TCAS False alerts
Q. Does or can TCAS give false indications from wx radar stations?
Recently I have been flying with a portable TCAS or more correctly a PCAS, Zaon MRX to be specific. I have noted during AWK around Ceduna that the unit displays a target which appears at or near ground level, there is no level traffic.
My initial thought was that the unit is faulty as the MRX manual states that false indications are impossible.
However today I heard a REX 340 trying unsuccessfully to make contact with what they believed to be low level traffic near Ceduna. Couldn't get much comment from the crew as they were busy, but it appears their TCAS was showing same false TA.
Anyone experienced false indications, particularly from wx radar?
Regards
