TCASII WARNED THE RPTING ACFT OF ANOTHER ACFT IN AN EMER DSCNT.

Narrative

WHILE IN CRUISE AT FL330 ENRTE JFK-FRA; EXPERIENCED NEAR MISS WHILE IN CANADIAN AIRSPACE AT APPROX 49 DEGS N LAT AND 58 DEGS W LONGITUDE. I WAS THE PIC ADMINISTERING IOE TO A NEW CAPT. WORKING GANDER (NFLD) CTR; TOLD TO GO TO GANDER RADIO FOR OCEANIC CLRNC. (PROC REQUIRES ONE PLT TO MONITOR ATC WHILE OTHER PLT GETS CLRNC.) TRACK CLRNC RECEIVED VIA ACARS; BUT READBACK REQUIRED. AS CLRNC (WHICH WAS NOT THE FILED CLRNC OR ALT) WAS COMING OFF PRINTER; FLT ATTENDANT ENTERED COCKPIT FOR MEAL ORDERS. I READ BACK CLRNC; RETURNED TO CTR AS THEY (CTR) WERE GIVING US A L TURN TO 040 DEG (FROM ABOUT 070 DEGS). THEY THEN GAVE US R TO 120 DEG AND REPEATED IT 3 TIMES; APPARENTLY NOT HEARING MY READBACK. WE THEN HEARD 'TFC;TFC;' FOLLOWED BY 'CLB; CLB.' THE TCASII CLB INDICATORS IN THIS AIRPLANE ARE OUT OF THE PLT'S FIELD OF VIEW (A MONEY SAVING FEATURE); BUT THE RELIEF PLT; WHO WAS IN THE JUMP SEAT; TALKED THE PF THROUGH THE TCASII CLB MANEUVER. I OBSERVED THE TFC ENTER THE CTR MOUNTED DISPLAY FROM THE TOP; TURN RED; AND PASS OFF OUR L WING ABOUT 3 MI AT FL332 DSNDING. CTR TOLD US IT WAS A 767 IN AN EMER DSCNT. I RPTED A TCASII CLB; MAX ALT FL337 AND RETURNING TO FL330. THE REST OF THE FLT WAS UNEVENTFUL. RECOMMENDATIONS: REMOVE REQUIREMENT TO LEAVE ATC FREQ TO GET OCEANIC CLRNC. MAKE TCASII DISPLAYS ON THE PFD MANDATORY FOR ALL CRT-EQUIPPED ACFT (THIS IS A SOFTWARE ONLY CHANGE).
