ACR CAPT REPORTS BEING ISSUED CLIMB CLEARANCE BY ZMA WHILE STILL IN MDSD AIRSPACE. FLT CREW IS SUBJECTED TO VERBAL TIRADE AFTER ASKING FOR CONFIRMATION THAT MDSD IS AWARE OF THE CLEARANCE.

Narrative

ZMA CLRED OUR ACFT TO CLB TO FL300. READ BACK CLRNC AND QUERIED IF MDSD CTL APPROVED CLB AS WE WERE STILL IN MDSD AIRSPACE. CTLR REPEATED SAME CLRNC WITHOUT ACKNOWLEDGING QUERY. REPEATED SAME ACKNOWLEDGEMENT WITH SAME INQUIRY. CTLR REPEATS CLB TO FL300 WITH A SNIDE; CYNICAL REPEAT WITHOUT ANSWERING THE QUESTION IF WE WERE PERMITTED BY MDSD TO CLB WITHIN THEIR AIRSPACE. I STATED WE COULD USE A LITTLE LESS ATTITUDE AND CLARIFICATION PLEASE BEFORE CLBING TO FL300. ANOTHER VOICE JUMPS ON THE FREQ (SUPVR?); AND A VERY ANGRY TIRADE ENSUES. THE CTLR UNLOADS A VITRIOL UNLIKE ANY LACK OF COMPORTMENT THAT I'VE HEARD IN MY 34 YRS OF PROFESSIONAL AVIATION. THE CTLR IN HIS TIRADE STATES; 'ACR X; IF ZMA ISSUES YOU A CLRNC; WE EXPECT YOU TO COMPLY! WE KNOW WHAT WE'RE DOING DOWN HERE!' I REITERATED ONCE AGAIN; 'SIR; WE ARE FULLY CAPABLE OF COMPLYING WITH THE CLRNC TO CLB; THE ISSUE NEEDS TO BE RESOLVED IF MDSD APPROVES OUR CLB IN THEIR AIRSPACE.' OTHER ACFT ON FREQ BEGAN CALLING IN THEIR VALIDATION OF THIS SIMPLE REQUEST AND REQUIREMENT SINCE WE WERE S OF THE MIA FIR BOUNDARY. OUR ACFT WAS NOW AT BESAS; THE FIR BOUNDARY; MDSD NOW CLRED US TO CONTACT MIA; NEVER ONCE HAVING CLRED US OUT OF FL240. I NOW STATED ON THE RADIO AS A RESULT OF THE TENSION PRESENT; 'OK EVERYONE; TAKE A DEEP BREATH; ACR X IS DEPARTING FL240 FOR FL300.' NORMALLY WHEN ZMA CLEARS AN ACFT TO CLB WITH MDSD'S AIRSPACE; THE FACT IS STATED 'IF IT'S OK WITH SANTO DOMINGO YOU MAY NOW CLB TO SUCH AND SUCH;' OR; 'I JUST CLRED WITH SANTO DOMINGO ON A LANDLINE; YOU ARE NOW CLRED....' THIS WAS NEVER SPOKEN. CLB WAS COMPLETED WITHOUT INCIDENT. ACFT WAS NEVER IN A SITUATION WHERE A DEV CLRNC WAS NECESSARY. THE ONLY SAFETY COMPROMISE WAS THE VERY DYSFUNCTIONAL ATTITUDE AND LACK OF COMPORTMENT ADMINISTERED ON THIS RADIO FREQ BY ZMA AND THEIR INABILITY TO COMMUNICATE A CONCISE CLRNC WITH THE EDIFICATION IF COORD HAD BEEN CONDUCTED WITH MDSD CTL. THE SUPVR'S INTERVENTION WOULD NOT HAVE BEEN NEEDED IF THE FIRST CLB CLRNC OR QUERY WAS RESPONDED TO FACTUALLY TO THE QUESTION AT HAND. HE VITIATED A SCOLDING TIRADE THE LIKES OF WHICH WERE AN EMBARRASSMENT TO ALL WHO WERE LISTENING AND THUS THE INPUT FROM THE OTHER ACFT WHO WERE ON LISTENING WATCH.
