Narrative:

ZBW asked us if we had traffic (Y) in sight at 2 O'clock position, 5 mi, 16000 ft. We replied 'affirmative' and were told to maintain visual and climb to FL230. During the climb we received an RA which we ignored because we had traffic Y in sight. Our RA directed us to descend, but we expedited our climb. Our traffic Y knew we had him in sight and he ignored his RA to climb -- he remained level. It was, nevertheless, unnerving to be executing a procedure contrary to an RA and hoping the other aircraft Y would do the same. We had traffic in sight at all times, but if he had complied with his RA it may have been a very bad situation.

Title: ACR FLC IGNORES TCASII RA, UTILIZES VISUAL SEPARATION WITH ANOTHER ACR ACFT.

Narrative: ZBW ASKED US IF WE HAD TFC (Y) IN SIGHT AT 2 O'CLOCK POS, 5 MI, 16000 FT. WE REPLIED 'AFFIRMATIVE' AND WERE TOLD TO MAINTAIN VISUAL AND CLB TO FL230. DURING THE CLB WE RECEIVED AN RA WHICH WE IGNORED BECAUSE WE HAD TFC Y IN SIGHT. OUR RA DIRECTED US TO DSND, BUT WE EXPEDITED OUR CLB. OUR TFC Y KNEW WE HAD HIM IN SIGHT AND HE IGNORED HIS RA TO CLB -- HE REMAINED LEVEL. IT WAS, NEVERTHELESS, UNNERVING TO BE EXECUTING A PROC CONTRARY TO AN RA AND HOPING THE OTHER ACFT Y WOULD DO THE SAME. WE HAD TFC IN SIGHT AT ALL TIMES, BUT IF HE HAD COMPLIED WITH HIS RA IT MAY HAVE BEEN A VERY BAD SIT.
