NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Develop annual refresher training for air traffic controllers regarding wake turbulence separation and advisory criteria. The training should emphasize the need for controllers to avoid using phrases or terminology that would encourage pilots of visual flight rules or instrument flight rules (IFR) airplanes to reduce separation to less than that required during IFR operation, thereby increasing the chance for a wake turbulence encounter when operating behind a turbojet airplane.
In plain language (FlightFinder summary)
The FAA is asked to create annual refresher training for air traffic controllers on wake turbulence separation and advisory criteria. The training should stress that controllers must not use wording that might lead pilots of visual or instrument flight rules aircraft to reduce separation below the required minimum in instrument conditions, which could raise the risk of a wake turbulence incident behind a turbojet airplane.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
