Flight Crew Air Transport Pilot (ATP)
Deviation - Speed All Types; Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Environment - Non Weather Related; Procedure
Cruise ....wake turbulence caused an aircraft over speed. Mach 0.83 for three (3) seconds.I can't really give an answer to help prevent this occurrence. It is not uncommon for this to happen and cannot be addressed until it occurs. Once it occurs we can make certain changes such as changing altitude or flight path.
A320 pilot reported a short-duration overspeed occurred in cruise flight; and cited wake turbulence as the probable cause.
