Narrative:
After takeoff on 27R, departure control gave us 'left turn to 180 degrees climb to 14000.' during the turn passing 10000, TCASII gave TA, then RA 'descend.' we had traffic visually at 2 O'clock, about 5 mi, slightly high. At about same time as RA, departure asked if we had been assigned 10000. We replied 'no, 14000.' when queried, controller could not recall if he had issued clearance to 10000 or 14000. Traffic passed off our right about 5 mi, no conflict.
Original NASA ASRS Text
Title: TCASII ACTIVATED RA DURING CLB OUT FROM ATL. CTLR COULD NOT REMEMBER WHETHER CLRNC ALT WAS 14000 OR 10000. FLC THOUGHT 14000.
Narrative: AFTER TKOF ON 27R, DEP CTL GAVE US 'L TURN TO 180 DEGS CLB TO 14000.' DURING THE TURN PASSING 10000, TCASII GAVE TA, THEN RA 'DSND.' WE HAD TFC VISUALLY AT 2 O'CLOCK, ABOUT 5 MI, SLIGHTLY HIGH. AT ABOUT SAME TIME AS RA, DEP ASKED IF WE HAD BEEN ASSIGNED 10000. WE REPLIED 'NO, 14000.' WHEN QUERIED, CTLR COULD NOT RECALL IF HE HAD ISSUED CLRNC TO 10000 OR 14000. TFC PASSED OFF OUR R ABOUT 5 MI, NO CONFLICT.
