Narrative:

Early morning on nov/fri/91 at XA20Z, an large transport Y flew through their approach course for runway 36L and into our flight path for runway 36R at memphis international airport. The location was approximately 2-3 mi outside of the OM. Our altitude was 3000 ft MSL. Theirs, descending slightly less moving through 3000 ft and returning in a left turn to join the 36L final approach course. Moments before this occurrence, memphis approach control warned us of the impending traffic conflict and gave us the freedom to descend or do what we needed to do to avoid the conflicting traffic. I advised my first officer (at the controls) to remain at our present altitude and to turn right to allow for more space between the 2 flts. A descent would have been very dangerous. The warning by ATC was extremely good and welcome, very timely to say the least. While I do not consider this a near midair, controller reaction and our reaction prevented a dangerous and possibly fatal situation. Traffic avoidance procedures were utilized rather than evasive action.

Narrative: EARLY MORNING ON NOV/FRI/91 AT XA20Z, AN LGT Y FLEW THROUGH THEIR APCH COURSE FOR RWY 36L AND INTO OUR FLT PATH FOR RWY 36R AT MEMPHIS INTL ARPT. THE LOCATION WAS APPROX 2-3 MI OUTSIDE OF THE OM. OUR ALT WAS 3000 FT MSL. THEIRS, DSNDING SLIGHTLY LESS MOVING THROUGH 3000 FT AND RETURNING IN A L TURN TO JOIN THE 36L FINAL APCH COURSE. MOMENTS BEFORE THIS OCCURRENCE, MEMPHIS APCH CTL WARNED US OF THE IMPENDING TFC CONFLICT AND GAVE US THE FREEDOM TO DSND OR DO WHAT WE NEEDED TO DO TO AVOID THE CONFLICTING TFC. I ADVISED MY FO (AT THE CTLS) TO REMAIN AT OUR PRESENT ALT AND TO TURN R TO ALLOW FOR MORE SPACE BTWN THE 2 FLTS. A DSCNT WOULD HAVE BEEN VERY DANGEROUS. THE WARNING BY ATC WAS EXTREMELY GOOD AND WELCOME, VERY TIMELY TO SAY THE LEAST. WHILE I DO NOT CONSIDER THIS A NEAR MIDAIR, CTLR REACTION AND OUR REACTION PREVENTED A DANGEROUS AND POSSIBLY FATAL SITUATION. TFC AVOIDANCE PROCS WERE UTILIZED RATHER THAN EVASIVE ACTION.
