Narrative:

I called for local TA's from tower in that I heard 2 aircraft making practice approachs. The last sighted traffic was a twin engine jet on a practice NDB. I was descending for the initial segment, no lower than 2300 ft MSL. I had the traffic in sight and so I would pass off his left wing. My rate of descent was minimal and I actually passed off his left and above. He called the tower to say I was within 200 ft on his TCASII and he then reported a near miss. This would be a flagrant use of the system. Pilots should be aware of their surroundings at all times and not totally dependent on electronic devices. We were all on the same frequency and if he was at all attentive and alert, would have known exactly where I was and what I was doing. At no time was there any hazard (91.111). I was well clear (91.113). I was decelerating to proper speed (91.117).

Narrative: I CALLED FOR LCL TA'S FROM TWR IN THAT I HEARD 2 ACFT MAKING PRACTICE APCHS. THE LAST SIGHTED TFC WAS A TWIN ENG JET ON A PRACTICE NDB. I WAS DSNDING FOR THE INITIAL SEGMENT, NO LOWER THAN 2300 FT MSL. I HAD THE TFC IN SIGHT AND SO I WOULD PASS OFF HIS L WING. MY RATE OF DSCNT WAS MINIMAL AND I ACTUALLY PASSED OFF HIS L AND ABOVE. HE CALLED THE TWR TO SAY I WAS WITHIN 200 FT ON HIS TCASII AND HE THEN RPTED A NEAR MISS. THIS WOULD BE A FLAGRANT USE OF THE SYS. PLTS SHOULD BE AWARE OF THEIR SURROUNDINGS AT ALL TIMES AND NOT TOTALLY DEPENDENT ON ELECTRONIC DEVICES. WE WERE ALL ON THE SAME FREQ AND IF HE WAS AT ALL ATTENTIVE AND ALERT, WOULD HAVE KNOWN EXACTLY WHERE I WAS AND WHAT I WAS DOING. AT NO TIME WAS THERE ANY HAZARD (91.111). I WAS WELL CLR (91.113).
