Procedure; Company Policy; Aircraft; Airspace Structure
We were cleared the visual to 18R CLT. I had B737 traffic in sight approaching 18C from the east. I pointed out traffic to the flying First Officer and he shallowed his intercept angle. We were approximately 13 miles out at 4;000 FT when we got the TA followed by an RA to climb. The First Officer responded correctly but within seconds we got a command to descend even though the VSI was showing a 2;000 FPM climb command. I pointed this out and the First Officer continued to climb despite the ambiguous commands. I advised approach 'TCAS' climb. After clear of conflict we continued and landed without incident. Both aircraft on approach appeared to be exactly where they were supposed to be. This is not the first RA I have had at CLT with parallel approaches.
CRJ-700 Captain experiences a TCAS RA during visual approach to Runway 18R at CLT; caused by B737 traffic approaching Runway 18C. The RA command is initially to climb with the VSI indicating green in the climb direction then the command switches to descent with the VSI unchanged. The climb is continued until clear of conflict.
