Narrative:

During climb out, while level at 14000 ft, ZDC called out traffic at 11 O'clock position 16000 ft coming toward us. We reported seeing the traffic. Then we were cleared to climb to 17000 ft. The traffic was told to maintain heading and we were told to maintain visual separation. We did not have TCASII, but felt that the separation was not good and turned away from the traffic. At the same time the traffic was also making an evasive turn from us. The center controller asked the traffic if they got a TCASII alert and they said yes. Our flight continued on to destination, no comments from center.

Title: RPTR'S ACFT X WAS TOLD TO MAINTAIN VISUAL SEPARATION FROM ACFT Y. RPTR BECAME UNCOMFORTABLE AND TURNED AWAY FROM ACFT Y. AT THE SAME TIME ACFT Y BEGAN A TCASII EVASIVE MANEUVER TO CLR ACFT X.

Narrative: DURING CLBOUT, WHILE LEVEL AT 14000 FT, ZDC CALLED OUT TFC AT 11 O'CLOCK POS 16000 FT COMING TOWARD US. WE RPTED SEEING THE TFC. THEN WE WERE CLRED TO CLB TO 17000 FT. THE TFC WAS TOLD TO MAINTAIN HEADING AND WE WERE TOLD TO MAINTAIN VISUAL SEPARATION. WE DID NOT HAVE TCASII, BUT FELT THAT THE SEPARATION WAS NOT GOOD AND TURNED AWAY FROM THE TFC. AT THE SAME TIME THE TFC WAS ALSO MAKING AN EVASIVE TURN FROM US. THE CTR CTLR ASKED THE TFC IF THEY GOT A TCASII ALERT AND THEY SAID YES. OUR FLT CONTINUED ON TO DEST, NO COMMENTS FROM CTR.
