TCAS, ADS-B Unreliable on East Coast During September
Airspace affected is over Virginia, North and South Caroline, Georgia and Florida.

ADS-B surveillance and some TCAS operations in the airspace over Virginia, North and South Carolina, Georgia and Florida might become unreliable as of September 2 at 1 a.m. EDT, according to a Notam the FAA issued on September 1. The outages are due to events the agency labeled as “late notice from the Department of Defense of military exercises.” NBAA "voiced its concern to the FAA that these sort of significant impact tests need much more notice to operators in the National Airspace System."
