental, certain scheduled commercial and a limited set of waivered flights. Three general aviation airports (known as the ``Maryland 3'' or the ``DC 3'') are located inside the DC FRZ: College Park Airport (CGS), Washington Executive/Hyde Field (W32), and Potomac Airport (VKX).
