Narrative:

Air carrier X on scurry arrival to dfw about 10-15 mi from dfw at 11000 ft, got a TCASII 'RA' with a very short 'TA' warning. The TCASII red arc commanded a 2000 + ft rate of climb, in the confusion caused by the loud 'climb, climb' aural, I tried to talk to ATC to check their traffic and to inform them that we were climbing, the first officer had climbed 500 ft, before I was able to stop him to indicate that the traffic Y was really no threat. Traffic Y showed (-1700) at 10 O'clock and was leveling at 10000 ft. (The dallas bump up problem) somehow pilots need to cut their rates of climb for the last 1000 ft to maximum 1000-1500 ft min. The glass cockpit jets need to have their computer reprogrammed to cut the climb rate for the last 1000 ft. These pilots inform me that it is hard for them to do this. Who is flying who - there is a problem when a pilot can not or are not trained to over ride or correct the autoplt computer. All my 'ras' have been caused by these high rates of closure by these glass cockpit jets. We need a method to silence the aural warning from TA's and RA's after the initial alert. In the busy approach phase this aural 'noise' is in itself a safety factor. I had trouble talking to and understanding ATC.

Title: ACR X TCASII RA FROM Y. EVASIVE ACTION TAKEN.

Narrative: ACR X ON SCURRY ARR TO DFW ABOUT 10-15 MI FROM DFW AT 11000 FT, GOT A TCASII 'RA' WITH A VERY SHORT 'TA' WARNING. THE TCASII RED ARC COMMANDED A 2000 + FT RATE OF CLB, IN THE CONFUSION CAUSED BY THE LOUD 'CLB, CLB' AURAL, I TRIED TO TALK TO ATC TO CHK THEIR TFC AND TO INFORM THEM THAT WE WERE CLBING, THE FO HAD CLBED 500 FT, BEFORE I WAS ABLE TO STOP HIM TO INDICATE THAT THE TFC Y WAS REALLY NO THREAT. TFC Y SHOWED (-1700) AT 10 O'CLOCK AND WAS LEVELING AT 10000 FT. (THE DALLAS BUMP UP PROB) SOMEHOW PLTS NEED TO CUT THEIR RATES OF CLB FOR THE LAST 1000 FT TO MAX 1000-1500 FT MIN. THE GLASS COCKPIT JETS NEED TO HAVE THEIR COMPUTER REPROGRAMMED TO CUT THE CLB RATE FOR THE LAST 1000 FT. THESE PLTS INFORM ME THAT IT IS HARD FOR THEM TO DO THIS. WHO IS FLYING WHO - THERE IS A PROB WHEN A PLT CAN NOT OR ARE NOT TRAINED TO OVER RIDE OR CORRECT THE AUTOPLT COMPUTER. ALL MY 'RAS' HAVE BEEN CAUSED BY THESE HIGH RATES OF CLOSURE BY THESE GLASS COCKPIT JETS. WE NEED A METHOD TO SILENCE THE AURAL WARNING FROM TA'S AND RA'S AFTER THE INITIAL ALERT. IN THE BUSY APCH PHASE THIS AURAL 'NOISE' IS IN ITSELF A SAFETY FACTOR. I HAD TROUBLE TALKING TO AND UNDERSTANDING ATC.
