Narrative:
We were operating a B-767-200 as flight xyz, lhr-jfk. N90 cleared us to cross CCC VOR at 12000 ft, 250 KTS. As we leveled, TCASII gave us a yellow TA of opposite bound aircraft climbing through 11000 ft. When conflicting traffic passed 11500 ft, we received a red RA and a 'monitor vertical speed' visual and audio TCASII command. As PF, I disconnected the autoplt and automatic throttles and climbed to 12500 ft, watching conflicting VFR commuter aircraft pass 1 mi on right wing at 11700 ft. When clear, we descended back to assigned altitude of 12000 ft and advised N90 of evasive action. Recommendation: TRACON should advise IFR traffic of VFR conflicts, or near miss potential, when planned separation is less than 1000 ft.

Title: POTENTIAL CONFLICT WHEN COMMUTER ACR CLBS TOWARD OCCUPIED ALT OF INBOUND ACR B-767.
Narrative: WE WERE OPERATING A B-767-200 AS FLT XYZ, LHR-JFK. N90 CLRED US TO CROSS CCC VOR AT 12000 FT, 250 KTS. AS WE LEVELED, TCASII GAVE US A YELLOW TA OF OPPOSITE BOUND ACFT CLBING THROUGH 11000 FT. WHEN CONFLICTING TFC PASSED 11500 FT, WE RECEIVED A RED RA AND A 'MONITOR VERT SPD' VISUAL AND AUDIO TCASII COMMAND. AS PF, I DISCONNECTED THE AUTOPLT AND AUTO THROTTLES AND CLBED TO 12500 FT, WATCHING CONFLICTING VFR COMMUTER ACFT PASS 1 MI ON R WING AT 11700 FT. WHEN CLR, WE DSNDED BACK TO ASSIGNED ALT OF 12000 FT AND ADVISED N90 OF EVASIVE ACTION. RECOMMENDATION: TRACON SHOULD ADVISE IFR TFC OF VFR CONFLICTS, OR NEAR MISS POTENTIAL, WHEN PLANNED SEPARATION IS LESS THAN 1000 FT.
