Narrative:

I was working the radar position at sector 16 (mayo) in the central area at ZJX en route center. The sector was split into a high and an ultra-high sector about 2-3 yrs ago. Sector 16 (mayo) owns from FL270 to but not including FL350; sector 86 (zepher) owns from FL350 to infinity. Aircraft #1 was en route to rsw airport in fort meyers; fl; at FL310 with a restr to cross pie (st petersburg VORTAC) at FL270 and 300 KTS or greater IAS. Aircraft #2; also en route to rsw; was being worked by sector 86 at FL370. The controller at R86 requested lower on aircraft #2 and I approved FL310. The 2 aircraft were 8 mi apart and on diverging courses. When aircraft #2 checked on frequency I turned him to a heading of 230 degrees for in-trail spacing behind aircraft #1. The turn was not sufficient and or timely enough to provide separation. The closest proximity was 4.63 mi and 600 ft; a minor technical violation. This situation occurs on a regular basis if the 2 sectors 16 and 86 do not display all arrs to a specific airport. In the past the sector 16 controller would have known about both aircraft with plenty of time to preplan turns for spacing and dscnts for traffic. However; on a regular day to day basis sector 86 will handoff an arrival aircraft to sector 16 with little time and/or room to comply with facility restrs and in-trail spacing.

Title: ZJX CTLR EXPERIENCED OPERROR AT FL310 WHEN ISSUING VECTORS FOR IN TRAIL SEQUENCING REQUIREMENTS.

Narrative: I WAS WORKING THE RADAR POS AT SECTOR 16 (MAYO) IN THE CENTRAL AREA AT ZJX ENRTE CTR. THE SECTOR WAS SPLIT INTO A HIGH AND AN ULTRA-HIGH SECTOR ABOUT 2-3 YRS AGO. SECTOR 16 (MAYO) OWNS FROM FL270 TO BUT NOT INCLUDING FL350; SECTOR 86 (ZEPHER) OWNS FROM FL350 TO INFINITY. ACFT #1 WAS ENRTE TO RSW ARPT IN FORT MEYERS; FL; AT FL310 WITH A RESTR TO CROSS PIE (ST PETERSBURG VORTAC) AT FL270 AND 300 KTS OR GREATER IAS. ACFT #2; ALSO ENRTE TO RSW; WAS BEING WORKED BY SECTOR 86 AT FL370. THE CTLR AT R86 REQUESTED LOWER ON ACFT #2 AND I APPROVED FL310. THE 2 ACFT WERE 8 MI APART AND ON DIVERGING COURSES. WHEN ACFT #2 CHKED ON FREQ I TURNED HIM TO A HDG OF 230 DEGS FOR IN-TRAIL SPACING BEHIND ACFT #1. THE TURN WAS NOT SUFFICIENT AND OR TIMELY ENOUGH TO PROVIDE SEPARATION. THE CLOSEST PROX WAS 4.63 MI AND 600 FT; A MINOR TECHNICAL VIOLATION. THIS SITUATION OCCURS ON A REGULAR BASIS IF THE 2 SECTORS 16 AND 86 DO NOT DISPLAY ALL ARRS TO A SPECIFIC ARPT. IN THE PAST THE SECTOR 16 CTLR WOULD HAVE KNOWN ABOUT BOTH ACFT WITH PLENTY OF TIME TO PREPLAN TURNS FOR SPACING AND DSCNTS FOR TFC. HOWEVER; ON A REGULAR DAY TO DAY BASIS SECTOR 86 WILL HDOF AN ARR ACFT TO SECTOR 16 WITH LITTLE TIME AND/OR ROOM TO COMPLY WITH FACILITY RESTRS AND IN-TRAIL SPACING.
