Narrative:

Departed jfk runway 13R on greki 1 departure. Initial heading 110 degrees to maintain 5000 ft. Departure control 135.9 gave 070 degree heading to 11000 ft. Changed to frequency 126.8 and given heading 050 degree climb to 17000 ft. While on 050 degree heading climbing through approximately 13600 ft got TCASII TA 'traffic, traffic,' with traffic indication at 12:30-1 O'clock position less than 3 NM. Visually observed king air swbound slightly above our altitude. About that time got TCASII RA 'don't climb' with TCASII red symbol inside 2.5 mi arc and appropriate indications on ivsi. Since it was apparent we would pass behind aircraft no evasive action was taken by the captain (PF). We passed behind aircraft approximately 1 mi close to same altitude. ATC then called 'king air 12-1 O'clock position 14500 ft.' I feel that due to heavy traffic over this departure route, as much traffic routing to europe should depart on rtes out over the atlantic (BETTY1, etc). One other note, we all three felt that TCASII 'don't climb' could easily be heard as 'climb.' this can cause confusion at a very critical time.

Title: FLC OF A B767 DURING CLBOUT HAD TCASII TA FOLLOWED BY AN RA TO 'NOT CLB' AS TARGET WOULD PASS OVER IF A CLB WAS NOT MADE. SINCE THE INTRUDER, A BEECH KING AIR, HAD BEEN SIGHTED BY THE FLC, NO EVASIVE ACTION WAS TAKEN. HOWEVER, FLC BELIEVES THAT THE 'DON'T CLB' TCASII WARNING COULD BE MISTAKEN FOR CLB AND THEREFORE, HAVE DISASTROUS RESULTS!

Narrative: DEPARTED JFK RWY 13R ON GREKI 1 DEP. INITIAL HDG 110 DEGS TO MAINTAIN 5000 FT. DEP CTL 135.9 GAVE 070 DEG HDG TO 11000 FT. CHANGED TO FREQ 126.8 AND GIVEN HDG 050 DEG CLB TO 17000 FT. WHILE ON 050 DEG HDG CLBING THROUGH APPROX 13600 FT GOT TCASII TA 'TFC, TFC,' WITH TFC INDICATION AT 12:30-1 O'CLOCK POS LESS THAN 3 NM. VISUALLY OBSERVED KING AIR SWBOUND SLIGHTLY ABOVE OUR ALT. ABOUT THAT TIME GOT TCASII RA 'DON'T CLB' WITH TCASII RED SYMBOL INSIDE 2.5 MI ARC AND APPROPRIATE INDICATIONS ON IVSI. SINCE IT WAS APPARENT WE WOULD PASS BEHIND ACFT NO EVASIVE ACTION WAS TAKEN BY THE CAPT (PF). WE PASSED BEHIND ACFT APPROX 1 MI CLOSE TO SAME ALT. ATC THEN CALLED 'KING AIR 12-1 O'CLOCK POS 14500 FT.' I FEEL THAT DUE TO HVY TFC OVER THIS DEP RTE, AS MUCH TFC ROUTING TO EUROPE SHOULD DEPART ON RTES OUT OVER THE ATLANTIC (BETTY1, ETC). ONE OTHER NOTE, WE ALL THREE FELT THAT TCASII 'DON'T CLB' COULD EASILY BE HEARD AS 'CLB.' THIS CAN CAUSE CONFUSION AT A VERY CRITICAL TIME.
