S Voigt NATCA safety,
Be fair on Huggie I think you will find that he didn't say we could see everything out there. He did say that out to twelve miles whatever is squaking he will see, Which is not too unreasonable thing to presume as the surveillance volume of the TCAS system scans range of approximately 40 nm and 9000 feet above and below the aircraft.
As far as the overloading issue, with which I agree by the way. TCAS 2 can track as many as 45 aircraft, display up to 30 of them and can coordinate a resolution advisory for up to 3 intruders at once. Which gives me a pretty good view of the situation that I am in.
