Mr Chimbu
I'm confused about
FTDK has purchased a handheld TCAD unit recently that provides TA (no RA) just from the signals received from proximate transponders
I felt such equipment only responded to such nearby trabsponders when within radar coverage and did not work outside radar coverage.
Could you please check and let us know. If it only works in radar cover areas, then ADS-B is a much more efficient mitigator as it would work on direct ADS-B OUT to ADS-B IN anywhere even away from ADS-B ground stations.
