4-6-7 Guidance on Wake Turbulence

1. To date, wake turbulence has not been reported as a significant factor in DRVSM operations. European authorities also found that reports of wake turbulence encounters did not increase significantly after RVSM implementation (eight versus seven reports in a ten-month period). In addition, they found that reported wake turbulence was generally similar to moderate clear air turbulence.
2. Pilot Action to Mitigate Wake Turbulence Encounters
   1. Pilots should be alert for wake turbulence when operating:
      1. In the vicinity of aircraft climbing or descending through their altitude.
      2. Approximately 10-30 miles after passing 1,000 feet below opposite-direction traffic.
      3. Approximately 10-30 miles behind and 1,000 feet below same-direction traffic.
   2. Pilots encountering or anticipating wake turbulence in DRVSM airspace have the option of requesting a vector, FL change, or if capable, a lateral offset. 

   3. NOTE-

      1. Offsets of approximately a wing span upwind generally can move the aircraft out of the immediate vicinity of another aircraft's wake vortex.
      2. In domestic U.S. airspace, pilots must request clearance to fly a lateral offset. Strategic lateral offsets flown in oceanic airspace do not apply.
