Narrative:

Takeoff, runway 18R, mem. Straight out at about 1500 ft, we got an RA. We increased our climb and turned about 5 degrees to the left and missed the cessna by about 400 ft. Callback conversation with reporter revealed the following information: during callback reporter stated that after he took evasive action and told TRACON there was a cessna on departure route, the controller stated, 'oh yes, he just now showed up.' there was no warning or indication of cessna until after the evasive maneuver. This leads to speculation that the cessna might not have turned on his transponder until he saw the airbus coming at him. Nevertheless, it was TCASII that gave the warning.

Original NASA ASRS Text

Title: TCASII WARNING OF NMAC.

Narrative: TKOF, RWY 18R, MEM. STRAIGHT OUT AT ABOUT 1500 FT, WE GOT AN RA. WE INCREASED OUR CLB AND TURNED ABOUT 5 DEGS TO THE L AND MISSED THE CESSNA BY ABOUT 400 FT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: DURING CALLBACK RPTR STATED THAT AFTER HE TOOK EVASIVE ACTION AND TOLD TRACON THERE WAS A CESSNA ON DEP RTE, THE CTLR STATED, 'OH YES, HE JUST NOW SHOWED UP.' THERE WAS NO WARNING OR INDICATION OF CESSNA UNTIL AFTER THE EVASIVE MANEUVER. THIS LEADS TO SPECULATION THAT THE CESSNA MIGHT NOT HAVE TURNED ON HIS XPONDER UNTIL HE SAW THE AIRBUS COMING AT HIM. NEVERTHELESS, IT WAS TCASII THAT GAVE THE WARNING.
