Key Takeaways:

The FAA has warned pilots of a month-long disruption to ADS-B and TCAS traffic avoidance systems in the Southeast (Virginia to Florida) throughout September due to military activities.
The National Business Aviation Association criticized the FAA for issuing the NOTAM (Notice to Airmen) with less than 24 hours' notice before the disruption began.
Pilots are advised that TCAS may fail to track or see nearby aircraft, and are urged to maintain increased visual awareness, treat all alerts as real, and report any missed collision advisories to ATC.

The FAA is warning pilots flying in the Southeast that ADS-B and TCAS traffic avoidance technology will be disrupted the entire month of September from Virginia to Florida because of “military activities.”

The National Business Aviation Association is complaining that such testing needs to be preceded by more warning. The FAA’s NOTAM on the signal disruption was posted less than 24 hours before the tests started on September 2.
