Narrative:
On the date and time stated above, we received 2 TCASII RA advisories, corresponding to departures from dfw. The departures are cleared to 10000 ft, arrival route altitude 11000. The TCASII reacted to the closure rate of the departure aircraft and our inbound flight. RA was ignored as traffic was in sight. The real problem is that the TCASII alert caused such a distraction in the cockpit that 2 or more radio calls were missed from approach control. Had we been IMC we would have climbed, as it turned out we had a late descent clearance, and a high approach. TCASII is here to stay. It would be a great help if the arrs are at 12000 at dfw, while to departures stay at 10000, 2000 separation. The present 1000 separation has great potential for problems.

Title: RPTR COMPLAINS OF APCH PROC STAR.
Narrative: ON THE DATE AND TIME STATED ABOVE, WE RECEIVED 2 TCASII RA ADVISORIES, CORRESPONDING TO DEPS FROM DFW. THE DEPS ARE CLRED TO 10000 FT, ARR RTE ALT 11000. THE TCASII REACTED TO THE CLOSURE RATE OF THE DEP ACFT AND OUR INBOUND FLT. RA WAS IGNORED AS TFC WAS IN SIGHT. THE REAL PROBLEM IS THAT THE TCASII ALERT CAUSED SUCH A DISTR IN THE COCKPIT THAT 2 OR MORE RADIO CALLS WERE MISSED FROM APCH CTL. HAD WE BEEN IMC WE WOULD HAVE CLBED, AS IT TURNED OUT WE HAD A LATE DSCNT CLRNC, AND A HIGH APCH. TCASII IS HERE TO STAY. IT WOULD BE A GREAT HELP IF THE ARRS ARE AT 12000 AT DFW, WHILE TO DEPS STAY AT 10000, 2000 SEPARATION. THE PRESENT 1000 SEPARATION HAS GREAT POTENTIAL FOR PROBLEMS.
