Narrative:
First officer flying air carrier X level at 9000 ft passing over clt. Airport told to fly heading 360 for radar vectors for runway 18R. Received notice from TCASII to make an immediate climb because of aircraft approaching from below. I made an immediate climb to 9300 then realized the aircraft below us leveled at 8000. The aircraft that approached from below was air carrier Y, medium large transport which has an excessive climb rate at low altitudes, this can cause occasionally close TCASII alert problems for other aircraft.
Original NASA ASRS Text
Title: ACR X TCASII RA EVASIVE ACTION TAKEN CLB FROM ASSIGNED ALT. NONADHERENCE TO ATC CLRNC.
Narrative: FO FLYING ACR X LEVEL AT 9000 FT PASSING OVER CLT. ARPT TOLD TO FLY HDG 360 FOR RADAR VECTORS FOR RWY 18R. RECEIVED NOTICE FROM TCASII TO MAKE AN IMMEDIATE CLB BECAUSE OF ACFT APCHING FROM BELOW. I MADE AN IMMEDIATE CLB TO 9300 THEN REALIZED THE ACFT BELOW US LEVELED AT 8000. THE ACFT THAT APCHED FROM BELOW WAS ACR Y, MLG WHICH HAS AN EXCESSIVE CLB RATE AT LOW ALTS, THIS CAN CAUSE OCCASIONALLY CLOSE TCASII ALERT PROBLEMS FOR OTHER ACFT.
