Narrative:

Approaching refil intersection on the scurry 1 arrival at the dallas ft worth international airport, TCASII gave us a TA while my copilot was flying. I looked at the TCASII display and noticed an intruder at 11 O'clock and -1400 below us. Within a few seconds TCASII gave us an RA and a climb, climb, climb, command. My first officer then started a climb out of 11000 ft assigned altitude. I called approach control and told them of our action. The controller then told us that our traffic was leveling at 10000 ft. Also, the vertical speed indicator gave us a climb command. After the controller talked to us, TCASII gave us a 'clear of conflict' and I told the controller that we were turning to 11000 ft. Our highest altitude in this maneuver was 11500 ft. While flying into dfw quite often, I know that departures are held at 10000 ft while arrs are at 11000 ft. Even though our intruder was -1400 below us but climbing rapidly to 10000 ft, TCASII issued an RA command and we followed it. Supplemental information from acn 186786: note -- the TCASII RA was right. Dfw procedures are poor. Departures climb rapidly to 10000 while arrs remain at 11000. With only 1000 ft of separation, a fast climbing aircraft that missed its level off, would breach that small separation in just a few seconds at least 2000 ft of separation should be provided in this high density area with fast climbing aircraft.

Title: ALT DEV ALT EXCURSION BY ACR MLG AFTER TCASII RA.

Narrative: APCHING REFIL INTXN ON THE SCURRY 1 ARR AT THE DALLAS FT WORTH INTL ARPT, TCASII GAVE US A TA WHILE MY COPLT WAS FLYING. I LOOKED AT THE TCASII DISPLAY AND NOTICED AN INTRUDER AT 11 O'CLOCK AND -1400 BELOW US. WITHIN A FEW SECONDS TCASII GAVE US AN RA AND A CLB, CLB, CLB, COMMAND. MY FO THEN STARTED A CLB OUT OF 11000 FT ASSIGNED ALT. I CALLED APCH CTL AND TOLD THEM OF OUR ACTION. THE CTLR THEN TOLD US THAT OUR TFC WAS LEVELING AT 10000 FT. ALSO, THE VERT SPD INDICATOR GAVE US A CLB COMMAND. AFTER THE CTLR TALKED TO US, TCASII GAVE US A 'CLR OF CONFLICT' AND I TOLD THE CTLR THAT WE WERE TURNING TO 11000 FT. OUR HIGHEST ALT IN THIS MANEUVER WAS 11500 FT. WHILE FLYING INTO DFW QUITE OFTEN, I KNOW THAT DEPS ARE HELD AT 10000 FT WHILE ARRS ARE AT 11000 FT. EVEN THOUGH OUR INTRUDER WAS -1400 BELOW US BUT CLBING RAPIDLY TO 10000 FT, TCASII ISSUED AN RA COMMAND AND WE FOLLOWED IT. SUPPLEMENTAL INFO FROM ACN 186786: NOTE -- THE TCASII RA WAS RIGHT. DFW PROCS ARE POOR. DEPS CLB RAPIDLY TO 10000 WHILE ARRS REMAIN AT 11000. WITH ONLY 1000 FT OF SEPARATION, A FAST CLBING ACFT THAT MISSED ITS LEVEL OFF, WOULD BREACH THAT SMALL SEPARATION IN JUST A FEW SECONDS AT LEAST 2000 FT OF SEPARATION SHOULD BE PROVIDED IN THIS HIGH DENSITY AREA WITH FAST CLBING ACFT.
