Narrative:
On takeoff clearance, flight crew, air carrier X, received takeoff clearance with a 080 degree vector. Takeoff clearance appeared normal considering the flight crew received an 'fll 8/preda transition' clearance on ACARS. On climb out, passing a 360 degree heading for 080 degrees, mia departure instructed flight crew to turn to a heading of 300 degrees. When queried by flight crew as to 'why the west vector,' mia departure claimed air carrier X should have been instructed to originally maintain a 290 degree heading out of fll. Flight crew explained to mia departure that the takeoff clearance included a 080 degree magnetic heading not 290 degrees. Mia departure was very professional and apologized for fll tower's apparent mistake. As a result of fll tower's incorrect clearance the flight crew encountered a minor conflict with a sabreliner jet that resulted in a 2 NM horizontal/1000-1200 ft vertical miss distance. Remainder of climb out was uneventful.
Original NASA ASRS Text
Title: B737 CREW OF FLL WAS ISSUED A 080 DEG HDG BY THE TWR THAT WAS CHANGED TO 300 DEGS BY THE DEP CTLR.
Narrative: ON TKOF CLRNC, FLC, ACR X, RECEIVED TKOF CLRNC WITH A 080 DEG VECTOR. TKOF CLRNC APPEARED NORMAL CONSIDERING THE FLC RECEIVED AN 'FLL 8/PREDA TRANSITION' CLRNC ON ACARS. ON CLBOUT, PASSING A 360 DEG HDG FOR 080 DEGS, MIA DEP INSTRUCTED FLC TO TURN TO A HEADING OF 300 DEGS. WHEN QUERIED BY FLC AS TO 'WHY THE W VECTOR,' MIA DEP CLAIMED ACR X SHOULD HAVE BEEN INSTRUCTED TO ORIGINALLY MAINTAIN A 290 DEG HDG OUT OF FLL. FLC EXPLAINED TO MIA DEP THAT THE TKOF CLRNC INCLUDED A 080 DEG MAGNETIC HEADING NOT 290 DEGS. MIA DEP WAS VERY PROFESSIONAL AND APOLOGIZED FOR FLL TWR'S APPARENT MISTAKE. AS A RESULT OF FLL TWR'S INCORRECT CLRNC THE FLC ENCOUNTERED A MINOR CONFLICT WITH A SABRELINER JET THAT RESULTED IN A 2 NM HORIZ/1000-1200 FT VERT MISS DISTANCE. REMAINDER OF CLBOUT WAS UNEVENTFUL.
