From the USAF Mishap Report: “
e. Understanding Wake Turbulence - Every aircraft generates wake turbulence while in flight. Wake turbulence is a function of an aircraft producing lift, resulting in the formation of two counter-rotating vortices trailing behind the aircraft. Wake turbulence from an aircraft can affect other aircraft due to the strength, duration, and direction of the vortices. Pilots should always be aware of the possibility of a wake turbulence encounter when flying through the wake of another aircraft and adjust the flight path accordingly.
Wake turbulence procedures at Hill AFB are intended to reduce the likelihood of following aircraft from entering wake turbulence vortices with the primary danger being an unexpected rolling motion close to the ground due to flight within the vortex,
not because of an impact to the air data system of the F-35. Most F-35 pilots interviewed for this investigation and the accident investigation board’s F-35A Pilot Member, regularly experience wake turbulence while flying the aircraft. The F-35 has over 600,000 flight hours and this is the first known occurrence of wake turbulence having a catastrophic impact on the Air Data System.”
