C310 LNDG ENCOUNTERED WAKE TURB BEHIND LNDG B757 AND DEPARTING MD-80.

Narrative

FLT FROM SANTA CATALINA VFR DUSK INTO SAN. AT MT SOLIDAD CLRED TO FOLLOW B757 ON VISUAL RWY 27. I FLY INTO SAN FREQUENTLY; AND I OFFER TO KEEP 170 KTS UNTIL ABOUT 3 NM (MY GEAR SPD IS 140) TO FIT INTO APCH FLOW. I ALSO KNOW ABOUT THE WAKE CHARACTERISTICS OF THE B757; SO I AM CAREFUL TO STAY ABOVE ITS GLIDEPATH AND ASK FOR A LONG LNDG; WHICH IS APPROVED BY TWR. ALL SMOOTH UNTIL SHORT FINAL (GEAR AND FLAPS SET TO SCHEDULE) WHEN TWR CLRS AN MD80 FOR IMMEDIATE TKOF. I CAN'T BELIEVE IT! WHAT NOW? IF I STAY HIGH; I EAT THE WAKE OF THE DEPARTING MD-80; IF I WANT TO GO BELOW IT; I NEED TO GO THROUGH THE B757 WAKE - - OR I GAR; MESS UP THE PATTERN; INFURIATE THE CTLR; AND PAY FOR IT NEXT TIME I COME INTO SAN. FINE CHOICE. I DECIDE TO STAY SLIGHTLY HIGH AND UPWIND OF APCH PATH. STILL THE WAKE IS QUITE HVY (SQUEAKING PAX AND SUCH) AND I HAVE TO TOUCH DOWN LONG TO MAKE A SAFE LNDG. I AM TOO FED UP TO CALL TWR AND NOTIFY THEM OF THE BAD SIT THEY HELPED TO CREATE. I FEEL THAT A SIT LIKE THIS CAN BE AVOIDED. FIRST; ATC SHOULD NOT SQUEEZE ANOTHER LARGE ACFT IN FOR TKOF IF A SMALL AIRPLANE IS FOLLOWING A HVY. THE 3 MI SEPARATION BEHIND THE HVY MAKES SENSE; AND SQUEEZING A DEPARTING LARGE ACFT IN MAY BE FINE AND LEGAL AS FAR AS THE ATC'S HANDBOOK IS CONCERNED; BUT IT SURE IS RUDE AND NOT VERY THOUGHTFUL. SECOND; I THINK ONE SHOULD INDEED REJECT THE LNDG IN SUCH A SIT; GAR AND EXPLAIN TO ATC WHY. THEY MAY BE FED UP; BUT I FOUND THAT A CLARIFYING CALL TO THE TWR MGR USUALLY HELPS. I STILL FEEL THAT THERE IS A LOOPHOLE IN THE WAKE SEPARATION STANDARDS PERMITTING SUCH A PRACTICE. THE TRAILING PLT HAS TO MAKE A PLAN TO AVOID A HVY'S WAKE; AND I WANT TO BE SURE THAT I CAN RELY ON MY 3 NM SEPARATION. I UNDERSTAND THAT THERE IS NO SUCH REQUIREMENT BEHIND A LARGE ACFT AND IT APPEARS PERFECTLY LEGAL TO PLACE A LARGE ACFT'S WAKE IN BTWN THESE 3 NM; BUT IT SURE DOES FOLLOW ONLY THE LETTER OF THE LAW; AND NOT THE SPIRIT. ALSO; IF I TRY TO COOPERATE WITH ATC BY KEEPING SPDS UP TO FIT INTO A TRANSPORT JET PATTERN; THEN I DO NOT WANT STUNTS LIKE THAT PULLED ON ME. I GUESS THEY JUST DO NOT REALIZE WHAT PROBS CAN BE CREATED FOR SMALL AIRPLANES BY SUCH A PROC. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING: RPTR STATES HE WAS EXTREMELY SHAKEN BY THE EVENT. HE WILL NEVER CONTINUE TO LNDG IN SUCH A SIT AGAIN. HE WILL MAKE A GAR AND TAKE THE CONSEQUENCES. HE FEELS STRONGLY ABOUT THE MAINTAINING OF ESTABLISHED SEPARATION OF A GA ACFT BEHIND AN ACR. ALLOWING THE MD-80 DEP PUT HIM IN A TOTAL DILEMMA REGARDING HIS AVOIDANCE OF WAKE TURB: LAND LONG; LAND SHORT; STAY HIGH; STAY LOW. NOT VERY GOOD OPTIONS HERE. RPTR SEEMS VERY CONCERNED ABOUT FUTURE CONSEQUENCES IF HE COMPLAINS TOO MUCH. PERHAPS DUE TO A VERY RECOGNIZABLE ACCENT.
