The FAA is leading a public outreach campaign to promote safe and responsible use of unmanned aircraft systems. They are offering a free digital toolkit with outreach materials to federal, state, and other partners to educate unmanned aircraft operators that flying in certain areas is prohibited. This toolkit includes No Drone Zone signage for any medium, including print and web.
The National Capital Region is governed by a Special Flight Rules Area (SFRA) within a 30-mile radius of Ronald Reagan Washington National Airport, which restricts all flights in the greater DC area.
The SFRA is divided into a 15-mile radius inner ring and a 30-mile radius outer ring.
The airspace around Washington, D.C. is more restricted than in any other part of the country. Rules put in place after the 9/11 attacks establish "national defense airspace" over the area and limit aircraft operations to those with an FAA and Transportation Security Administration authorization. Violators face stiff fines and criminal penalties.
