A cpr LR60 on final at 2400 ft received a TCASII RA and told the tower he was making a left 360 degree turn due to the RA. The controller did not have any traffic in the area near the LR60 and feels that the TCASII should be turned to standby when in the traffic pattern.

Narrative:

I was working local control when an LR60 on 4 mi final advised that he had a TCASII RA and was executing a left 360 degree turn. There were no other aircraft in his immediate vicinity other than multiple aircraft doing touch-and-goes on a parallel runway (separated by 2800 ft). The TCASII aircraft is a local aircraft familiar with the amount of training being conducted at this airport. It is my opinion that company policy for this aircraft would be to put the TCASII in the 'stand by' mode in the terminal environment.

Title: A CPR LR60 ON FINAL AT 2400 FT RECEIVED A TCASII RA AND TOLD THE TWR HE WAS MAKING A L 360 DEG TURN DUE TO THE RA. THE CTLR DID NOT HAVE ANY TFC IN THE AREA NEAR THE LR60 AND FEELS THAT THE TCASII SHOULD BE TURNED TO STANDBY WHEN IN THE TFC PATTERN.

Narrative: I WAS WORKING LCL CTL WHEN AN LR60 ON 4 MI FINAL ADVISED THAT HE HAD A TCASII RA AND WAS EXECUTING A L 360 DEG TURN. THERE WERE NO OTHER ACFT IN HIS IMMEDIATE VICINITY OTHER THAN MULTIPLE ACFT DOING TOUCH-AND-GOES ON A PARALLEL RWY (SEPARATED BY 2800 FT). THE TCASII ACFT IS A LCL ACFT FAMILIAR WITH THE AMOUNT OF TRAINING BEING CONDUCTED AT THIS ARPT. IT IS MY OPINION THAT COMPANY POLICY FOR THIS ACFT WOULD BE TO PUT THE TCASII IN THE 'STAND BY' MODE IN THE TERMINAL ENVIRONMENT.
