Calibration Flights in Washington D.C. area to enhance NORAD response capability

PETERSON AIR FORCE BASE, Colo. – The North American Aerospace Defense Command (NORAD), in coordination with the Federal Aviation Administration and the Department of Homeland Security, will conduct calibration flights June 26-27, 2013 approximately 15 miles southeast of Ronald Reagan National Airport.  

The calibration flights will be performed by a King Air A-90 aircraft flying circular patterns at various altitudes between 2,000 and 17,000 feet above sea level, and will take place between 11:00 pm June 26th and 3:00 am June 27th.  These flights have been carefully planned and will be closely controlled.  The flights are intended to assist in calibration of systems and equipment, and will serve to refine and improve our ability to respond to unknown and potentially threatening aircraft.

If the flights have to be cancelled for any reason, they will be attempted again on 27-28 June 2013 at the same time.

NORAD is the binational Canadian and American command that provides maritime warning, aerospace warning and aerospace control for Canada and the United States.  The command has three subordinate regional headquarters: the Alaskan NORAD Region at Elmendorf Air Force Base, Alaska; the Canadian NORAD Region at Canadian Forces Base Winnipeg, Manitoba; and the Continental NORAD Region at Tyndall Air Force Base, Florida.
