Inflight Event / Encounter Wake Vortex Encounter
Flight Crew Took Evasive Action
Procedure; Environment - Non Weather Related
We departed Runway 18L in sequence behind a B747. During the climb ATC requested a right turn to 330; then direct BLECO fix. As I began the turn I experienced wake turbulence which caused an uncomanded roll and momentary 'bank angle' aural warning. I corrected the bank and leveled the wings before continuing the turn to BLECO. No other incident occurred after that. Uncommanded roll due to B747 wake turbulence. [We suggest] additional spacing between aircraft would have prevented the roll.
Reporter emphasized his concern that spacing from heavy aircraft be increased.
A 747 was given an intersection take off clearance on Runway 18L from Taxiway Y or Z; (can't recall). We were given a line up and wait followed by a takeoff clearance from WF (full length). Take off was uneventful. Turning to the north around the fixes BPARK or YAMEL we experienced strong turbulence and a momentary 'bank angle' aural warning. The Captain (Pilot Flying) took immediate corrective action to stabilize the aircraft before continuing the turn to BLECO. We entered the wake turbulence of a Boeing 747 on departure. Increased spacing for Heavy/Jumbo departures and maybe consider alternate departure procedures.
EMB-175 flight crew reported encountering wake turbulence departing DFW in trail of a B747.
