Narrative

ATLANTA APCH USING RADAR VECTORS TO SEQUENCE ARRS; THEN ISSUING CLRNC FOR VISUAL APCH BEHIND TFC. FLT WAS VECTORED FROM BASE TO FINAL AND PLACED APPROX 2 MI BEHIND MD80 JUST OUTSIDE OM ON RWY 8L. ASSIGNED SPD OF 160 KTS TO CATTA/OM. APPEARED TO BE CLOSING ON MD80; BEGAN SLOWING. INITIAL FLAPS SET 15 DEGS; GEAR LOWERED AND PROPS SET TO 100 PERCENT. SECOND FLAP SETTING TO 25 DEGS; ACFT SLOWED TO 132 KTS AND 1 DOT ABOVE ILS GS. SUSPECT WAKE TURB FROM ARRIVING MD80; EMB120 ROLLED RIGHT WITH 1.15 G VERT ACCELERATION. FULL L AILERON BROUGHT BACK TO WINGS LEVEL. FLT DATA DOWNLOAD INDICATED ROLL ATTITUDE OF 05 DEGS. APCH CONTINUED WITHOUT INCIDENT. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING: THIS CALLBACK IS A RESULT OF WAKE TURB CALLBACK QUESTIONNAIRE. RPTR DID NOT HAVE A VERY SEVERE ENCOUNTER WITH WAKE NOR DID IT LAST VERY LONG. HIS MAIN CONCERN WAS THAT THE FLC FELT THEY HAD PLANNED WELL TO AVOID THE WAKE. THEY WERE FLYING HIGH AND STILL ENCOUNTERED IT. HIS MAIN SUGGESTION IS TO FIND A WAY TO KEEP THE HIGH FLYING FAST TFC FROM DSNDING THROUGH THE SMALLER ACFT FLT PATH. THAT IS WHAT HE FEELS WOULD SOLVE MOST OF THE WAKE PROBS.
