Narrative:

Departed using noise abatement procedure. At 800 ft MSL and 25 degrees nose up, climbing about 6000 FPM, we got a TCASII RA indicating traffic 100 ft above us. The ivsi commanded an approximately 4000 FPM descent. We notified ATC and lowered the nose from 25 degrees to 15 degrees and reduced power to idle. At 500 ft MSL we still had the RA, but I was concerned about getting a GPWS pull up command, so I leveled the aircraft. The RA became a TA and finally a non threat target. We never received an audio clear of conflict report. We notified ATC that we were clear and resumed climb. No further incident. I explained to the very shaken passenger and crew what had happened and told them all was well. Everyone seemed fine. We continued to dfw. I imagine we set off every noise monitor around.

Title: A B757 ON NOISE ABATEMENT DEP FLIES RESOLUTION DEMANDED BY TCASII AT 800 FT.

Narrative: DEPARTED USING NOISE ABATEMENT PROC. AT 800 FT MSL AND 25 DEGS NOSE UP, CLBING ABOUT 6000 FPM, WE GOT A TCASII RA INDICATING TFC 100 FT ABOVE US. THE IVSI COMMANDED AN APPROX 4000 FPM DSCNT. WE NOTIFIED ATC AND LOWERED THE NOSE FROM 25 DEGS TO 15 DEGS AND REDUCED PWR TO IDLE. AT 500 FT MSL WE STILL HAD THE RA, BUT I WAS CONCERNED ABOUT GETTING A GPWS PULL UP COMMAND, SO I LEVELED THE ACFT. THE RA BECAME A TA AND FINALLY A NON THREAT TARGET. WE NEVER RECEIVED AN AUDIO CLR OF CONFLICT RPT. WE NOTIFIED ATC THAT WE WERE CLR AND RESUMED CLB. NO FURTHER INCIDENT. I EXPLAINED TO THE VERY SHAKEN PAX AND CREW WHAT HAD HAPPENED AND TOLD THEM ALL WAS WELL. EVERYONE SEEMED FINE. WE CONTINUED TO DFW. I IMAGINE WE SET OFF EVERY NOISE MONITOR AROUND.
