Narrative:

Departed mia for tgu. We were cleared to FL330 from mia center and then handed off to havana center. We requested FL410. They gave us a heading of 210 degrees, climb to FL410. As we started the climb we noted an aircraft on TCASII 1500 ft above on the nose. At this point TCASII demanded a climb. Missed other aircraft by 1 mi horizontal/1000 vertical. TCASII worked great.

Title: TCASII RA SAVES THE DAY FOR CLBING DSNDING OPPOSITE DIRECTION TFC AFTER AMENDED CLRNC ALT ASSIGNMENT CHANGE IS GIVEN BY ARTCC RADAR CTLR.

Narrative: DEPARTED MIA FOR TGU. WE WERE CLRED TO FL330 FROM MIA CTR AND THEN HANDED OFF TO HAVANA CTR. WE REQUESTED FL410. THEY GAVE US A HDG OF 210 DEGS, CLB TO FL410. AS WE STARTED THE CLB WE NOTED AN ACFT ON TCASII 1500 FT ABOVE ON THE NOSE. AT THIS POINT TCASII DEMANDED A CLB. MISSED OTHER ACFT BY 1 MI HORIZ/1000 VERT. TCASII WORKED GREAT.
