"Ghost Targets" on TCAS!?
My event last Thursday: Maintaining 3000', 200 KIAS on a radar vector for a PAR Approach into Wittmund Airbase (ETNT), 10 NM South of the airfield on downwind leg.
Suddenly one Target popped up on TCAS display in my seven o' clock position, 1200' lower than me. TRAFFIC-TRAFFIC was announced. The one target thereafter split into two, then into four targets, CLIMB-CLIMB was issued. Reaching 4000' in the TCAS climb gave CLEAR OF CONFLICT and targets were gone. Never had visual contact to anybody.
Asking ATC what was going on, they said, they had no traffic that close, only two VFR targets, but far enough away.
Later on the ground I talked to a guy who regulary flies out of Wittmund. He said that they built a large wind-power-plant park south of the airfield and that this park already had distracted GCA and airborne radars.
I never heard of distracted TCAS-computers. Did anybody else hear anything similar to that?
Thanks for your inputs!!
