The Cape TRACON ASR-8 surveillance radar will be out of service from Oct. 13 until March 13, 2016, the FAA announced. Backup systems, the Nantucket ASR-9 and the Boston Center Radar Presentation off the North Truro radar site (CENRAP), will cover the TRACON's airspace during the outage. Radar coverage provided by the backup systems will affect operations in the Cape TRACON airspace. Pilots can expect increased separation between aircraft, limited services to all aircraft and the potential for limited approvals for practice instrument approaches. Also, traffic advisories will not be available to aircraft not equipped with transponders or, in some areas, those flying below 2,000 feet.
