The FAA has issued a notam that expands a temporary flight restriction area (TFR) around the presidential retreat at Camp David, Maryland. The TFR, centered on Prohibited Area P-40, will extend to a 10-nm radius below 18,000 feet beginning at 8:45 a.m. local on Saturday, December 21, and continue through 9:15 a.m. local on Thursday, December 26. All operations (except military, law enforcement, and air ambulance) are prohibited in the 0- to 5-nm ring below 12,500 feet. In the 5- to 10-nm ring, aircraft must be on an active IFR or VFR flight plan with a discrete transponder code assigned by air traffic control and must maintain radio contact with ATC. All such flights must be for ingress, egress, or transit only. During that time, the notam prohibits practice instrument approaches within the TFR. No flight training, aerobatic, glider, parachute, hang gliding, ultralight, aerial application, or animal control operations are permitted. See the notam ( http://www.aopa.org/whatsnew/newsitems/2001/010915tfr.html#2/2927 ) or a graphic ( http://www.aopa.org/images/whatsnew/newsitems/2002/notams/2-1730.jpg ). AOPA warns pilots that this restricted airspace will be actively enforced by the military and violators will be intercepted and forced to land. AOPA strongly encourages pilots to obtain a full briefing and check for new or modified TFRs before each flight. [Unable to display image]
