The FAA published updates to the wake turbulence separation categories on October 22 for Louisville, Miami, Cincinnati, San Francisco, Atlanta and Philadelphia airports based on improved understanding of how wake vortices behave. Categories are now based on weight, certified approach speed and wing characteristics. Special consideration will be given to aircraft with limited ability to counteract adverse rolls.

The Airbus A380 Wake Vortex Steering Group recently issued new recommendations for A380 wake turbulence spacing. The group includes representatives from the FAA, JAA, Eurocontrol and Airbus. Vertical, horizontal and holding spacing remains the same as for other aircraft; for these regimes the A380 was found to have wake characteristics similar to those of the Boeing 747.
