In addition to checking NOTAMs before flight, Aeronautical Information Circulars can provide useful guidance in advance describing notified Restricted Airspace (Temporary). Pilots are respectfully reminded that the regulations usually preclude access to the restricted airspace without express permission. In each case, the RA(T) notification will describe the detail of the restriction including dimensions and timing.
