Narrative:

We were on an IFR flight plan flying the brook 2 arrival into gso cleared to cross the 35 mi fix on the brook 2 at 11000 ft. At 13200 ft and approximately 42-45 mi out, another aircraft showed up on TCASII climbing toward me and I asked the controller what he wanted me to do. He said I 'might want to level off at 13000 ft.' so I did. The VFR gulfstream continued to climb straight at me. The gulfstream pilot verified with the controller that I was going to level off at 13000 ft. At about 1 1/2 mi separation and 200 ft vertical separation, I could see that the gulfstream intended to continue his climb through 13000 ft, so I added power and climbed. I was at 13600 ft when the gulfstream passed directly under me with 400 ft clearance. I was operating air carrier abcd flying cvg direct gso and this occurred at XA55 on feb/xa/00. The controller did not issue any avoidance vector or altitude change to me (negligence) and the VFR aircraft saw, but did not avoid me (no situational awareness). While I can't understand why things like this happen, they do. What was most disturbing to me was the controller's insistence that I make the 11000 ft crossing restr. If the 2 of us had collided (and it was close) he'd have a little more to worry about than some restr on a piece of paper.

Title: B737 AND GULFSTREAM HAD NMAC IN ZTL CLASS E AIRSPACE.

Narrative: WE WERE ON AN IFR FLT PLAN FLYING THE BROOK 2 ARR INTO GSO CLRED TO CROSS THE 35 MI FIX ON THE BROOK 2 AT 11000 FT. AT 13200 FT AND APPROX 42-45 MI OUT, ANOTHER ACFT SHOWED UP ON TCASII CLBING TOWARD ME AND I ASKED THE CTLR WHAT HE WANTED ME TO DO. HE SAID I 'MIGHT WANT TO LEVEL OFF AT 13000 FT.' SO I DID. THE VFR GULFSTREAM CONTINUED TO CLB STRAIGHT AT ME. THE GULFSTREAM PLT VERIFIED WITH THE CTLR THAT I WAS GOING TO LEVEL OFF AT 13000 FT. AT ABOUT 1 1/2 MI SEPARATION AND 200 FT VERT SEPARATION, I COULD SEE THAT THE GULFSTREAM INTENDED TO CONTINUE HIS CLB THROUGH 13000 FT, SO I ADDED PWR AND CLBED. I WAS AT 13600 FT WHEN THE GULFSTREAM PASSED DIRECTLY UNDER ME WITH 400 FT CLRNC. I WAS OPERATING ACR ABCD FLYING CVG DIRECT GSO AND THIS OCCURRED AT XA55 ON FEB/XA/00. THE CTLR DID NOT ISSUE ANY AVOIDANCE VECTOR OR ALT CHANGE TO ME (NEGLIGENCE) AND THE VFR ACFT SAW, BUT DID NOT AVOID ME (NO SITUATIONAL AWARENESS). WHILE I CAN'T UNDERSTAND WHY THINGS LIKE THIS HAPPEN, THEY DO. WHAT WAS MOST DISTURBING TO ME WAS THE CTLR'S INSISTENCE THAT I MAKE THE 11000 FT XING RESTR. IF THE 2 OF US HAD COLLIDED (AND IT WAS CLOSE) HE'D HAVE A LITTLE MORE TO WORRY ABOUT THAN SOME RESTR ON A PIECE OF PAPER.
