Narrative

CAPT WAS FLYING ACFT FROM LEFT SEAT. PASSING 2000' MSL ON DEP OFF RWY 26R AT ONT WE BEGAN A 20 DEG LEFT BANK TURN DIRECT THE PDZ VOR PER THE PRADO SID WITH CLRNC TO 7000'. WE WERE CLBING AT ABOUT 1000 FPM AND ACCELERATING FOR FLAP RETRACTION. DEP CTL CALLED 'TFC AT 1 O'CLOCK; EBND; ALT UNKNOWN;' AND SUGGESTED A HDG OF 090 DEGS IF TFC NOT IN SIGHT. THE F/O ACKNOWLEDGED THE CALL AND STATED THAT WE WERE ALREADY IN A TURN. AT THIS POINT WE WERE NOT ONLY IN AN ARSA; BUT ALSO IN AN ATA. AT ABOUT THE SAME TIME THE F/O SPOTTED THE TFC ON A CONVERGING COURSE; AND WITH NO TIME FOR EXPLANATIONS; TOOK THE ACFT AND TURNED RIGHT TO EVADE THE RED AND WHITE SMA. AS WE ROLLED THROUGH 0 BANK I JUDGED THAT THE SMA WAS AT OUR SAME ALT (APPROX 3300') IN LEVEL FLT; EBND. THE SMA TOOK NO EVASIVE ACTION AND GAVE NO INDICATION THAT HE HAD SEEN UP DESPITE OUR SIZE; BRIGHT COLORS AND LNDG LIGHTS. THE SMA WAS SQUAWKING 1200 WITH NO MODE C READOUT (ACCORDING TO DEP CTL) AND APPARENTLY NOT TALKING TO ANY CTLR. WE THANKED THE CTLR FOR HIS TIMELY CALLOUT. (I DON'T THINK THE 090 DEG HDG WOULD HAVE WORKED; HOWEVER; AND WE PROBABLY WOULD HAVE BELLIED INTO THE SMA.) FORTUNATELY MY F/O WAS AN EXPERIENCED FIGHTER PLT (AIR GUARD) WHO INSTINCTIVELY KNEW WHICH WAY TO TURN TO INCREASE SEP AND AVOID THE CONFLICT. I WISH WE HAD GOTTEN AN N #! THIS INCIDENT POINTS OUT ONCE AGAIN THE NEED TO 'CLEAR; CLEAR; CLEAR' WHEN OPERATING IN VMC AND TO FOLLOW MOTHER'S ADVICE TO LOOK BOTH WAYS WHEN TURNING. W/O THE CTLR'S WARNING AND A SET OF FIGHTER PLT EYES WE MIGHT HAVE BEEN BLINDSIDED.
