Narrative:

Aircraft Y departing runway 28 told to maintain 5000 ft, turn left on course 240 degrees. Aircraft X 10 mi southwest, northbound at 6000 ft. Act Y told of traffic. Called aircraft X in sight. Told aircraft Y to maintain visual separation with aircraft X and climb to 10000 ft. He acknowledged. Told aircraft X about aircraft Y and he called visual. Told to maintain visual separation and descended to 3000 ft. He acknowledged. Aircraft X advised of an RA and was descending back out of 7000 ft for 3000 ft. The problem: 1) reacting to an RA on an aircraft that he called in sight. 2) climbing with the aircraft above him. Prevention: carriers should have to turn TCASII off within 10000 ft and below 10000 ft. At the very least should not react to an RA with the aircraft 'in sight.'

Original NASA ASRS Text

Title: DC9 AND BE40 HAD A TCASII RA IN ROC CLASS C AIRSPACE.

Narrative: ACFT Y DEPARTING RWY 28 TOLD TO MAINTAIN 5000 FT, TURN L ON COURSE 240 DEGS. ACFT X 10 MI SW, NBOUND AT 6000 FT. ACT Y TOLD OF TFC. CALLED ACFT X IN SIGHT. TOLD ACFT Y TO MAINTAIN VISUAL SEPARATION WITH ACFT X AND CLB TO 10000 FT. HE ACKNOWLEDGED. TOLD ACFT X ABOUT ACFT Y AND HE CALLED VISUAL. TOLD TO MAINTAIN VISUAL SEPARATION AND DSNDED TO 3000 FT. HE ACKNOWLEDGED. ACFT X ADVISED OF AN RA AND WAS DSNDING BACK OUT OF 7000 FT FOR 3000 FT. THE PROB: 1) REACTING TO AN RA ON AN ACFT THAT HE CALLED IN SIGHT. 2) CLBING WITH THE ACFT ABOVE HIM. PREVENTION: CARRIERS SHOULD HAVE TO TURN TCASII OFF WITHIN 10000 FT AND BELOW 10000 FT. AT THE VERY LEAST SHOULD NOT REACT TO AN RA WITH THE ACFT 'IN SIGHT.'
