Not sure what to make of this "notice?"" It's termed "a late notice Department of Defense exercise" due to Military exercises.

According to the information (if I'm reading it clearly?) that this (month long) Military exercise may make the Traffic Collision Avoidance System unreliable in the airspace over several States and up to 200 nautical miles offshore? There are a lot of important events scheduled for September, including the Pope's visit. I would imagine, there's a lot of dignitaries flying in, especially for the U.N. events. Why would the Military compromise air space surveillance?

TCAS - Traffic Collision Avoidance System

Due to military activities, the TCAS and ADS-B surveillance may be unreliable in the airspace over Virginia, North Carolina, South Carolina, Georgia and Florida, and extending approximately 200 nautical miles offshore, from 1 a.m. EDT (0500z) Sept. 2 until midnight EDT (0459z) on Oct. 1.

Pilots are advised that the traffic alert and TCAS may fail to establish tracks on nearby aircraft and may fail to receive traffic alerts (TA) or resolution advisories (RA). Operators should be aware that tracks may first appear within close proximity to their aircraft, and may immediately go into TA/RA status.

Pilots are advised to maintain an increased visual awareness in this area. If operators believe that an aircraft should have triggered an alert, the incident should be reported to air traffic control as soon as possible.

This is due to a late notice Department of Defense exercise, and NBAA has voiced its concern to the FAA that these sort of significant impact tests need much more notice to operators in the NAS.

The NOTAM numbers are as follows:
•5/2817 New York Center (ZNY)
•5/2818 Washington Center (ZDC)
•5/2819 Jacksonville Center (ZJX)
•5/2820 Miami Center (ZMA)
•5/2834 NY Oceanic (ZWY)

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.”

The outages are scheduled to last until midnight October 1. In addition to the areas of concern noted in domestic airspace, the FAA said the outages might well extend up to 200-nm offshore.

The agency said one outage symptom could be the tracks of nearby aircraft first appearing close to the primary aircraft that immediately switch to a traffic alert/resolution alert status on TCAS. Pilots should maintain a heightened watch on the airspace around them and report any incidents of nearby aircraft they believe should have generated alerts, but did not. The relevant Notam numbers are 5/2817, 5/2818, 5/2819, 5/2820 and 5/2834.
