Narrative:

Following A320 on ILS, we encountered wake turbulence. Advised approach and they advised my aircraft had 5 1/2 mi in-trail on A320 and that I had been above the A320's altitude while being vectored. I advised I was reducing my airspeed to increase separation and had no further wake encounter. (Maybe 5 1/2 mi separation is not great enough following A320 aircraft.)

Original NASA ASRS Text

Title: IMC WAKE TURB ENCOUNTER.

Narrative: FOLLOWING A320 ON ILS, WE ENCOUNTERED WAKE TURB. ADVISED APCH AND THEY ADVISED MY ACFT HAD 5 1/2 MI IN-TRAIL ON A320 AND THAT I HAD BEEN ABOVE THE A320'S ALT WHILE BEING VECTORED. I ADVISED I WAS REDUCING MY AIRSPD TO INCREASE SEPARATION AND HAD NO FURTHER WAKE ENCOUNTER. (MAYBE 5 1/2 MI SEPARATION IS NOT GREAT ENOUGH FOLLOWING A320 ACFT.)
