Special flight rules area
In United States aviation, a special flight rules area (SFRA) is a region in which the normal regulations of flight do not apply in whole or in part, especially regulations concerning airspace classification, altitude, course, and speed restrictions, and the like.
Washington, DC Special Flight Rules Area
Following the terrorist attacks of September 11, 2001, the airspace around Washington DC underwent a number of changes designed to restrict flying around the city. In 2003, a temporary flight rules area was created and was named the Washington DC Air Defense Identification Zone. In 2008 the temporary status of the ADIZ was removed and the rule was made permanent.
In order to fly within the DC SFRA, pilots of general aviation aircraft are required to file a special fight rules flight plan, obtain a discrete transponder code, and remain in contact with air traffic control at all times. Special training is required in order to fly within 60 nm of the Washington DC (KDCA) VOR.
Other examples of SFRAs include:
- Grand Canyon
- Ketchikan, Alaska
- Valparaiso, Florida
- Surrounding Los Angeles International Airport
- Within the Class C airspace of Anchorage International Airport and Elmendorf AFB
On November 19, 2009, the FAA effected an SFRA in the New York City Class B airspace, motivated largely by the mid-air collision of a private general avaiation aircraft and a sightseeing helicopter ride along the Hudson River VFR corridor in the summer of 2009.,
