ADS-B, TCAS 'Unreliable' in U.S. Southeast

Friday, September 4, 2015 @ 8:00 AM

UPDATE: FAA Rescinds Southeast ADS-B Notam

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." 

ZNY NOTAM 5/2817 states that TCAS might fail to establish tracks on nearby aircraft and may not see aircraft that would normally trigger a TCAS resolution. False alerts, however, are not expected to be triggered during the exercise.  The FAA is advising pilots flying in the affected area to "maintain increased visual awareness" and to treat all traffic alerts as real.
