Other than potential ground delay/ground stop programs for the normal reasons (weather, volume, etc.), air carrier operations will not be disrupted. There are significant restrictions on general aviation aircraft, including a complete prohibition of VFR flights within 30 miles of DCA, as well as a prohibition of IFR GA flights, except for those to/from IAD, BWI, and HEF (Manassas).
