FAA Order 7110.659A, effective June 1, will recategorize the guidelines air traffic controllers use to provide proper wake turbulence separation. The new standards are expected to increase airport capacity while reducing both arrival and departure delays.
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.
Hawker Beechcraft King Air B100, Benavides, Texas, Oct. 26, 2009–After taking off from Garner Field Airport in Uvalde, Texas, on a Part 91 IFR flight, the King Air (registered to Mazak Properties) crashed during an encounter with severe weather.
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.
