ADS and TCAS 'Unreliable" For Entire Month of September Out to 200nm Off US East Coas
Anyone noticed this one:
A0369/15 (FDC 5/2817) - SPECIAL NOTICE...DUE TO MILITARY ACTIVITIES ON 1030/1090 MHZ, THE TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) AND AUTOMATIC DEPENDENT SYSTEM BROADCAST (ADS- SURVEILLANCE MAY BE UNRELIABLE IN THE AIRSPACE OVER THE STATES OF VIRGINIA, NORTH CAROLINA, SOUTH CAROLINA, GEORGIA, AND FLORIDA, AND EXTENDING APPROXIMATELY 200NM OFFSHORE. PILOTS ARE ADVISED THAT THE TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) MAY FAIL TO ESTABLISH TRACKS ON NEARBY AIRCRAFT AND MAY FAIL TO RECEIVE TRAFFIC ALERTS (TA) AND/OR RESOLUTION ADVISORIES (RA). FURTHER, PILOTS ARE ADVISED THAT TRACKS MAY FIRST APPEAR WITHIN CLOSE PROXIMITY TO THEIR AIRCRAFT AND MAY IMMEDIATELY GO INTO TA/RA STATUS. FALSE ALERTS ARE NOT EXPECTED TO BE GENERATED BY THIS MILITARY ACTIVITY AND ANY ALERTS SHALL BE TREATED AS REAL TCAS, ADS-B Unreliable on East Coast During September | Aerospace News: Aviation International News Seems pretty outrageous to me... Anyone with more specifics ? |
Sounds like Navy exercises in the VACAPES area off the SE Atlantic coast, that might include some radar jamming.
|
So a military exercise jeopardizing civilian air traffic safety. Nice :ugh:
|
TCAS and ADS-B, today, and in the affected region is NOT the primary means of aircraft separation. For instrument flight, the primary responsibility for separation rests on ATC and see-and-avoid. For visual flight, see-and-avoid is primary.
TCAS and ADS-B is secondary. Not an insignificant backup, but a backup nonetheless. |
This wouldn't be radar jamming.
Probably a new method of self separation or station keeping by the military. 1030/1090 ADSB hasn't ever been all that reliable in congested airspace anyways... :E |
