Narrative:

Operating as air carrier X flight xx mia-fpo, cruising at 7000 ft on br 66V, an air carrier Y was fll-NAS level at 6000 ft converging from our 7 O'clock position. On another frequency the air carrier Y flight was told of our position and they apparently advised they could keep us in sight to climb to 8000 ft. This was unknown to us. As they climbed and approached us from our 7 O'clock position, TCASII changed to advisory with them at 1000 ft lower and climbing, converging towards us. Very quickly, TCASII advised RA and to climb immediately at least 4000 FPM to avoid traffic. I, as captain and on the best side to view the traffic from our left and slightly behind, saw the air carrier Y flight BE1900. The air carrier Y flight was very close and climbing. We responded to the RA and climbed to approximately 8500 ft prior to conflict resolution. ATC was advised and he stated that another controller had allowed the flight to climb with us in sight. To correct this from recurring, controller on one frequency should at least advise the next sector's controller of a converging flight path and that one aircraft is keeping visual but the other (mine) knows nothing of it.

Original NASA ASRS Text

Title: FLC OF AN MDT TURBOPROP CLBED IN RESPONSE TO A TCASII RA.

Narrative: OPERATING AS ACR X FLT XX MIA-FPO, CRUISING AT 7000 FT ON BR 66V, AN ACR Y WAS FLL-NAS LEVEL AT 6000 FT CONVERGING FROM OUR 7 O'CLOCK POS. ON ANOTHER FREQ THE ACR Y FLT WAS TOLD OF OUR POS AND THEY APPARENTLY ADVISED THEY COULD KEEP US IN SIGHT TO CLB TO 8000 FT. THIS WAS UNKNOWN TO US. AS THEY CLBED AND APCHED US FROM OUR 7 O'CLOCK POS, TCASII CHANGED TO ADVISORY WITH THEM AT 1000 FT LOWER AND CLBING, CONVERGING TOWARDS US. VERY QUICKLY, TCASII ADVISED RA AND TO CLB IMMEDIATELY AT LEAST 4000 FPM TO AVOID TFC. I, AS CAPT AND ON THE BEST SIDE TO VIEW THE TFC FROM OUR L AND SLIGHTLY BEHIND, SAW THE ACR Y FLT BE1900. THE ACR Y FLT WAS VERY CLOSE AND CLBING. WE RESPONDED TO THE RA AND CLBED TO APPROX 8500 FT PRIOR TO CONFLICT RESOLUTION. ATC WAS ADVISED AND HE STATED THAT ANOTHER CTLR HAD ALLOWED THE FLT TO CLB WITH US IN SIGHT. TO CORRECT THIS FROM RECURRING, CTLR ON ONE FREQ SHOULD AT LEAST ADVISE THE NEXT SECTOR'S CTLR OF A CONVERGING FLT PATH AND THAT ONE ACFT IS KEEPING VISUAL BUT THE OTHER (MINE) KNOWS NOTHING OF IT.
