Wake Turbulence

Gerald Quaye is the Article 114 representative for Wake Turbulence. 

Background: Consolidated Wake Turbulence (CWT) will reduce and streamline the number of wake turbulence separation standards implemented in the national airspace (NAS). There are currently three (3) different orders that prescribe wake turbulence separation for facilities:  FAA JO 7110.65, FAA JO 7110.659-RECAT 1.5, and FAA JO 7110.126- CWT. Each order contains different separation minima that often does not work well together, increases workload, creates inefficiencies, and creates a disparity in separation standards between facilities. To maintain safety and increase efficiency, CWT was developed. CWT is a nine (9)-wake turbulence category system that incorporates the most efficient; data driven wake turbulence separation standards. CWT will provide controllers an overall increase in efficiency especially on final and departure. Deployment of CWT began in 2018 and will continue through 2022 culminating with the inclusion of CWT in the 7110.65.  Currently there is no plan to incorporate CWT in the enroute environment. 

Wake Re-Categorization (RECAT) Update 

On March 2, 2021 Charlotte (CLT) Tower/TRACON and Greensboro (GSO) Tower/TRACON along with their underlying facilities successfully went initial operating capability (IOC) and fully converted from RECAT 1.5 to CWT. This milestone represents the fourth facility area to implement CWT in a remote/virtual environment. Training and implementation are upcoming for Memphis, Indianapolis, and Chicago. 

Ongoing Activities  

During the week of March 8th, 2021, the Article 114 wake representative participated in the Multiple Runway Operations (MRO) NextGen Integration Working Group (NIWG) meeting.  There was a range of discussion topics including: Closely Spaced Parallel Operations (CSPO), Minimum Radar Separation on final approach safety analysis, ICAO dynamic wake separation research, and the integrated arrival/departure concept.
