A ground-based server is configured for identifying encounters of aircraft with wake turbulences generated by at least one other generating aircraft. The ground-based server is configured for: collecting avionics data for an in-flight aircraft and traffic data for one or more other aircraft in flight at a first flight time of the in-flight aircraft; determining that the in-flight aircraft was near a wake turbulence estimated, using the traffic data, to be generated by another aircraft; determining that the in-flight aircraft experienced at the first flight time a severe impact; determining that the in-flight aircraft experienced at the first flight time at least one of: one or more uncommanded forces and moments, and a wind signature indicative of wake turbulence; and in response, generating a report of a wake turbulence encounter for the in-flight aircraft at the first flight time.
