I had noticed this before, and was waiting for an opportunity to ask about it.
I have 6 planes on the screen right now, all six show ADS-B under transponder. Four of them also show MLAT Yes. They are very close to each other.
- Does MLAT calculations apply to every plane seen, ADS-B or not?
- Why only 4 of the 6 were ‘MLATed’? They are too close to each other to not have been seen by other receivers.
