Issued: 09/2021 Effective: 09/29/2021 0900 (UTC)
Atlanta TRACON Letter to Airmen: LTA-A80-17
Subject: FAA Consolidated Wake Turbulence (CWT) Radar Separation Standards Implementation within Atlanta Terminal Radar Approach Control (TRACON) airspace.
Cancellation: 09/29/2023
Background: Aircraft wake recategorization (RECAT) is the safe decrease in separation standards between some aircraft types. Worldwide collaborative research by experts in wake turbulence, extensive safety and risk analysis, and over six years of RECAT operational experience at major U.S. airports has shown the required separation criteria between certain aircraft could be safely decreased. Consolidated Wake Turbulence (CWT) will take advantage of the continuing evolution of wake mitigation strategies to consolidate the benefits of previous RECAT efforts along with the standards of FAA Order JO 7110.65.
Implementation: Effective 0500 Eastern Daylight Time / 0900 Coordinated Universal Time (UTC), Wednesday, September 29, 2021, Atlanta TRACON (A80) will be designated a RECAT CWT facility and will separate arrivals and departures using RECAT CWT aircraft separation standards. The following Air Traffic Control Towers (ATCTs) within the Atlanta Approach Control areas will also be designated as RECAT CWT facilities and will separate arrivals and departures using RECAT CWT aircraft separation standards.
- Hartsfield-Jackson Atlanta International Airport, Atlanta, GA (ATL)
- Cobb County International Airport – McCollum Field, Kennesaw, GA (RYY)
- DeKalb-Peachtree Airport, Atlanta, GA (PDK)
- Fulton County Airport – Brown Field, Atlanta, GA (FTY)
- Gwinnett County Airport – Briscoe Field, Lawrenceville, GA (LZU)
- Dobbins Air Reserve Base, Marietta, GA (MGE)
- Columbus Airport, Columbus, GA (CSG)
- Lawson Army Airfield, Fort Benning, GA (LSF)
- Middle Georgia Regional Airport, Macon, GA (MCN)
- Robins Air Force Base, Warner Robins, GA (WRB)
- Athens – Ben Epps Airport, Athens, GA (AHN)
Discussion: For Atlanta TRACON (A80), aircraft are grouped into nine Wake Categories based on the following definitions:
Category A – A388/A225
Category B – Upper Heavy aircraft.
Category C – Lower Heavy aircraft.
Category D – Heavy aircraft not included in Category B or C.
Category E – B757 aircraft.
Category F – Upper Large aircraft excluding B757 aircraft.
Category G – Lower Large aircraft.
Category H – Small aircraft with a maximum takeoff weight of more than 15,400 pounds up to 41,000 pounds.*
Category I – Small aircraft with a maximum takeoff weight of 15,400 pounds or less.*
*This order changes the lower boundary of Upper Small aircraft from 12,500 pounds to 15,400 pounds, however, be aware, some Small Plus aircraft are categorized as Lower Small (Category I).
Refer to FAA Order JO 7110.126, Consolidated Wake Turbulence Radar Separation Standards (CWT), for information on aircraft designator types and wake turbulence separation tables. There are no changes to existing radiotelephony usage, “HEAVY” and “SUPER” are used when applicable. RECAT information can also be found in Safety Alert For Operators (SAFO) #12007, #14007, and Information For Operators (InFO) #16016. Additional wake turbulence information can be found in Advisory Circular (AC) 90-23G, “Aircraft Wake Turbulence,” and the FAA “Aeronautical Information Manual (AIM).”
