Airspace surrounding the presidential retreat in Maryland will expand again this weekend. Pilots are cautioned to check notams before flight. The temporary flight restriction (TFR) will push out to a 10-nm radius below 18,000 feet beginning at 1500 local on Friday, April 11, and continuing through 1600 local on Sunday, April 13.
During the effective times of the notam, practice instrument approaches are prohibited within the TFR.
All operations (except military, law enforcement, and medevac) are prohibited in the 0-5 nm below 12,500 feet. In the 5-10 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. No flight training, aerobatic, glider, parachute, hang gliding, ultralight, aerial application, or animal control operations are permitted.
