Narrative:

Mia tower issued takeoff clearance runway 12 and fly heading 120 degrees. Departure issued a clearance to turn and intercept the valley transition (mia 6 SID). I turned approximately 30 degrees left, the heading to effect a timely intercept on the departure radial. Departure then issued an immediate turn to 140 degrees and asked what heading tower had assigned. The first officer replied that tower had issued a 120 degree heading and that he (the departure controller) had told us to 'turn' and intercept the radial on the valley transition. Departure then issued a clearance to intercept the radial on our present heading. Listening to quanta xmissions to other flts departing behind us, it was apparent that the controller meant to say, 'intercept on present heading.' I feel that there was an error in the phraseology the controller used. It appears that he did not say exactly what he wanted us to do.

Original NASA ASRS Text

Title: S80 FLC DEPARTS FROM ASSIGNED HDG ON DEP FROM MIA.

Narrative: MIA TWR ISSUED TKOF CLRNC RWY 12 AND FLY HDG 120 DEGS. DEP ISSUED A CLRNC TO TURN AND INTERCEPT THE VALLEY TRANSITION (MIA 6 SID). I TURNED APPROX 30 DEGS L, THE HDG TO EFFECT A TIMELY INTERCEPT ON THE DEP RADIAL. DEP THEN ISSUED AN IMMEDIATE TURN TO 140 DEGS AND ASKED WHAT HDG TWR HAD ASSIGNED. THE FO REPLIED THAT TWR HAD ISSUED A 120 DEG HDG AND THAT HE (THE DEP CTLR) HAD TOLD US TO 'TURN' AND INTERCEPT THE RADIAL ON THE VALLEY TRANSITION. DEP THEN ISSUED A CLRNC TO INTERCEPT THE RADIAL ON OUR PRESENT HDG. LISTENING TO QUANTA XMISSIONS TO OTHER FLTS DEPARTING BEHIND US, IT WAS APPARENT THAT THE CTLR MEANT TO SAY, 'INTERCEPT ON PRESENT HDG.' I FEEL THAT THERE WAS AN ERROR IN THE PHRASEOLOGY THE CTLR USED. IT APPEARS THAT HE DID NOT SAY EXACTLY WHAT HE WANTED US TO DO.
