AN AERIAL DEMONSTRATION TEAM MADE A MIL STYLE OVERHEAD PATTERN WITHOUT COORDINATING WITH THE TWR. CONSEQUENTLY; THE RPTR IN THE FOLLOWING ACFT WAS TOLD TO GAR AND DIRECTED IN THE DIRECTION AND IN CONFLICT WITH THE DEMONSTRATION FLT OVERHEAD PATTERN.

Narrative

DURING A MODIFIED DOWNWIND ON APCH TO FLL WE HEARD APCH CTL TALK TO FLT A AND FLT F. THEY APPEARED TO BE SETTING UP FOR A STRAIGHT-IN TO RWY 9L AND WE COULDN'T DETERMINE IF THERE WERE 2 SINGLE ACFT OR A FLT OF SEVERAL ACFT. FLT A EVENTUALLY CALLED THE FIELD IN SIGHT AND WAS CLRED BY APCH FOR A VISUAL TO RWY 9L. OUR ACFT (ACR XYZ) WAS SUBSEQUENTLY TURNED ONTO FINAL VIA A 120 DEG HDG AT 2000 FT APPROX 7-8 MI OUTSIDE NOVAE (6.9 DME) AND CLRED THE ILS TO RWY 9L. APCHING NOVAE WE RECEIVED CLRNC AND CHANGED TO TWR AT FLL. TWR CLRED US TO LAND AND ADVISED US OF A FLT OF 6 ACFT IN FRONT OF US ON FINAL. WE HAD BOTH THE ARPT AND FLT IN SIGHT AS WE PROCEEDED DOWN FINAL. THE FLT APPEARED TO BE TURNING ONTO FINAL AS A 6- SHIP FORMATION FROM A L BASE. ONCE THEY WERE LINED UP ON FINAL THEY TURNED THEIR DEMONSTRATION SMOKE ON AND WE ASSUMED THEY WOULD BE MAKING A LOW PASS AND THEN COMING BACK AROUND TO SET UP FOR LNDG. SPACING AT THIS POINT BTWN OUR ACFT AND THE FLT LOOKED GOOD (4-5 MI). HOWEVER; INSTEAD OF PROCEEDING STRAIGHT AHEAD AS A FLT; THE 6-SHIP STARTED TO PITCH OUT TO THE N FOR LNDG. NOW THERE WERE 6 ACFT STRUNG OUT ON A DOWNWIND N OF THE ARPT GOING NOSE TO NOSE WITH OUR ACFT. AT THIS POINT TWR ABRUPTLY/EXCITEDLY GAVE US A TURN TO 360 DEGS AND TOLD US TO CLB TO 2000 FT. OUR CURRENT POS WAS APPROX 800-1000 FT AGL AND ABOUT 2 1/2 - 3 MI FROM THE RWY. WE INITIATED THE GAR AT THIS POINT STARTING A TURNING CLB. BECAUSE WE WERE MAKING A TURN INTO THE LNDG FLT OF 6 WE WERE CONCERNED ABOUT THEIR POS AS OUR TURN BLOCKED OUT THE 6 ACFT. AS A RESULT; WE OVERSHOT 2000 FT GOING TO 2400 FT BEFORE STOPPING OUR CLB. ONCE WE WERE STABILIZED ON THE 360 DEG HDG AND NO CONFLICT WAS IMMINENT; WE WERE STARTING BACK DOWN TO 2000 FT WHEN WERE SUBSEQUENTLY CLRED TO 3200 FT AND THEN 4000 FT. DURING THE GAR TWR HANDED US OFF TO APCH CTL AND THIS ADDED TO THE CONFUSION AS WE WERE TRYING TO AVOID THE 6 ACFT. ONCE BACK WITH APCH CTL WE WERE VECTORED FOR AN UNEVENTFUL APCH AND LNDG TO RWY 9L AT FLL. WX WAS NOT A FACTOR AT THE TIME; RPTED 2500 FT SCATTERED; 15 MI VISIBILITY; WINDS 110 DEGS 15 KTS. THE PROB IT APPEARED TO US WAS CONFUSION AS TO WHAT THE FLT WAS GOING TO DO. OBVIOUSLY TWR DID NOT EXPECT THE FLT TO PITCH OUT FOR LNDG OR THEY WOULD NOT HAVE LET US BE CLRED FOR APCH AND LNDG. I THOUGHT THE DEMONSTRATION FLTS HAD LIAISON OFFICERS PRECEDING A TEAM'S ARR TO COORDINATE ARR TIMES; AIRSPACE; AND OTHER SPECIAL REQUIREMENTS. A LIAISON OFFICER IN THE TWR WOULD HAVE PROBABLY ELIMINATED THE MASS CONFUSION WE EXPERIENCED.
