CAPT OF AN ACR LTT TURBOPROP TOOK EVASIVE ACTION BY MAKING S-TURNS ON FINAL APCH TO ALLOW MORE SPACING FOR A CARGO B727 TO TAKE OFF IN FRONT OF HIM. THE TWR CLRED THE B727 PRIOR TO IT REACHING THE RWY SO IT TOOK LONGER THAN THE TWR ESTIMATED FOR THE B727 TO ACTUALLY TAKE OFF AND CLR THE RWY.

Narrative

ON DEC/XA/98 AT APPROX XA50 WE WERE CLRED FOR ILS RWY 22 BY ROC APCH. WE WERE #2 WITH NO OTHER TFC BEHIND US. SPACING BTWN OUR ACFT AND B737 WAS APPROX 4 MI ON TCASII. WE WERE ASKED BY ROC APCH TO SLOW TO 170 KTS FOR TFC IN FRONT OF US. SINCE WE GAINED ANOTHER APPROX 1.5 MI ON ACR; ROC APCH ASKED US AGAIN TO SLOW FURTHER DOWN TO 150 KTS. SPACING WAS STILL TOO TIGHT. AT THIS TIME WE WERE IN VISUAL CONTACT WITH ACR TFC; AND THE ARPT AND RWY 22. SINCE THERE WAS NO OTHER TFC BEHIND US; I SLOWED FURTHER DOWN TO 140 KTS AND 130 KTS. THEN WE WERE HANDED OFF TO THE TWR. WE CALLED THE TWR AND SAID 'ROC TWR ON ILS 22' AND TWR REPLIED; '#2 FOR LNDG ONE DEP BEFORE YOU; CONTINUE.' WE NOTICED ACFT Y APPROX 500 FT FROM THE RWY 22 HOLD SHORT LINE ON TXWY C WAS CLRED FOR IMMEDIATE TKOF. WE ALSO NOTICED ACFT Y STARTED TO TAXI AT A VERY SLOW TAXI SPD. SINCE WE WERE VMC AND WE TRIED VERY HARD TO COMMUNICATE WITH THE TWR BUT HE WAS TOO BUSY TALKING TO ACFT Y IN EFFORT TO GET HIM TO MOVE OR TAXI FASTER DUE TO LNDG TFC 'US.' AT THIS TIME I HAD TO MAKE A DECISION TO EITHER GO AROUND; OR DO S-TURNS TO GAIN TIME AND LET THE TWR KNOW I WAS UNABLE TO REACH THE TWR. SINCE I THOUGHT MISSED APCH WILL PUT US IN TKOF PATH AND CREATE CONFLICT; I STARTED 1 S-TURN AND ACFT Y WAS OVER THE RWY NUMBERS AND ADDING PWR. I HAD APPROX 1.5 MI TO THE RWY. I TRIED TO EXPLAIN TO THE TWR AS TO WHY I TOOK THAT KIND OF ACTION. IN MY OPINION; THE TWR SHOULDN'T HAVE CLRED THE ACR Y FOR TKOF.
