Narrative:
Large transport was cleared for takeoff. Once he was airborne, we were cleared for takeoff. Immediately after takeoff we encountered the large transport wake turbulence. It took almost full aileron input to keep from rolling past 45 degrees. The large transport is not considered a heavy category aircraft. The wake I encountered was considerably more than normal. Suggest there be an intermediate category with some timing restrictions, especially for landing. If more information is needed, please call.

Title: MLG EXPERIENCED WAKE TURBULENCE FOLLOWING A NEW TYPE MLG NOT DESIGNATED AS HVY.
Narrative: LGT WAS CLRED FOR TKOF. ONCE HE WAS AIRBORNE, WE WERE CLRED FOR TKOF. IMMEDIATELY AFTER TKOF WE ENCOUNTERED THE LGT WAKE TURB. IT TOOK ALMOST FULL AILERON INPUT TO KEEP FROM ROLLING PAST 45 DEGS. THE LGT IS NOT CONSIDERED A HVY CATEGORY ACFT. THE WAKE I ENCOUNTERED WAS CONSIDERABLY MORE THAN NORMAL. SUGGEST THERE BE AN INTERMEDIATE CATEGORY WITH SOME TIMING RESTRICTIONS, ESPECIALLY FOR LNDG. IF MORE INFO IS NEEDED, PLEASE CALL.
