SCT CTLR HAS DIFFICULTY GETTING NEW CLRNC ACROSS TO FOREIGN PLT WHO IS INSTRUCTED TO MAKE A R 360 DEG TURN.

Narrative

THE ACFT WAS ENRTE TO LAX; DIRECT SLI AT 7000 FT IN HDOF STATUS TO THE LOS ANGELES ARR SECTOR. THE ARR SECTOR ADVISED MY HDOF PERSON THAT THE FLT NEEDED TO MAKE 1 '360 DEG' TURN; AND THEN THEY WOULD TAKE RADAR. I ADVISED ACFT X TO 'MAKE A R 360 DEG TURN BACK TO SLI FOR SPACING.' (THIS IS PHRASEOLOGY I HAD BEEN USING MY ENTIRE CAREER; THOUGHT WAS STANDARD; AND HAD NEVER HAD ANY PROB WITH BEFORE.) THE PLT ACKNOWLEDGED. WHEN AFTER A FEW MI I DID NOT OBSERVE A TURN; I ASKED THE PLT IF HE WAS BEGINNING HIS TURN. HE ANSWERED; IN A HVY ACCENT; IN THE AFFIRMATIVE. IN A COUPLE MORE MI; THE ACFT WAS RAPIDLY APCHING THE AIRSPACE BOUNDARY AND STILL HAD NOT TURNED. MY HDOF ADVISED THE ADJACENT SECTOR THAT WE WERE ATTEMPTING TO TURN THE ACFT; BUT WERE HAVING DIFFICULTIES. I THEN INSTRUCTED ACFT X TO 'TURN R HDG 140 DEGS.' THE PLT ACKNOWLEDGED; BUT STILL DID NOT TURN. SHORTLY; THE PLT ASKED 'VERIFY ACFT X WAS TO TURN L HDG 3-4-0.' I NOW VERY FIRMLY INSTRUCTED THE PLT 'NEGATIVE; TURN R IMMEDIATELY HDG 1-4-0.' THE ACFT FINALLY TURNED. (HE HAD CROSSED THE AIRSPACE BOUNDARY.) THE PLT NEVER KNEW WHAT I WANTED HIM TO DO. I REALIZE NOW THAT THE CORRECT PHRASEOLOGY IS 'TURN THREE HUNDRED AND SIXTY DEGS R.' DUE TO THE PLT'S LIMITED KNOWLEDGE OF ENGLISH; I'M NOT SURE EVEN THIS WOULD HAVE BEEN UNDERSTOOD. MY SPOUSE HAS SINCE ADVISED ME THAT THE ICAO PHRASEOLOGY IS 'MAKE A R ORBIT.' POSSIBLY THE PLT WOULD HAVE BEEN FAMILIAR WITH THIS PHRASE. I WILL TRY IT IN THE FUTURE WHEN NECESSARY. IN MY OPINION; UNITED STATES PHRASEOLOGY NEEDS TO BE STANDARDIZED TO THE REST OF THE WORLD. CONSIDERING THE NUMBER OF FOREIGN ACFT FLYING IN THE UNITED STATES. LUCKILY IN THIS CASE; THE ARR SECTOR WAS ABLE TO TAKE A POINTOUT AND NO OTHER TFC WAS A FACTOR.
