Narrative:

Descending to clearance altitude of 13000 ft and going direct to heleon intersection (128 degree radial of hnk VOR), we got a TCASII TA at 17000 ft and then a TCASII RA of 16700 ft. We then initiated a climb as shown by TCASII ZBW advised a light twin at 12 O'clock and 16500 ft. TCASII worked very well. We then continued descent for a landing at newark.

Title: POTENTIAL CONFLICT BTWN OPPOSITE DIRECTION TFC, 1 IFR, THE OTHER VFR.

Narrative: DSNDING TO CLRNC ALT OF 13000 FT AND GOING DIRECT TO HELEON INTXN (128 DEG RADIAL OF HNK VOR), WE GOT A TCASII TA AT 17000 FT AND THEN A TCASII RA OF 16700 FT. WE THEN INITIATED A CLB AS SHOWN BY TCASII ZBW ADVISED A LIGHT TWIN AT 12 O'CLOCK AND 16500 FT. TCASII WORKED VERY WELL. WE THEN CONTINUED DSCNT FOR A LNDG AT NEWARK.
