A NMAC OCCURS ABOUT 1200 FT AGL AFTER TKOF ON THE INITIAL NOISE ABATEMENT DEP.

Narrative

SHORTLY AFTER TKOF FROM DCA; AS WE WERE CLBING THROUGH APPROX 1200 FT AGL/MSL ON THE 185 DEG RADIAL; WE GOT A TCASII ALERT. THE 'MONITOR VERT SPD;' AURAL SOUNDED TWICE. I IMMEDIATELY CHKED THE VSI AND OBSERVED A RED ARC COMPLETELY AROUND THE INST; FROM 6000 FPM UP TO 6000 FPM DOWN. SEEING NO GREEN FLY TO AREA ON THE INST; I SHIFTED MY SCAN COMPLETELY OUTSIDE AND PICKED UP A LIGHT TWIN ENG ACFT (I BELIEVE A CESSNA); ABOVE AND SLIGHTLY TO OUR L. I STARTED A DSNDING R TURN; ARRESTING OUR CLOSURE RATE. ONCE OUR CLOSURE RATE WAS ARRESTED; WE CALLED TWR WHO WAS CALLING THE OTHER ACFT; AND AS SEPARATION WAS GAINED WE CONTINUED OUR CLB. AT CLOSEST PROX WE PASSED ABOUT 50 FT FROM THE TWIN; WE WERE AT LOW SPD; FLAPS 15 DEGS; LESS THAN 150 KTS; WAITING TO REACH CLEAN UP ALT. THE TWIN APPEARED CLEAN IN A R TURN CLOSING FROM L TO R. IN RETROSPECT; THE FOLLOWING CONTRIBUTING FACTORS PROBABLY LED TO THIS CONFLICT: NO GND BASED TA WAS GIVEN TO US REGARDING THE OTHER ACFT. ONCE THE 'MONITOR VERT SPD' WARNING WAS GIVEN; THERE WAS NO FLY TO AREA INDICATED; JUST A SOLID RED BAND. THE VISIBILITY IN THE B-727 IS LIMITED BY A BEAM BTWN THE EYEBROW WINDOW AND THE SIDE WINDOW. THE SUN WAS BLINDINGLY BRIGHT IN THE UPPER FORWARD PORTION OF THE SIDE WINDOW. THE PRIME CONTRIBUTING FACTOR; HOWEVER; WAS THE NON COMPLIANCE WITH CLRNC BY THE OTHER ACFT.
