Narrative:

While cruising at 11000 ft at 250 KIAS on scurry 6 arrival at dfw, we received an RA from TCASII. RA occurred 15 seconds after approach controller called traffic as 11 O'clock, 2 mi, climbing to 10000 ft, md-80. We had a visual on traffic and saw him level at 10000 ft, so I elected to ignore climb command from TCASII. It is my impression that these 'false' TCASII warnings are quite frequent at dfw. All arrs are at 11000 ft, and all are converging. Why don't departing air carrier aircraft routinely reduce climb to 1000 FPM for the last 1000 ft on these types of approachs. I do this routinely at dfw (and ord), and I have never received a climbing RA. Unnecessary RA's are, in my opinion, a real danger at these types of terminals.

Title: AN ACR MLG PLT IGNORED HIS TCASII.

Narrative: WHILE CRUISING AT 11000 FT AT 250 KIAS ON SCURRY 6 ARR AT DFW, WE RECEIVED AN RA FROM TCASII. RA OCCURRED 15 SECONDS AFTER APCH CTLR CALLED TFC AS 11 O'CLOCK, 2 MI, CLBING TO 10000 FT, MD-80. WE HAD A VISUAL ON TFC AND SAW HIM LEVEL AT 10000 FT, SO I ELECTED TO IGNORE CLB COMMAND FROM TCASII. IT IS MY IMPRESSION THAT THESE 'FALSE' TCASII WARNINGS ARE QUITE FREQUENT AT DFW. ALL ARRS ARE AT 11000 FT, AND ALL ARE CONVERGING. WHY DON'T DEPARTING ACR ACFT ROUTINELY REDUCE CLB TO 1000 FPM FOR THE LAST 1000 FT ON THESE TYPES OF APCHS. I DO THIS ROUTINELY AT DFW (AND ORD), AND I HAVE NEVER RECEIVED A CLBING RA. UNNECESSARY RA'S ARE, IN MY OPINION, A REAL DANGER AT THESE TYPES OF TERMINALS.
