Narrative:
In this situation the RA commanded a pullup, which would have put us on a collision track with the air carrier. I ignored the pullup, since I could see the aircraft. But, what if we had been on instruments?! Something was left to be desired here. We were given 10 mi to descend to FL190 (made it in 9 mi) through the air carrier mg altitude, and to level at the same altitude as the opp direction twin.

Title: TCASII RA IGNORED AS PIC HAS TRAFFIC IN SIGHT AFTER TRAFFIC ADVISORY GIVEN. RADAR VECTORING USED TO RESOLVE IN OPPOSITE DIRECTION TRAFFIC POTENTIAL CONFLICT.
Narrative: IN THIS SITUATION THE RA COMMANDED A PULLUP, WHICH WOULD HAVE PUT US ON A COLLISION TRACK WITH THE ACR. I IGNORED THE PULLUP, SINCE I COULD SEE THE ACFT. BUT, WHAT IF WE HAD BEEN ON INSTS?! SOMETHING WAS LEFT TO BE DESIRED HERE. WE WERE GIVEN 10 MI TO DSND TO FL190 (MADE IT IN 9 MI) THROUGH THE ACR MG ALT, AND TO LEVEL AT THE SAME ALT AS THE OPP DIRECTION TWIN.
