Narrative:
I departed agc assigned heading 260 degrees. I was handed over to pit approach who gave me turn to heading 290 degrees and slow to 180 KTS. At this point I was level at 3000 ft and accelerating towards 240 KTS. So I turned and pulled the throttles to idle and applied full speed brakes. This is very aggressive, but we were empty (zero passenger). The citation 10 is a very clean aircraft and we were at maximum landing weight. Approximately 20-30 seconds later approach called back and said 'I said speed 180 KTS, turn to heading 270 degrees and descend to 2500 ft.' then he cleared me for the visual. He then called and asked for what my original speed was. We said '250 KTS.' I believe if they had assigned me a speed off of agc it would have prevented this. I also may have caused some issue by being so fast, but I was unaware of any restr. I suspect it was poor planning on our part to be fast in the terminal area, but also poor planning on the controller's part to space a slow turboprop ahead of a high performance jet that was operating at its highest landing weight and reference speed. Supplemental information from acn 542675: repos flight from agc to pit approximately 15 NM away. Once clearing class D airspace and entering class B airspace, the captain accelerated towards 250 KTS for improved maneuvering capability due to our heavy weight at the time. Our proximity to another aircraft began to concern the controller. He canceled our clearance and revectored us for spacing. The citation X is a difficult aircraft to slow and does not happen quickly.

Title: TFC SEPARATION VECTORING OCCURS FOR A REPOSITIONING CE750 FROM AGC TO PIT WHEN THE ACFT WAS NOTED AT 250 KTS FOLLOWING A SLOWER TURBOPROP, #2 FOR APCH TO PIT, PA.
Narrative: I DEPARTED AGC ASSIGNED HDG 260 DEGS. I WAS HANDED OVER TO PIT APCH WHO GAVE ME TURN TO HDG 290 DEGS AND SLOW TO 180 KTS. AT THIS POINT I WAS LEVEL AT 3000 FT AND ACCELERATING TOWARDS 240 KTS. SO I TURNED AND PULLED THE THROTTLES TO IDLE AND APPLIED FULL SPD BRAKES. THIS IS VERY AGGRESSIVE, BUT WE WERE EMPTY (ZERO PAX). THE CITATION 10 IS A VERY CLEAN ACFT AND WE WERE AT MAX LNDG WT. APPROX 20-30 SECONDS LATER APCH CALLED BACK AND SAID 'I SAID SPD 180 KTS, TURN TO HDG 270 DEGS AND DSND TO 2500 FT.' THEN HE CLRED ME FOR THE VISUAL. HE THEN CALLED AND ASKED FOR WHAT MY ORIGINAL SPD WAS. WE SAID '250 KTS.' I BELIEVE IF THEY HAD ASSIGNED ME A SPD OFF OF AGC IT WOULD HAVE PREVENTED THIS. I ALSO MAY HAVE CAUSED SOME ISSUE BY BEING SO FAST, BUT I WAS UNAWARE OF ANY RESTR. I SUSPECT IT WAS POOR PLANNING ON OUR PART TO BE FAST IN THE TERMINAL AREA, BUT ALSO POOR PLANNING ON THE CTLR'S PART TO SPACE A SLOW TURBOPROP AHEAD OF A HIGH PERFORMANCE JET THAT WAS OPERATING AT ITS HIGHEST LNDG WT AND REF SPD. SUPPLEMENTAL INFO FROM ACN 542675: REPOS FLT FROM AGC TO PIT APPROX 15 NM AWAY. ONCE CLRING CLASS D AIRSPACE AND ENTERING CLASS B AIRSPACE, THE CAPT ACCELERATED TOWARDS 250 KTS FOR IMPROVED MANEUVERING CAPABILITY DUE TO OUR HVY WT AT THE TIME. OUR PROX TO ANOTHER ACFT BEGAN TO CONCERN THE CTLR. HE CANCELED OUR CLRNC AND REVECTORED US FOR SPACING. THE CITATION X IS A DIFFICULT ACFT TO SLOW AND DOES NOT HAPPEN QUICKLY.
